It contains three quarters of the mass of earth’s atmosphere. The main constituents of the troposphere are nitrogen, oxygen, carbon dioxide, traces of argon, hydrogen , ozone and other gases. The clouds are present in the troposphere because it ...
3.1 Earth’s Layers: Crust, Mantle, and Core
Web3 dec. 2024 · The mantle is a layer of semi-solid rock that lies between the Earth's thin crust and its liquid outer core. The mantle is approximately 2,900 kilometers (1,800 miles) thick and makes up about 84% of the Earth's total volume. The crust, mantle, and core are the three coatings of the Earth. The crust is made up of minerals and solid rocks. WebFig. No. 2: Structure of Earth Crust. Crust is the thinnest outermost layer of the Earth. It is known as lithosphere. Crust makes up 0.5-1.0% of the Earth’s volume and less than 1% of Earth’s mass.
