Class 11 Geography Chapter 12 Water Oceans Solution

Oceans cover a vast majority of the Earth’s surface and play a crucial role in shaping our planet’s climate, weather patterns, and overall ecosystem. In this chapter, we explore the significance of oceans, their characteristics, and the diverse marine life they support.

Oceans are immense bodies of saltwater that cover about 71% of the Earth’s surface. They are primarily composed of the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern Ocean, and the Arctic Ocean. These interconnected bodies of water regulate heat distribution across the Earth, influence weather systems, and act as carbon sinks, absorbing a significant amount of carbon dioxide from the atmosphere.

The ocean’s physical characteristics are influenced by factors such as temperature, salinity, density, and currents. The surface temperature varies depending on latitude, with warmer temperatures near the equator and colder temperatures near the poles. Ocean currents, driven by factors like wind, temperature, and the Earth’s rotation, distribute heat, nutrients, and marine organisms around the globe.
