While hiking last year, Mike saw a large boulder next to a mountain trail. The boulder had no cracks. While hiking on the trail
this year, he saw two large cracks in the boulder. Which of the following most likely caused these cracks to form?
Shaking from high winds.
Pressure from flowing water.
Erosion due to falling rain and snow.
Weathering due to freezing and thawing.

The reason that caused these cracks to form is weathering due to freezing and thawing.
Weathering simply means the breaking down of rocks. In this situation, the boulder is freezed and thawed and due to this, as time progresses, it'll gradually be broken down. This is the reason why Mike saw the cracks even though there were no cracks the last time he went hiking.
the air molocules that are surrounding the metal will speed up, and the molocules in the metal will slow down, because as the metal cools the molocules will cool which would make them slow down, but then it would heat the surrounding air and make those molocules speed up.
