Agents of Weathering

Ice, wind, water, gravity, plants, and animals are ALL causes of:

• chemical weathering
• mechanical weathering
• oxidation
• mass movement

If you drop a piece of chalk into a cup of vinegar, the chalk will fizz and dissolve after a few minutes. This process is an example of:

• chemical weathering
• differential weathering
• mechanical weathering
• infiltration

When oxygen in the air reacts with iron and water, the result is: 

• abrasion
• differential weathering
• oxidation
• infiltration

Which of the following areas would be most strongly affected by wind erosion?

• desert
• pine forest
• rocky beach
• grassland

What is it called when wind blows sand and silt against exposed rock, eventually wearing away the rock's surface?

• erosion
• abrasion
• chemical weathering
• oxidation

All of the following are agents of erosion EXCEPT

• wind
• glaciers
• gravity
• sunlight

What is it called when forces of nature such as wind or ice break apart rocks into sediments?

• deposition
• oxidation
• erosion
• weathering

What is an enormous mass of ice moving over land?

• glacier
• iceberg
• ice wedging
• dune

If acids in plants, such as lichens, react with the minerals in rocks to weaken them, what is this an example of?

• mechanical weathering
• oxidation
• chemical weathering
• erosion

The process where water seeps into the cracks of rocks and freezes and thaws breaking the rock apart.

• ice wedging
• slump
• creep
• oxidation
