Free Movie Review On Nova Video Earth From Space

The earth as we see it is composed of different components that make up the earth we know day. These components vary from the physical elements that are seen by the human eye to strange and unexplained forces that are in the visible elements of the earth. This has triggered the scientists to devise ways in which they will understand fully what happens on earth and why it is in the shape it is today. The scientists through governments have sent into space different space satellites that are able to help them get the desired knowledge of the different components of the earth both on the surface as well as deep below the surface. These space satellites are different and are assigned different study topics that they cover. All of them together are aimed at combining the information that they derive so that they give the best understanding of the earth surface. This movie has elaborated how a view from above the earth provides information that human beings would have not come across from the earth surface.
There are a lot of natural incidences that are found on earth that have been seen to be unrelated but recent studies show that indeed they are related. These incidences and natural happenings have been recorded in areas that are as far as thousands of miles apart and yet they are related. All the different incidences that happen across the world have been studied under different instruments that analyze to the tiniest detail of the natural happenings. The different satellites that have been placed hundreds of miles above the earth surface help in the careful and more detail analysis of what happens on the earth surface. These satellites carry different and more exquisite sensor detectors that have different purposes to help human beings solve the puzzle of what the earth is.
The first step of understanding what happens on earth is by understanding the massive effect the sun has over the planet of earth. The sun lies about ninety three million miles away and releases energy that is radiated onto the planets that surround it. The energy that is released by the sun onto the earth has massive effects from affecting the lives of animals and plants to influencing the incidences that happen on the earth surface. The energy that is released by the sun is great and requires special equipment to measure and release the needed statistics so as to determine the extent in which the energy released by the sun impacts the activities that happen on the earth surface.
A satellite by the name of Suomi enables the scientists to have a close look of the effects of the energy released by the sun since it operates by analyzing the electromagnetic radiation released by the sun. This radiation is measured against a spectrum that is invisible to the human eye. The full spectrum that is used to measure the extent of the radiation is long and the satellite is able to measure it all. It is able to do this by concentrating on the infrared rays and the ultraviolet rays that are not visible to the human eye.
The sun releases energy that is directed towards the earth. However, different parts of the earth receive different amounts of this energy as recorded by the said satellite. The Polar Regions receive the least of the energy released by the sun. These regions reflect most of the heat that falls on the region. That is why they are able to maintain low temperatures throughout the year. The equator region on the other hand receives most of the energy that is released by the sun. This energy is received in terms of heat and is responsible over several weather and natural happenings in the world. In most areas around the equator, the sun heats up the water masses and large amounts of water vapor are released into the air. These amounts of water vapor are responsible of the formation of the clouds that at different times develop into storms that are experienced at the adjacent areas and other far areas.
This video assesses how the storms are formed and powered by the effects of the sun and how they have affected other parts of the earth. There are three dimensional images seen in the movie that simulate the different events that happen in the formation of a storm. The heat that is released by the sun heats up the water masses and water vapor is formed. The heat is then carried by the water vapor and powers the storms that happen on different parts of the earth. Hurricane Katrina was used as an example in the study of the formation of storms and its relation to other events on earth. The satellites that study the different wavelengths reveal that the sun is indeed the real cause of the hurricane. There are water vapors that are seen in the hurricane power the hurricane to the cause of destruction on the earth surface. The sun is responsible for the formation of the monsoon tropical climate that dictates the weather patterns in parts of the tropical areas of the earth surface. The relationship between these winds and the dry climate of deserts such as the Atacama Desert are shown.
The Antarctica has remained a store of surprise events that happen on the earth. The Antarctica varies in size depending on the season of the year. During winter periods, large parts of adjacent ocean water freeze to form the larger Antarctica while on summer periods the larger parts of the ocean water melt into ocean water that flows into the adjacent oceans. This creates a cycle that repeats itself yearly. The region manages to retain the extremely low temperatures due to the presence of a storm that is present in the area. There are different things that happen both on the surface and well below the surface of the sea in the Antarctic region that explains different events that happen both close to the region and in areas far from the region. There is infrared equipment such as one on the Aqua satellite that helps reveal the activities happen both on the surface and well below the surface of the oceans. This has revealed of the activities that take place on the ocean floor and the movements of the water under the surface. There is the formation of brine in the Antarctica region that moves under the frozen surface under large oceanic waterfalls that direct the brine to other areas towards the equator on the ocean floor. As the brine moves towards the equator, it mixes with the rest of the water on the ocean and moves up. The continental winds blow the water towards the Antarctica region and the cycle continues.
The activities that happen on the surface of the oceans are greatly influenced by the activities that happen on the oceanic floors as the terrain below the ocean floor. There are satellites that are used to observe the tiny movements of the earth’s crust and over time, there are movements that have been registered by these satellite equipments. The movement of the earth’s crust has been used to explain the causes of different earthquakes that happen in different parts of the world as well as the eruption of active volcanic mountains that erupt in different parts of the world. There are satellites that are used to monitor the movement of the terrain below the sea through high sensitive radar equipment that makes sure that the tiniest movement is recorded.
This has shown what happens before an active mountain erupts and can detect the movements well long before the mountain erupts. The movie shows the relationship that is formed between the oceanic organisms and the natural events that happen beneath the sea surface. The formation of volcanic mountains beneath the surface of the sea results in the formation of the nutrients that the sea organisms require in their survival. This creates an ecosystem where even the human benefit by fishing from these areas. The MODIS on the Aqua satellite examines the different things that happen for the formation of optimal conditions for the survival of different sea organisms.
The Sahara desert is another feature that is analyzed in this movie and how it relates to other features and events in the world. From the satellites, there are different features that are seen in the Sahara that help explain the different things that are not seen by the human eye. Through the satellites, there has been determined the remains of what was once the largest fresh water lakes. This was evidenced by the diatomite that is found in the depression. These are the remains of planktons that are a necessity for the survival of fish. The movie then explains how the diatomite in the Sahara re-enters the life chain of the organisms that are found on the earth surface. The winds that are available in the Sahara region blow up little pieces of the diatomite and thus the small pieces are carried to the nearby oceans where they dissolve in the water and are ingested by the organisms that are in the sea water.
The atmosphere is composed of different gases that combine to enable the support of life on the earth surface. There are different gases that change in volume at different times of the day and control the life of organisms on the earth surface as well as those in the sea. The plants use up the carbon dioxide gas and release the oxygen gas during the day. This is used in the synthesis of the food that is necessary for the plants to grow. During the night, the satellites show that the levels of carbon dioxide increase during the night since the plants do not use up the carbon dioxide gas during the night. Different activities such as the lightning determine how the nitrogen gas is mixed with the oxygen gas to form the nutrients that are necessary for the growth of the nutrients. The different radiation levels are also monitored over the satellites.
In conclusion, the movie that shows that the earth is composed of different components that make up the earth and the events that happen around and in it. These components of the earth are related and help in the study of the events that happen in the earth. The use of satellites that are positioned high above the earth has helped in the careful study of the earth and the events around it. These satellites that are fitted with high sensitivity scanners have helped the study of different things such as the energy radiation that is in the earth that is released by the sun as well as what happens below the surface of the sea as well as the movements that happen below the surface of the ocean floor. The movie has combined the different computer simulations to make this idea well understandable to the human beings that watch this movie. The different reviews by the scientists from NASA have helped elaborate to simple terms the different complex things that are seen from space. The relationship between these events and the lives of human beings as well as other organisms has also been studied. The formation of the nutrients that are a necessity for the survival of the organisms has also been studied. The gases that make up the atmosphere and how they change in volume during different times of the day has also been studied and elaborated in the movie. The levels of radiation as well as the different magnetic fields that are on the earth surface are also analyzed and how they relate to the lives of human beings and other organisms. The movie generally analyzes what the human eye could not analyze and helps the growth of the knowledge of the earth and its components.
