Ocean Current Causes

1648 Words 7 Pages
Oceans are large bodies of salt water which hold the largest variety of plants and animals on earth. Oceans have currents that travel worldwide, generated by breaking winds and water salinity. These currents also speed up ships and transport nutrients around the world. Marine plants also generate the majority of the world’s oxygen, and regulate climate worldwide. In conclusion, oceans are large bodies of saltwater which hold the majority of life. They also make more of the world habitable. Their currents travel the world, spurred by winds and salinity, and speed up ships and transport nutrients.
Ocean current are mainly caused by wind. Coriolis forces from the Earth’s rotation plus the landform shape the currents. It should be noted that a

Ocean currents can also move this heat, impacting local weather and climate condition. Weather conditions where people live are partially influenced by the surrounding land and surface features. Considering the size of ocean currents, it's no wonder that they affect the weather near the coast and farther inland to a significant degree. When ocean currents change, they modify the sea surface temperature that the atmosphere sees, which drives anomalies in winds, weather and climate across the planet. For example, every three to seven years, the sea surface temperature along the equator in the Pacific Ocean warms by as much as 2 to 3 degrees Celsius. A warm El Niño climate pattern results, which changes rainfall and weather, from flooding in California to drought in Australia. The ocean plays a vital role in Earth’s climate system, shaping weather and climate on land. The ocean can be a major cause of severe weather occurrences like floods and …show more content…
Without it, complex life like us would not be possible. This comes from tiny marine plants called phytoplankton. Like all plants, they use photosynthesis to generate energy and produce oxygen as a byproduct. There are 5,000 species of these little powerhouses at work right now! However, we don’t seem to be very grateful. We dump 8 million tons of plastic into the ocean annually. That’s just the average. In 2010, anywhere from 4.8 million to 12.7 million tons were dumped into the ocean. And that’s still just plastic. According to the National Oceanic and Atmospheric Administration (NOAA), approximately 1.4 billion pounds of trash enters the ocean each year. Global warming affects the ocean too. According to a 2013 report, temperatures in the shallowest waters rose by more than .1 degrees Celsius (.18 degrees Fahrenheit) each decade between 1970 and 2010. That may not sound like much, but corals are bleaching already. Coral bleaching is the starvation, shrinkage, and even death of corals that support thousands of species. Whilst oceans give us most of our oxygen, we are not repaying it properly. We dump millions of tons of toxic waste (most non biodegradable) into the ocean annually. That’s equivalent to dumping one garbage truck of plastic into the ocean every minute. Global warming makes problems worse, destroying coral reefs that support lots of wildlife. We are damaging the ocean severely, even though it gives us
