Weathering Review

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

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 other rocks 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

The formation of large cracks in the face of a mountain from ice wedging is an example of:

• mechanical weathering
• chemical weathering

Acid rain wearing away the face of a marble gravestone or statue is an example of?

• mechanical weathering
• chemical weathering

Exposure to rain and oxygen causes the metal minerals in rocks to rust and fall apart.  This is an example of:

• mechanical weathering
• chemical weathering

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

• weathering
• erosion
• deposition
• dumptruck

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

• frost wedging
• acid rain
• permeability
• abrasion
