Lithosphere:-
The lithosphere is the solid outer part of the Earth. It includes the crust and the uppermost mantle, which constitute the hard and rigid outer layer of the Earth. The lithosphere composed of rocks that form the solid covering of the Earth's crust. The rocks which form the outermost thin layer of the earth are made up of minerals. The crust covers the entire surface of the earth and the beds of seas and oceans. The lithosphere is the home of humans and all the plants and animals that live on land. The lithosphere has many types of landforms.
Hydrosphere:-
Hydrosphere is the sphere of water. It includes water in every place and every form on earth. It plays a key role in the water cycle of the earth. It provides fresh water. The hydrosphere is home to numerous aquatic animals. It covers nearly 71 percent of the Earth's surface, hence the earth is known as a blue planet. It includes oceans, rivers and lakes on the surface of the earth.
