1

Frost action or ice wedging is when __________ gets into the __________ and the temperature drops __________ into __________. This form of water __________ and __________ the rock.

1

Exfoliation is when rock __________ (or grows) and __________ (or shrinks) because the __________ are __________.

1

Root wedging is when the _______ of plants grow into the _______ of rocks.

1

Place the term in the correct location. Then fill in your personal flow chart paper.

Other Answer Choices:

Ice Wedging - freezing/thawing of ice cracks rock

Root Wedging - plant roots growing into rocks

Abrasion - grinding of rock against rock

Exfoliation - alternating hot/cold cracks rocks

1

Oxidation is the formation of _______ when the element _______ is exposed to _______ .

1

Oxidation happens because there is iron in some rocks and oxygen in the water or air makes it react.

1

Carbonation happens when __________ flows through the soil to create a __________ called __________.

Place the term in the correct location. Then fill in your personal flow chart paper.

Other Answer Choices:

Oxidation (Iron + Oxygen = Rust)

Carbonation (Acid rain dissolves limestone and makes caves)

1

Climate's impact on weathering has to do with average yearly _______ (in Fahrenheit or Celsius) and average yearly _______ (rain/snow).

1

Softer rock has a relatively higher hardness level and therefore is more resistant to weathering.

1

The more surface area of rock exposed, the higher the rate of weathering on that rock.
