Chemical Weathering and Soils

Chemical Weathering Directions: Read the passage. Chemical Weathering is a process that breaks down rock through chemical changes. This type of weathering.

Remember: Weathering is… the breaking down of rocks There are two types of weathering: mechanical weathering & chemical weathering. Weathering happens.
