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.

The surfaces of old concrete statues are often covered with small holes or pits. Which of these MOST LIKELY causes these holes or pits?

• The concrete becomes pitted as water freezes in small cracks in the statue.
• The concrete is chipped away by sand particles blown by strong winds
• The concrete is chemically weathered by acid rain.
• Long exposure to sunlight causes the pits to form.

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

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:

• ice wedging
• acid rain
• permeability
• abrasion

How is mechanical weathering different from chemical weathering?

• Chemical weathering happens over much shorter time frame than mechanical weathering.
• Chemical weathering changes the chemical composition of rocks; mechanical weathering does not.
• Chemical weathering occurs only in tropical climates; mechanical weathering occurs only in cool climates.
• Chemical weathering occurs only in the mountains; mechanical weathering occurs only on flat land.
