We want to STOP the slide from happening

Planting trees and other plants on the hillside will help stop a mudslide. The roots of the plants will help anchor the land in place.

As glaciers move they scrape and pick up rocks. This will cause deep grooves in the soil and over time can create a valley

Dissolving

this word means a chemical reaction is taking place.
