Question

question 4.
what natural process is shown in linda’s model?
a. physical weathering
b. biological weathering
c. wind weathering
d. chemical weathering

Explanation:

The model shows water in rock cracks exerting outward pressure (freeze-thaw action), which breaks rocks apart without changing their chemical composition. This is a type of physical weathering. Biological weathering involves living organisms, wind weathering is driven by wind abrasion, and chemical weathering alters rock chemistry, none of which match the diagram.

Answer:

A. physical weathering
