What are the 3 major types of plate boundaries and what happens at each?

Answer 1

1/ Convergent, or colliding:-where the plates are moving towards each other.

Example : Nazca plate colliding with west coast of South America produces the Andes mountain range.

2/ Divergent, or spreading:- where the plates are moving apart.

Example:- Mid Atlantic sea floor spreading causing the USA to move away from Europe.

3/ Transform ,or sliding:- where the two plates slip past each other.

Example:- San Andreas fault where the Pacific plate is moving North causing earthquakes as the stored energy is rapidly released in the stick and slip motion.

Answer 2

The three major types of plate boundaries are divergent boundaries, where plates move apart, resulting in mid-ocean ridges; convergent boundaries, where plates collide, leading to subduction zones or mountain formation; and transform boundaries, where plates slide past each other, causing earthquakes along faults.
