Which is a result of boundary plates colliding or sliding past each other?

Question

1.valleys form
2.volcanoes erupt
3.mountains form
4.earthquakes occur

Answer 1

The correct result of boundary plates colliding or sliding past each other is:

4. earthquakes occur

While the collision of tectonic plates can also lead to the formation of mountains (option 3), the most direct and immediate result of these interactions, especially in cases of sliding past one another (transform boundaries), is the occurrence of earthquakes.
