discharge
erosion
weathering
- 17. Multiple Choice
Which of the following conditions is necessary for dunes to form?
heavy rains
strong winds
low humidity
high temperatures
- 18. Multiple Choice
How does chemical weathering differ from physical weathering?
Human activity causes chemical weathering but does not cause physical weathering
Chemical weathering does not break rocks down into smaller parts, but physical weathering does
Chemical weathering is acid precipitation and pressure, and physical weathering is wind and temperature changes
Chemical weathering happens when the bonds that hold minerals together break; physical weathering happens when physical actions wear away and crack the rocks
