Question 51 pts
Which human behavior causes erosion by building roads and laying concrete?
Group of answer choices

agriculture

urbanization

deforestation

climate change

Answer 1

1) physical biological weathering — animals physically wear down rock (biological + mechanical)

2) water freezing and thawing in rock crevices — freeze–thaw is physical weathering

3) Weathering breaks rock into small pieces. — that's the first step

4) Erosion moves materials. — transport follows breakdown

5) urbanization — building roads and concrete causes erosion through urban development
