Weathering, Mass Wasting, & Erosion

______ changes the rock, not just in size of pieces but in composition.

• Mechanical Weathering

• Chemical Weathering

The movement of material downslope under the force of gravity.

• Mass Wasting

• Erosion

• Weathering

The more distant removal of material by wind, water, and ice.

• Weathering

• Erosion

• Mass Wasting

The release of overlying pressure cause strips or sheets of rock to peel away.

• Thermal Expansion and Contraction

• Ice Wedging

• Exfoliating

• Biological

Identify the type of Mass Waste represented by this diagram:

• Slide

• Creep

• Slump

• Flow

Breaks apart rocks in areas with temperatures that cycle above and below freezing in the day and night, and also that cycle above and below freezing with the seasons.

• Abrasion

• Biological

• Ice Wedging

• Thermal Expansion and Contraction

Identify the type of Mass Waste represented by this diagram:

• Flow

• Fall

• Creep

• Slide

One rock bumps against another rock.

• Biological

• Ice Wedging

• Exfoliating

• Abrasion

The roots of plants break the rocks apart.

• Biological

• Exfoliating

• Abrasion

• Ice Wedging

_______ breaks rock into smaller pieces. These smaller pieces are just like the bigger rock, just smaller.

• Chemical Weathering

• Mechanical Weathering
