What is 2/3 of the Earth?
Since 2/3 of the Earth is covered by water, the Earth is also called the blue planet and the watery planet. The hydrosphere plays an important role in the existence of the atmosphere in its present form. Oceans are important in this regard.
What is a third of the Earth’s surface?
About one third of the earth’s surface is land.
What does Earth’s surface consist of?
Earth’s surface is mainly covered with liquid water and its atmosphere is is mainly nitrogen and oxygen, with smaller amounts of carbon dioxide, water vapor and other gases.
Where is two thirds of the Earth’s freshwater?
Slightly over two thirds of the fresh water is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater, with only a small fraction present above ground or in the air.
What covers one third of Earth’s surface?
The Pacific Ocean
The Pacific Ocean covers about one-third of Earth’s surface.
How many thirds of the Earth’s surface is covered with water?
About over two thirds of Earth’s surface are covered by water and less than a third of that is taken up by land.
What makes up two thirds of the Earth’s crust?
The oceanic crust covers two-thirds of the Earth’s surface, and makes up the ocean floor. Two types of crust make up the land on Earth and its ocean floor. The crust under land is thicker and contains more rock types.
Which is thicker continental crust or continental crust?
The crust under land is thicker and contains more rock types. The continental crust covers only one-third of the Earth’s surface, and makes up all of the dry land found on Earth.
Which is the thinnest layer of the Earth?
The crust is the thinnest layer of the Earth. It has an average thickness of about 18 miles (30km) below land, and around 6 miles (10km) below the oceans. The crust is the layer that makes up the Earth’s surface and it lies on top of a harder layer, called the mantle.
