The ocean is a vast body of saline water that covers approximately 71% of the Earth’s surface. It is one of the principal components of Earth’s hydrosphere and is classified into several major parts, including the Atlantic, Pacific, Indian, Southern, and Arctic Oceans. The ocean plays a critical role in regulating climate and weather, supporting a diverse range of ecosystems, and serving as a major resource for food, transport, and recreational activities. It is characterized by its depth, salinity, currents, and temperature variations across different regions. The ocean also acts as a carbon sink, absorbing carbon dioxide from the atmosphere, and it is crucial for the global water cycle. The biological life within the ocean ranges from microscopic phytoplankton to the largest animals on Earth, including whales.
