This type of weathering involves changes that some substances can cause in the surface of the rock that make it change shape or color
What is chemical weathering?
This layer is hot and moves like liquid
What is the asthenosphere?

What is the crust?
This cracks and breaks rocks apart
What is ice?
A vent or rupture in the Earth's crust from which hot rock, steam, and gases erupt
