Review for Weathering and Erosion Test
1. How does erosion differ from weathering?
Erosion is the movement of rock. Weathering is the breaking down of rock.
2. What factors determine the rate of weathering?
Climate (how hot and wet)
Type of rock (permeability how many air spaces)
3. __Erosion__ is the movement of rock particles by wind, water, ice or gravity.
4. __Permeability__ means that a material has space that allows water to seep through it.
5. The process that breaks down rock and other materials at Earth’s surface is called __weathering__.
6. The grinding away of rock by other rock particles is called __abrasion__.
7. The process by which ice widen and deepens cracks in rocks is called __freezing and thawing__.
8. Explain deposition in your own words.
After rocks have been weather (broken down) and eroded (moved) deposition is when rock is dropped in a new
spot.

Mechanical
Description
Rock particles wear away rock
Forms from coal, oil and gas burning
(pollution) when combined with rain
Water freezes in cracks in rock and the
crack wide
12. Carbon Doxide
Chemical
Forms carbonic acid when combined with
water and carbon dioxide
13. Water
Chemical
Rounds rocks when in water, due to being
dissolved
14. Oxygen
Chemical
Causes rust to form on some rocks
Shannon
15. Animal Action
Mechanical
Animal tunnels or burrows a hole in solil
16. Describe the results of a rock on the bottom of a flowing river. (Hint: What will eventually happen to the
rock?)
Rock will smooth out and become rounded over time.
17. What is the equation for work?
18. What are the SI units for the following:
Force _Newtons_
Work = Force x Distance
Distance __Meters__
Work _Joules_
19. A 100N girl moves a bench 25 m. How much work is done on the bench?
100 N x 25 m = 2,500 Joules
20. How much work is done if a 40,000 N truck is dragged 10m?
40,000 N x 10 m = 400,000 Joules
21. What type of succession occurs after a forest fire? How long will it take to become a climax community?
Secondary, approximately 150 years
22. How would a continuous rainfall affect a hilly country side where a wildfire previously occurred? Why
would the residence be concerned and what can they do to prevent any further damage?
There would be no plants or grass roots to hold the soil in place and the extra amount of water could result in
a mudslide.
23. What 2 factors determine the difference between the eco-regions of the western and eastern boarders of
Texas? Temperature and precipitation
