How do big mountain ranges form? Select one:

Over time, from rivers depositing small pieces of rock in the same location.

Over time, from the earth’s plates pushing on each other.

Suddenly, from a volcanic eruption.

Suddenly, from a single, massive earthquake.

Mountain ranges often appear on the edges of continents. The earth would of had to smash together to make the land go up into the air. A mountain range or a hill range is a series of mountains and/or hills arranged in a line and connected by high round. Mountain ranges are a result, in most cases, of a geological process called a plate tectonics, which is the motion of large plates, like continents. This theory that supports the concept of continents colliding, explains why there are mountain ranges.

So the answer is B: Over time, from the earth's plates pushing on each other.

The answer is Over time, from the earth’s plates pushing on each other

Explanation:

The worlds tallest mountain ranges form when the pieces of the earth's crust called plates smash against each other in a process called plate tectonics.
