Ecology Weathering & Erosion

The breaking down of rocks and other materials on the Earth's surface.

• Erosion

• Deposition

• Exfoliation

The process by which rock and soil are moved from one place to another is called-

• Chemical weatherin

• Erosion

• Mechanical weathering

• Deosition

Which type of area is more likely to weather and erode? An area with a lot of vegetation (plants) or an area with very little? Why?

• The area with very little vegetation, because the roots won't be able to burrow through the rocks to weather it down.

• The area with a lot of vegetation, because the roots will burrow through the rocks causing a landslide.

• The area with very little vegetation, because it has not roots to absorb extra water or hold the soil together. The extra water and loose soil is likely to become a landslide/mudslide.

• The area with a lot of vegetation, because the roots will absorb any extra rain water, and will also hold the soil together preventing a landslide.

The breakdown of rock that results in a change in its chemical composition is called:

• chemical weathering

• mechanical weathering

What type of erosion is dominant in places that are dry with small sediment such as deserts, sea shores and semi-arid regions?

• wind erosion

• water erosion

• mass wasting

• glacier erosion

A tiny groove in soil made by flowing water.

• stream
• gully
• tributary
• rill

• rill
• rain
• runoff
• ground water
