Essays on Ocean Current

Part 1

The current theory regarding the evolution of the earth’s ocean is that water is present during the formation of the earth. Most of the discovered materials which was more than 4 billion years old also contained evidences of the present of water (Genda, 2016). Some scientists suggest that the water on earth emerged in the surface when steam was released in the volcanoes. Additional water emerged in the surface of the earth coming from meteorites and comets during the formation of the earth. The continuous addition of water from volcanoes and meteorites or comets led to the formation ...

There are many limiting factors in a marine ecosystem. These limiting factors interact in many ways to form different features and also affect the marine ecosystem. This paper analyzes the relationship between the temperature of the region and rate of evapotranspiration, the upwelling of water and the speed of wind, the ocean currents and the climate experienced, and nature of rocks and type of features formed. The temperature of the surrounding region in an ocean is very important. When temperature is high, the evaporation from the surface of the ocean would be high (NSIDC, n.d). In addition, high temperature ...

Wind is a major limiting factor in the marine ecosystem. Wind affects waves, dune system, sediment transportation, currents, and weather. Wind has profound effects on the waves. As wind move over the surface of the oceans, the abrasions between the wind and the water surfaces lead to formation of waves. The speed of wind also affects the size of the waves formed. When the speed of the wind is very high, the abrasion between the wind and the surface of the water increases leading to huge waves. In the event that the speed of the wind is low, the waves ...

Global Warming: Cause and Mitigation

Global Warming: Cause and Mitigation Global warming is the change in the climate due to the rise in the temperature of the earth’s atmosphere and the oceans. Ocean and climate are linked to each other and so oceans bear the effect of climate change as evidence by increase in the sea level and change in the temperature. This rise in the temperature of the earth’s surface caused increased global warming of the climate. This change in the climate in turn impacts the health of marine species, ecosystem and also humans. Similarly the greenhouse gases produced by ...

Patterns of Surface Ocean Currents

Surface currents are found in the upper four hundred meters of an ocean body and they form major patterns such as eddies, upwelling, and gyres (Garrishon, 2007). Surface currents result from wind energy that is concentrated in both north and south hemispheres forming trade winds which are easterlies and westerlies (Garrishon, 2007). Waves on the sea surface transfer some of the energy from the moving air to the water by friction. Pulling of wind on the surface of ocean causes an accumulation of water with the water displaced underneath the wind forming the movement. ...
