Answer 2

Answer:

Tectonic Plates are three type.

1. Convergent Boundary

2. Divergent Boundary

3. Transform Boundary

Explanation:

1.convergent boundary- when two plates move towards each other due to sinking of convection current .

2. divergent Boundary- when two plates move away from each other due to rise of convection current is called divergent or construction boundary .

3. transform Boundary - when two plates coming together they may either colloid and crumble or one may slide under the other at times , they may also move horizontally past each other and form transform Boundary.
