The Earth: Shape and Size Oceans on the Earth

The Earth: Shape and Size Oceans on the Earth

Earth's Ocean consists of saltwater and animals that covers nearly 70% of the Earth's surface and contributes to 97% of the Earth's water. The Pacific Ocean is the largest ocean on Earth.

Oceans are the backbone of the Earth that consists of 97% of the Earth’s water and millions of water bodies to maintain ecological balance. Five oceans on the Earth contributed the most to the surface of the Earth. The names of the five oceans are the Pacific Ocean, the Atlantic ocean, the Indian Ocean, the Southern Ocean and the Arctic Ocean. The Pacific Ocean is the largest ocean on the Earth that has a length of 168,723,000 square kilometres. Ocean water contains large quantities of dissolved gases like carbon dioxide, oxygen and nitrogen. Therefore, the geographical area of the Earth’s surface is primarily covered by ocean water.

Geographical structure of Earth:

Earth is not a perfect share, and it is an oblate spheroid that flattens at the pole and bulges at the equator. The length of the Earth is 12,756 km at the equator and 12,714 at the pole end. The shadow of the Earth in the lunar eclipse is round. Seawater in the Earth covers approximately 361000000 square kilometres, and the oceans are the principal components of the planet’s hydrosphere. The Ocean is an integral part of life on the planet. Ocean influences the weather and temperature on the Earth’s surface by transferring heat or absorbing heat. The climate change and weather patterns, carbon cycle largely depends on the surface of the Ocean. Oceans are divided into vertical and horizontal poles based on physical and biological conditions. “The pelagic zone” consists of a water column from the Earth’s surface to the ocean floor throughout the surfaces of the Ocean. 

Oceans in the Earth:

Five oceans on the Earth are the backbone of weather formation and climate change. The length of the oceans determines how to transfer air from the Earth’s surface to the water column of the Ocean. The water column in the Ocean is further divided into two columns depending on the depth and the presence of light. For example, the Arctic ocean is divided by the underwater ridge named Lomonosov ridge into a 4500 m deep Eurasian basin and 4000 metres deep North America basin. The average depth of the topography of the Arctic Ocean is 1038 metres. The primary flow of the water to the Arctic Ocean comes from the “Atlantic via the Norwegian current”. The primary outflow of the water comes from the “East Greenland Current”. The Southern Ocean is the Earth’s 4th largest Ocean, and it encircles Antarctica, which is divided among the Indian, Atlantic and Pacific oceans.

Description of the largest Ocean:

The Pacific Ocean is the largest water body on the Earth that consists of millions of water bodies that maintain geographical diversity. The Pacific Ocean expanded about 60 million square miles from California to the country of China. Some of the specific regions of the Ocean extend 10,000 feet below the surface water. The exploration of the Ocean provides certain knowledge of the structure of the Earth’s surface. However, human activities like deforestation, industrial fishing, and the carrying of fossil fuels in the Ocean reduce biodiversity by hampering the life of the water body. The Pacific Ocean consists of 46% of the Earth’s water surface and has a huge impact on global weather change. The Pacific Ocean consists of 32% of the Earth’s total surface. The average depth of the Pacific Ocean is approximately 4,280 metres, and the western pacific consists of several seas.

Description of the ocean water:

The temperature of ocean water depends on the radiation of the sun’s rays on the surface of the water. The volume of the water in all the Earth’s oceans is approximately “1.33 billion cubic kilometres”. Saltwater comprises 97.5% of the total ocean water that maintains the Earth’s vapour, a crystal of ice on the surface. The freshwater composition of the Earth’s Ocean is only 2.5%, of which 68.9% is in the forms of ice in the arctic region. 30.8% of the Earth’s surface water is groundwater, and only 0.3% is freshwater. The increasing carbon emission on the Earth results in a high amount of ocean acidification.

Conclusion:

Oceans are the structural components of the Earth’s surface, and it maintains the ecological balance on the planet. The formation and transfer of air are changed according to the flow of water in the oceanic region. An increase in ultraviolet radiation threatens the level of water in the arctic region, creating difficulties for human beings. The Indian Ocean lies between the oceanic ridge’s African, Indian, and Antarctic plates. The ocean structure’s geographical analysis helps determine the value of sustainable practices. The circulation of the water in the deep is mostly formed by the water flowing from the region of the Atlantic Ocean. Oceans are the main components of the Earth’s relative humidity.
