Tectonic plates are a subdivision of Lithosphere. Lithosphere has rigid mechanical properties.
Composition
The earth’s crust is not a homogeneous substance, it has different layers of rocks including sedimentary rocks on top, granitic and metamorphic rocks in the middle and basaltic rocks on the bottom.
Types
These are two types of lithosphere which are given below
- Oceanic: It is associated with oceanic crust and exists in the ocean basins.
