Chapter 6: Weathering and Erosion - What is Weathering?

Weathering involves reducing landform's mass, while erosion involves moving material to another location. (correct)

Weathering creates soil, while erosion does not affect soil composition.

Weathering only occurs due to chemical processes, while erosion only occurs due to physical processes.

Weathering is a fast process, while erosion is a slow process.

Chemical weathering occurs due to human activities, while physical weathering occurs naturally.

Chemical weathering only affects sedimentary rocks, while physical weathering affects all types of rocks.

Chemical weathering is a fast process, while physical weathering is a slow process.

Chemical weathering involves the breakdown of rock and soil due to interactions with water, acid, and gases, while physical weathering refers to the impact of mechanical or physical processes. (correct)

Carbon dioxide accelerates erosion by moving rocks quickly down slopes.

Carbon dioxide increases soil fertility by providing nutrients to plants.

Carbon dioxide solidifies sedimentary rocks into harder formations.

Carbon dioxide in the air combines with water in the cloud to create acid rain, which dissolves sedimentary rocks. (correct)
