The lithosphere is the rigid outer layer of the Earth that has an average thickness of 75km. It is composed of several plates that move via the process of plate tectonics. The main parts that make up the lithosphere are the crust, mantle, asthenosphere, core, and transition zone. The lithosphere is useful as it serves as a source of minerals, fuels, and supports plant and animal life, with water bodies essential for survival.

1. LITHOSPHERE

2. WHAT IS LITHOSPHERE??
It is the rigid outer layer of earth.
It has an average thickness about 75km
Came from the greek lithos which means rock.
the lithosphere comprises a number of plates
The motion of lithospheric plate is known as
plate tectonics

3. PARTS OF LITHOSPHERE
The five main parts of lithosphere are:
Crust
 mantle
Asthenosphere
Core
Transition zone
There would be no lithosphere if any of
The part is missing
.

4. WHY IS IT USEFUL??
The lithosphere serves as a source of minerals.
It is also the major source of fuels.
Plants and animals grow on lithosphere.
It has water bodies which are essential for
survival.
