$200 Answer from H3 ice, wind, water, gravity, plants and animals
$300 Question from H3 An agent of mechanical weathering that causes rocks to fall (rock slide/landslide) causing abrasion as they hit each other
$300 Answer from H3 Gravity
$400 Question from H3 When water seeps into cracks during warm weather, temperatures drop, water freezes and expands pushing against the sides of the crack (pressure), widening the crack until the rock breaks up/apart
