Rocks can be broken down in a variety of ways through the process of weathering. Which of the following is an example of a chemical form of weathering?

Plants grow on rocks and their roots grow into the cracks of the rock, breaking it apart. 

Water enters into the cracks of a rock and, as it freezes and becomes ice, expands to break the rock in a process called wedging. 

The wind blows sand which slowly wears down the face of a rock in the process called abrasion. 

Acidic water seeps into the cracks of limestone causing a reaction with the rock and creating holes in it.

Lori is learning about two parts of the rock cycle. Weathering and erosion. She needs to explain how weatehring and erosion are different. Which of the following correctly describes the difference between weathering and erosion?

Weathering is the movement of rocks by wind, erosion is the movement of rocks by water.
