GUYS PLEASE HELP MEEEE!!! On a hike up a mountain Delilah sees small pieces of rock along the trail, the small pieces look like the rock that the mountain is made from. how did these small pieces of rock break off from the mountain?

1. Wind and rain interacted with the rock breaking it into small pieces

2. The small pieces of rock were formed by earthquakes, tsunamis, and other natural disasters. These disasters were strong enough to break the rock into small pieces

3. Rays from the sun shone down on the rock, and it broke into pieces

4. if anything were left out for a long time, it would break into small pieces
