Paraguay is a landlocked country covering an average of 406750 square kilometers. It is located in South America. Its prominent physical feature of the country is the Paraguay River that separates the country into two regions with distinct differences in climate, and land topography. Industrialization and other human activities have adversely affected the country’s environment. The current environmental issues are water pollution caused by industrial discharges into rivers and streams, deforestation and encroachment into wetlands. The rate of deforestation is quite high due to weak government policies on deforestation and weak implementation of forest protection policies. The country ...

The environment of Nepal was affected by deforestation, encroachment, and soil erosion. There is also contamination in its water. Back in the 1970s, the country’s forestland decreased from 30% to 22% of its overall area. This was due to the timber of firewood which was the source of fuel in Nepal. Erosion also caused the decrease in land which was about 240 million cu m of topsoil every year. In 1957, the forests of Nepal were already nationalized but there were few deforestation activities that were done. However, in 1980, the country started a deforestation program which included ...

Question 1

Geography is unique since it is the most basic and essential science. The creation of the field of geography is through human curiosity concerning the atmosphere and the environment in the world. It becomes unique because it is both a social and natural science. The core unifying factor between human and physical geography is the environmental determinism concept which argues that the natural environment directly influences human beings’ moral, mental and physical habits. Both depend on each other while on the earth’s surface since a majority of human’s activities are through the exploration of physical activities.

Introduction Wheat (Triticum sp.), an extensively adapted crop, is one of the primitive and primary staple food crops in the world. Wheat is cultivated from temperate; dry to irrigated or rain-fed areas, to warm, humid or cold conditions. Such a high adaptability is attributed to its intricate genome (Acevedo et al., 2002). Wheat cultivation covers more land area compared to other commercial crops and endures to be an essential food grain for humans (Curtis, 2002). Estimations reveal that by 2050, the population of the world will reach 9.1 billion (34 percent greater than today); correspondingly, the food requirement and ...

Santiago, popularly known among the locals as Santiago de los Caballeros is located at the heart of the Cibao Valley, in central Dominican Republic and is considered to be the second largest country of the Republic. Due in large parts to its location on the island, tropical climate prevails in the city for most parts of the year. To put it into context, average temperatures throughout the year hover around the 25 degree Celsius or 77 degree Fahrenheit, with days that offer sunlight without the heat making the weather intolerable . This is why the long, sunny days on the ...

Global warming is one of deleterious consequences of climatic change. Increased level of carbon dioxide emission and other pollutants such as chlorofluorocarbons contribute to unprecedented increase in the atmospheric temperature which dictates human survival in this planet. A continuation of this trend will eventually lead to a wipe out of the living creatures on the earth’s surface through resulting effects such as heat wave related deaths as well as flooding. Global warming has contributed to several cases of heat wave related deaths around the world. It has also denied wild animals their natural habitats through forest fires which ...

Research Question- Why is it a problem if the earth’s average temperature gets a little warmer?

1.1 Results The average rising temperature can have vast impacts only by slight increase. The vast impact the average temperature can have can be shown with the average temperature in the last ice age, when the average temperatures were only around 5 degrees Celsius lower than today’s average temperatures. From the Figure 1 it is seen that the global average temperature, which combines the surface and ocean temperature have been on the rise and have reached the highest levels in the ...

Global warming and climate change are two different terms that have been used over the years to describe different phenomena. Global warming refers to a subsequent increase in the global average temperature (Black & Weisel 5). On the other hand, climate change refers to global climate changes due to increasing average global temperatures brought by changes in rain patterns, increased drought and heat waves. These future projections in the change of global rainfall patterns can be derived from the Intergovernmental Panel on Climate Change (IPCC) reports over the years. The argument that the use of term global warming has been ...

The air near the surface will usually become warmer throughout the day. This is one of the main reasons why it is unstable. Then at night, the air that is close to the surface will begin to cool. This is going to form a temperature inversion or a stable atmosphere.2. Inversions aloft are sometimes called “capping inversions” or “lids”. Why?

This is because it is like putting a lid on the atmosphere.

The role of people in climate change and its drastic outcomes is undeniable. Burning fossil fuels and deforestation are the main reasons of global warming. While writing the research, much statistics and other data were studied. This information made me understand how serious the problem is. Now it is not possible for me to stay aside of the global problem. Saving the energy and water should be the obligatory things for everyone. The terms “global warming”, “climate change” and ‘global change” seem to be similar, but they have a difference in their definitions. The notion “global warming” refers to ...

Climate change is a very difficult issue to deal with, because all countries pursue different goals and finding a consensus that would satisfy all parties is nearly impossible. There were several attempts to work out the common vision and approaches to the climate change at the beginning of the XXI century, but they were not effective enough. For example, the 2009 Copenhagen Summit was an international event that attracted a very large number of participants and there were many hopes that the new climate change policy and priorities will be developed. However, despite being one the major international events, ...

According to the Nice theory where did the Kuiper belt objects and Oort cloud objects come from?

Kuiper belt objects come from the out edge of Solar System where huge spheres made of rock and ice that circle around Pluto’s orbit. The objects took their name from Gerard Kuiper who suggested that comets may come from the Kuiper belt. This group of planetoids is called Kuiper belt objects (KBO). The first KBO named “1991 QB1” was discovered in 1992. The plant Pluto also belongs to the group of KBO. Some ...

Kinetic theory of matter tries to explain all molecules in terms of motion. The theory posits that every substance consists of many small particles referred to as molecules. Substances in this case are called matter and are in three forms; solids, liquids, and gases. Solids have molecules that are closer to each other by intermolecular forces. Liquids on the other hand have molecules slightly far apart with gases the furthest apart. Furthermore, according to this theory all the molecules are in constant random motion referred to as Brownian motion (Chang, 2004).

The study of heat relates to kinetic theory ...

Difference between freshwater lakes and oceans in terms of the formation of ice

Ocean ice is found in Polar Regions. It covers an area of 25 million square kilometers. Ocean ice forms on the surface of the ocean. It grows and melts above oceans. During winter, ocean ice grows but melts during summer (Thompson & William 1). The occurrence of ocean ice has a direct influence on the global climate. Ocean ice has a bright surface that reflects most of the light that strikes it. The co sequence of this phenomenon is that areas that the ocean ice covers have low absorption of solar energy (Ilker 149). In this regard, the temperatures in the solar ...

Abstract

The seawater forms 97% of water of the world, and the icecaps account for 2%. The portion of water available for human consumption is barely 0.5% and that also in aquifers. The widening gap between availability and requirement of potable water especially in the Gulf countries has necessitated newer methods and technologies for production of water suitable for human consumption. This situation in the Gulf region has developed due to non- availability of surface water, high growth of population and urbanization, and water depletion. The present paper takes account of the desalinization of seawater plant established in Abu Dhabi ...

General description

Mali as a country started its fight against independence in the 1930s. Political opposition did not initially emanate from political parties rather they came from individual that had organized themselves into a number of voluntary organizations (Velton 13). These voluntary organizations compromised of cultural and sporting associations where most educated individual would meet under the French approval. Political parties were formed in the 1940s where the struggle for independence from the French continued. In June 20, 1960, Mali gained its independence from France. Mali covers an area of 478, 640 square miles. It has a population of about 11, 626,219 ...

Nowadays, almost everyone heard at least something about global warming. But, it is not only the change of the climate, but also, the consequences of it. Usually, the term is used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. However, not every scientist believes the global warming is real. But, the data and facts say the planet is warming. Interestingly, the humans knew about global warming even in the late 1800s, but did little to prevent it. So, today, ...

Pasteurization is a process that involves heating of raw milk to a certain temperature within a given set of time. This process kills harmful bacteria found in unpasteurized milk, for example, Salmonella, Listeria and E coli responsible for food borne illnesses. These bacterial organisms are responsible for human diseases such as Typhoid, diphtheria, Listeriosis and tuberculosis. The process was first initiated by Louis Pasteur in the year 1864. Pasteurized milk can stay for a certain period without refrigeration. However, refrigeration especially after opening the seal, is still necessary because of some nonpathogenic bacteria that because food spoilage and is non-receptive for heating. ...

Introduction “There is an eternal landscape, a geography of the soul; we search for its outlines all our lives” –Josephine Hart. The famous quote by bestseller novelist is absolutely true and this could be understood well by travelers who are adventurous. For explorers, geography is the landscape that extends up to the horizon and well even beyond it. According to Bonnett (2008), “More specifically, it is towards geography that people have turned when seeking answers to the questions, ‘How and why has the environment altered?” (p.4). Mapping is a popular activity with which people tend to associate geography more specifically ...

Is global climate caused by human activities?

Currently, the question on whether human activities cause global warming has sparked debates from environmental experts. The massive growth of the population has increased growth of consumption, and this poses threats to the global climate. The rise of the earth’s temperature is mainly caused by the gases released by greenhouses, especially carbon dioxide. It is saddening to note that the climatic changes affect the physical and biological systems across the universe. Global warming can only be decreased if the carbon output released by human activities is reduced. The Journal of Climate published a paper by Jara Imbers, Chris Huntingford, ...

Industrial Pollution Effects on Global Warming

Introduction Changing climate is also changing our economies, health and communities in almost every part of the world. The fast and rapid industrialization in the past increased the need of thermal power plants and other industries run by fossil fuels. They contributed in atmospheric changes drastically by emitting different pollutants including Co2, CO, SOx and NOx. They have not only threatened the environment by global warming but also give rise to acid rains. These acid rains destroyed forests that are the major sink of greenhouse gases especially carbon dioxide (Held & Soden, 2006). The variety of chemical emission including ...

Sociology is useful in that it enables you to understand your own cultural and economic orientations as a current residence of United States. It also enables you better to understand the life of the people who live in the country of your destination. You are able to understand their social- cultural values and economic orientation and see if you can adapt to that country’s orientations (Martell, 2010). Most people in some countries may be socially hostile to foreigners especially from United States ...

Global Warming Introduction Global warming is the increase in the average global temperatures that is caused by buildup of greenhouse gases. Carbon dioxide (CO2) is the common greenhouse gas; however others like methane, nitrogen oxides are quantitatively measured on the basis of carbon dioxide equivalents. Air pollution is the main source of the greenhouse gases, especially from industrial settings. Therefore, human activities are the primary causes of global warming through industrial growth, transportation, continued reliance on fossil fuels and removal of carbon sinks. Report by Weart indicated that, the atmospheric temperatures will increase by approximately 1.8-4.0 degrees Celsius by ...

Climatic changes refer to lasting and significant changes in the weather patterns characterized by statistical distribution over a period spanning decades or hundred thousands of years. These changes may encompass extreme weather conditions and may happen due to variations in solar radiation reaching earth, biotic processes, volcanic eruptions, and plate tectonics. Certain activities undertaken by humans have also been recognized as contributing to negative ...

The weather conditions between Oshkosh and Wisconsin are similar. This means that they share both latitudes and longitudes. Snow usually comes at a specific time of the year. This is fall. When it comes, the weather becomes cold. However the ground usually behaves differently. Temperatures are the regulators. When temperatures are high in a place, then the weather becomes warmer or hotter. Nevertheless, when the temperatures are low, a place becomes cooler. Therefore, the grounds nature depends on the temperatures. Weather is not directly related to the ground. When there is snow, the temperature normally becomes cooler. On the contrast, when there ...
