Physical Weathering: ice expanding, wind, rain, frost, thawing, farming, construction, waves

Biological Weathering: tree roots; animals burrowing

Mechanical Weathering: gravity- force of a big rock falling into small rock

chemical weathering: acid rain, oxidation, temperature/heat/pressure/fire, salt wedging (salt expands in cracks in rocks and cracks them)
