Planet Earth contains three compositional layers- CORE‚ MENTLE & CRUST. Core: At the centre is the densest of the three layers‚ the core. The core is a spherical mass‚ composed largely on metallic iron‚ with lesser amount of nickel and other elements. Mantle: The thick shell of dense‚ rocky matter that surrounds the core is mantle. The mantle is less dense than the core but denser than the outer most layer‚ the crust. Crust: Above the mantle lies the thinnest and outermost layer‚ the crust

lies above the troposphere between 11-30 miles; it filters out the sun’s harmful radiation. The hydrosphere consists of earth’s water‚ found in liquid water‚ ice‚ and water vapor. The lithosphere is the crust and upper mantle of the earth’s soil. It contains nonrenewable fossil fuels‚ minerals‚ and soil‚ and renewable soil chemicals needed for plant life. The biosphere includes most of the hydrosphere‚ parts of the lower atmosphere and upper lithosphere. All parts of the biosphere are interconnected
