The natural chemical or physical processes that breaks down rock on Earth's surface.

• weathering

• erosion

• deposition

• jackhammering

The process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.

• weathering

• erosion

• deposition

• dumptruck

This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

• mechanical weathering

• chemical weathering

• erosion weathering

• deposition

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.

• mechanical weathering

• chemical weathering

• erosion weathering

• deposition

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:

• ice wedging

• acid rain

• permeability

• abrasion

Weeds growing into the cracks in a sidewalk and the sidewalk begins to crumble is an example of:

• mechanical weathering

• chemical weathering

Potholes forming in the road after a cold winter is an example of:

• mechanical weathering

• chemical weathering

A metal statue slowly turning green after years of being outside is an example of:

• mechanical weathering

• chemical weathering

Rocks along a riverbed that are smoothed from continuously moving water and sediment rubbing against them is an example of:

• mechanical weathering

• chemical weathering

A piece of sandstone changing color (from brown to rusty red) from exposure to water and air is an example of:

• mechanical weathering

• chemical weathering
