Which statement about a young mountain range would be true?

It will be less weathered than older mountain ranges

A stream runs through the mountain erodes differently than a stream through a meadow, why?

The water in the mountains is moving downhill faster

How does water temperature affect the rate of erosion?

warmer water will cause erosion to happen more quickly

Which statement best explains how magma reaches Earth's surface?

Heat and pressure cause the magma to rise
