Bobby observed that a metal trash can was covered with rust. What type of weathering caused the rust on the trash can?

• Physical weathering

• Wind weathering

• Chemical weathering

• Erosion weathering

What is likely to cause cracks on the sidewalk?

• Repeated freezing and thawing of water
• Tree roots or plant roots growing bigger
• Both and A and B
• Neither A or B

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.

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

• Physical weathering

The natural chemical or physical processes that breaks down rock on Earth's surface.

• weathering
• erosion
• deposition
• jackhammering

The process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.

• weathering
• erosion
• deposition
• dumptruck

These rocks were made smooth by wind blowing smaller rock particles across their surface.  This is an example of:

• ice wedging
• chemical weathering
• acid rain
• abrasion

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 are canyons formed?

• Wind blows sand into high piles, which form the canyon walls.
• Rivers erode soil and rock over time, leaving behind canyon walls.
• Gravity causes rocks to fall from mountain sides onto valley floors.
• Ice freezes and thaws in cracks of rocks, and the cracks become canyons.
