Erosion Flashcards
1
Q
Attrition
A
Waves smash rocks and pebbles on the shore into each other, and they break and become smoother
2
Q
Abrasion
A
Bits of rock and sand in waves grind down cliff surfaces like sandpaper.
3
Q

Air may become trapped in joints and cracks on a cliff face. When a wave breaks, the trapped air is compressed which weakens the cliff and causes erosion
4
