Weathering Erosion Deposition

Which of these is most likely to experience oxidation?

• Bicycle tire

• An automobile

• Wooden fence

• Tennis ball

The picture above shows the process of physical weathering that can cause cracks in rocks in Georgia’s northern mountains to widen. What is this process called?

• Abrasion

• Dissolution

• Ice wedging

• Oxidation

Which of the following cannot cause physical/mechanical weathering?

• Water

• Acid

• Wind

• Animals

How does air chemically weather rock away?

• The air molecules are abrasive.

• Air fills cracks in the rock and later expands, causing the cracks to enlarge.

• The oxygen in the air combines with iron in a rock in a process called oxidation.

• The rock cracks after absorbing too much oxygen in a process called acid rain.

As I fell off the mountain, I caused a rockslide. There were hundreds of rocks, large and small, rolling down the mountain. We were bumping into each other and sliding all over. It was a regular rock stampede! What type of weathering is being described above?

• Physical weathering caused by ice wedging

• Physical weathering caused by gravity

• Chemical weathering caused by reactions with acid precipitation

• Chemical weathering caused by acids in living things

Looking at the picture above, which of the following types of chemical weathering causes stalagmites in a cave?

• Reaction with oxygen

• Reactions with acid precipitation

• Reactions with acids in groundwater

• Reactions with acids in living things

In the picture above, what type of weathering does this prairie dog cause?

• Chemical weathering by creating weak acids that weather the soil

• Physical weathering by causing rocks to fall and hit other rock

• Chemical weathering by creating huge cracks with their claws

• Physical weathering caused by burrowing through the soil

I stopped at the base of the mountain, on top of the pile of rocks. I spent many years there, and gradually, a colony of lichen began to grow on my side. They were easy to live with a lot of iron, and the iron helped to cause their red orange color. What type of weathering is being described?

• Chemical weathering reactions with oxygen

• Chemical weathering reactions with acids in groundwater

• Physical weathering caused by pressure

• Chemical weathering reactions with acid in living things

Ice, wind, water, gravity, plants, and animals are all agents of

• differential weathering.

• oxidation.

• physical weathering.

• desertification.

Use the image below to answer the question. The sculpture on the left is a photo from 1908 and the photo on the right was taken in 1968. There are statues made of sandstone found in Westphalia, Germany that have been weathered severely. What type of weathering caused this to change?

• Physical weathering caused by abrasion

• Chemical weathering caused by acids in groundwater

• Chemical weathering caused by acids in living things

• Chemical weathering caused by reactions with acid rain
