Presentation Transcript

  1. 1. Why is water a major agent of chemical weathering?A. Because water cools the surroundings when itevaporates.B. Because water dissolves many of the minerals thatmake up rocks.C. Because water has a density of about 1 gm/cm3.D. Because water has the highest specific heat of all common Earth materials

  2. 2. Of the various types of mass movements, which isthe slowest acting?A. rock slidesB. debris flowsC. slumpD. creep

  3. 3. In which climate would the chemical weathering of limestone occur most rapidly?A. Cold and dryB. Cold and humidC. Warm and dryD. Warm and humid

  4. 4. What is the primary force responsible for most of thetransportation of rock material on the surface of Earth?A. gravityB. windC. running waterD. glacial ice

  5. 5. How do glaciers erode the land?A. Through plucking and abrasion.B. Through wind and waves.C. Through gravity and waves.D. Through permeability and porosity.

  6. 6. How does the mass movement called slump occur?A. An entire piece of rock and soil breaks loose andsurges downhill.B. A river carries away sediments.C. The wind blows very hard.D. Glaciers push the land forward.

  7. 7. What are two landforms created through winddeposition?A. Glacial lakes and oxbow lakesB. Sand dunes and loess depositsC. Meanders and cutoffsD. U-shaped valleys and V-shaped valleys

  8. 8. Why are slides the most devastating form of mass movements.A. Because they happen on hills.B. Because of the tremendous energy they get from their high speeds.C. Because people live near them.D. Slides are not the most devastating form of mass movements, creep is.

  9. 9. As the speed of a river increases, what happens to the size of the sediment particles that it can carry?A. As speed increases, particle size increases.B. As speed increases, particle size decreases.C. As speed increases, there is no change in the size of particles that are transported.D. It is not possible to tell what happens to particle size when the river speed increases.
