Essay on Oceans | Ocean Formation, Ocean Rising, Benefits of Oceans
The ocean is one of the most important features of our planet. It covers more than 70% of the Earth’s surface and plays a vital role in the water cycle. The ocean also contains a huge diversity of life, from microscopic plankton to giant blue whales.
The oceans (or world ocean) are the interconnected body of salty water that covers over 70% of Earth’s surface. It moderates Earth’s climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. It has been travelled and explored since ancient times, while the scientific study of the ocean- atmosphere system began only in recent decades.
The word ocean comes from the Greek word ??ea??? (transliterated: Okeanós), one of the oldest names for the body of water that surrounds Earth. The term “world ocean” or global ocean refers to the interconnected body of open water, including areas of open sea and marginal sea. There is only one global ocean, although scientists sometimes refer to different basins in it, such as the Atlantic Ocean, Pacific Ocean, Indian Ocean, Arctic Ocean, and Antarctic Ocean.
The oceans are the result of multiple processes that began over 4 billion years ago when the Earth first formed. At that time, the Earth was a hot, molten ball of rock. As it cooled, the solid crust formed on the surface.
The first oceans were probably shallow and narrow due to the small amount of water on the planet. Over time, as more water was added from comets and asteroids, the oceans became deeper and wider.
Life Under Ocean
The oceans are home to a huge variety of plant and animal life. Some creatures, like whales and dolphins, live in the water their whole lives. Others, like turtles and seals, spend most of their time on land but go into the ocean to eat.
There are over 1 million known species of animals that live in the oceans, and scientists believe there are many more that have not yet been discovered. Some of the most popular ocean animals include fish, sharks, dolphins, whales, and penguins.
Benefits of Ocean
The oceans play a vital role in regulating the Earth’s climate. They absorb carbon dioxide from the atmosphere and help to keep the planet cool. The oceans also produce oxygen that we need to breathe.
The oceans are a major source of food for people around the world. Fish is the main type of seafood that people eat, but there are also shellfish, such as shrimp, crabs, and lobsters. Seaweed is another type of food that comes from the ocean.
The oceans are facing a number of serious pollution problems. The most common type of pollution is plastic. Every year, millions of tons of plastic end up in the ocean. This plastic pollutes the water and hurts or kills marine life.
Oil spills are another type of ocean pollution. When an oil tanker leaks or spills its oil, the oil pollutes the water and harms marine life.
Ocean rising is the increase in the average height of the world’s oceans due to the melting of ice sheets and glaciers on land, as well as the expansion of seawater as it warms. The main cause of ocean rising is human-induced climate change, which is causing Earth’s average temperature to increase.
Over the past century, the average height of the world’s oceans has risen by about 8 inches (20 centimeters). This may not sound like much, but it is already having a major impact on coastal communities around the world. As ocean rising continues, it will cause even more flooding and damage to property, as well as displace millions of people who live in low-lying areas.
Ocean rising is a major threat to humanity, and we must act now to reduce our emissions of greenhouse gases and slow the warming of the planet. We can do this by using less fossil fuels, planting trees, and protecting natural areas like forests that absorb carbon dioxide from the atmosphere.
