Question

when pieces of the earths surface collide or push together, what is formed?
a crack
mountains
a wreck
valleys

Explanation:

When tectonic plates (pieces of the Earth's surface) collide or push together, the immense pressure causes the crust to fold, uplift, and stack, leading to the formation of mountains over long - term geological processes. Cracks are more likely due to pulling apart forces, a wreck is not a geological term for this process, and valleys are often formed by erosion or rifting, not by colliding and pushing together forces.

Answer:

B. mountains
