What is the process that breaks down rock through chemical changes?
What are the two most important factors that determine the rate at which weathering occurs?
type of rock and climate
In what climate will weathering occur the fastest?
hot and wet
What is the name given to weathering that occurs as a result of repeated freezing and thawing of water? Double your points if you can tell me the type of weathering this is.
frost wedging; mechanical
What do we call weathering that occurs as a result of oxygen reacting with water and iron? Double your points if you can tell me the type (mechanical or chemical) of weathering.
What is the type of weathering that occurs when feldspar turns to clay? Double your points if you can tell me the type of weathering.

What do weathering, erosion, and deposition have in common? Add 200 points if you can name more than one similarity.
shape and change Earth’s surface; part of a cycle; all have to do with sediment
How can weathering, erosion, and deposition happen at the same time? Add 500 points if you can describe a situation that involves more than two.
Examples: Wind (erosion, abrasion, deposition) Water (weathering, erosion, abrasion, deposition) Waves (abrasion, erosion, deposition) Glaciers (erosion, abrasion, deposition)
