Question

how do rivers and streams shape the land?
○ through volcanic eruptions
○ by compacting the land through pressure
○ by chemical reactions
○ by wearing away rock and soil through erosion

Explanation:

Rivers and streams carry water which has the force to wear away rock and soil over time through the process of erosion, thus shaping the land. Volcanic eruptions are related to volcanic activity, compacting land through pressure is not a main way rivers/streams shape land, and chemical reactions are not the primary mechanism for how they shape the land.

Answer:

By wearing away rock and soil through erosion
