Question

Which of the following statements about weathering is false?

1) weathering may occur as a result of physical processes that break up rocks into smaller fragments
2) weathering may occur as a result of chemical reactions that dissolve rocks or alter their mineral compositions
3) weathering occurs at or near the surface of the Earth
4) only igneous rocks can undergo weathering
5) landslides are a manifestation of rock weathering

Answer 1

The false statement is that only igneous rocks can undergo weathering.

Step-by-step explanation:

Only igneous rocks can undergo weathering is the false statement among the given options. Weathering can occur as a result of physical processes such as freeze-thaw action or abrasion that break up rocks into smaller fragments. It can also occur as a result of chemical reactions, such as hydrolysis or oxidation, that dissolve rocks or alter their mineral compositions. Weathering occurs at or near the surface of the Earth, where rocks are exposed to various weathering agents. Landslides are a manifestation of weathering because they are caused by the weakening or disintegration of rock due to weathering processes.
