Plants usually break open small cracks in rocks with their

• seeds

• roots

• branches

• pollen

Lichen secretes an acid that breaks down rock.

• Mechanical Weathering

• Chemical Weathering

3 Examples of erosion (movement of rock particles) include

• wind, water and gravity carrying sediment

• alluvial fans sitting on land and deltas piled up in the water

• mudslides, landslides, and creep

• stalactites and stalagmites found in a cave

• deflation and saltation

3 examples of

DEPOSITION

(rock particles settle/stop/are deposited)

• Alluvial fans and deltas

• stalactites and stalagmites

• sand dunes, sand bars, barrier islands

• wind, water and gravity

• creep, ocean waves, sandblasting

The extremely slow (the slowest) mass movement of material down a slope is called

• mudslides

• creep

• mudflow

• avalanche

Which  could contribute to acid precipitation (acid rain)? Pick 2.

• abrasion and all forms of oxidation

• root wedging and animal burrowing

• hurricanes and tornadoes

• volcanoes

• burning fossil fuels
