Question

There are four main types of mechanical weathering: frost wedging in which rocks are broken by water freezing within cracks, salt crystal growth in which rocks are broken by salt freezing within cracks, sheeting in which rocks dome upward and peel off, and biological activity in which living things such as tree roots break rocks apart.

Answer 1

Explanation:

Types of Mechanical Weathering:

Frost Wedging - water expands when it freezes. This photograph shows the individual layers within the sedimentary rock breaking apart through repeated cycles of freeze-thaw. ... Exfoliation is very common whenever plutonic igneous rocks are exposed.
