A student hiking in a rock area on a mountain notices that wide, deep cracks have formed in some of the large rocks. Some of the cracks are so large that the rocks have broken apart. Which process most likely caused these rocks to crack and creak? 

• Erosion by wind
• Water freezing and thawing
• Erosion by fast-moving
• Sediments being deposited.

What is the weathering process in which rocks are broken down into smaller pieces (sediments) and do not change the rock composition?

• Acid weathering 
• Gravity weathering
• Chemical weathering
• Mechanical weathering

Which of the following is the most important agent of chemical weathering to form this cave?

• Water - It can carry acid and dissolve rock
• Erosion - Moves the rocks from one place to another
• Wind - It displaces rocks
• Exfoliation - New cracks give chemical reactions the chance to operate
