Explanation:
LITHOSPHERE - DEFINITION
Lithosphere is the solid crust or the hard top part of the Earth. It is made up of rocks and minerals and covered with a thick layer of soil. It is not a smooth surface as you see on the globe but has high mountains, plateaus or high lands, low plains, deep valleys and very deep basins which are filled with water (oceans).
ATMOSPHERE - DEFINITION
It is one of the four components of the Earth's ecosystem (the other three are biosphere, hydrosphere, and lithosphere). It is a band of gases enveloping the Earth's surface. Ninety-nine percent of its mass is concentrated within 20 miles of the earth's surface.
HYDROSPHERE - DEFINITION
All the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds.
BIOSPHERE (HYDROSPHERE, LITHOSPHERE AND ATMOSPHERE) - DEFINITION
Hydrosphere, atmosphere and lithosphere of earth together constitute the biosphere.
Hydrosphere- It is the part of earth covered by 71% of water. Water is essential for supporting life's existence.
Lithosphere- The surface of the earth is called as lithosphere. It supports the growth of microorganisms, plants and animals.
Atmosphere- It is a mixture of gases that surrounds the earth. 78% of the atmosphere is nitrogen, 21% is oxygen and rest 1% consists carbon dioxide, argon and other gases.
