To solve this worksheet, we need to sort the eight pictures into two categories:
Weathering and
Erosion.
Here is the simple rule provided in the hint:
*
Weathering: If the rock is
breaking or cracking in place.
*
Erosion: If the rock, dirt, or sand is
moving from one place to another.
Let's look at each picture one by one:
1.
"The roots of the tree caused the rock to crack."
* The rock is splitting apart because of the roots. It is breaking.
*
Category: Weathering
2.
"The mud is moving the rocks down."
* The key word here is "moving." The rocks are being carried away.
*
Category: Erosion
3.
"The rain washed away the dirt."
* "Washed away" means the dirt is moving.
*
Category: Erosion
4.
"Water got into the crack of a rock and when the water froze, the rock cracked."
* This is called ice wedging. The rock is cracking/breaking due to the ice.
*
Category: Weathering
5.
"The wind is carrying the sand away."
* "Carrying... away" means the sand is moving.
*
Category: Erosion
6.
"The canyon is smooth because of the ocean water."
* The water is wearing down the rock to make it smooth. This is a type of breaking down (abrasion).
*
Category: Weathering
7.
"The hurricane caused the rocks to break into tiny pieces."
* The rocks are breaking into smaller pieces.
*
Category: Weathering
8.
"The river is carrying the products downhill."
* "Carrying" means the material is moving.
*
Category: Erosion

Final Answer:
Weathering (Breaking down):
* The roots of the tree caused the rock to crack.
* Water got into the crack of a rock and when the water froze, the rock cracked.
* The canyon is smooth because of the ocean water.
* The hurricane caused the rocks to break into tiny pieces.
Erosion (Moving):
* The mud is moving the rocks down.
* The rain washed away the dirt.
* The wind is carrying the sand away.
* The river is carrying the products downhill.
