Over millions of years, the shape of mountains on Earth's surface can change to low hills and then rolling plains. These changes are most likely caused by-

• Folding and faulting

• Volcanoes and Earthquakes

• Human activity

• Weathering and Erosion

A student wanted to demonstrate weathering and erosion. The student put the same number/size of rocks into 2 tin cans, then added a small amount of water to both cans. Can A was shaken at a constant rate for 15 minutes, and can B was shaken for 60 minutes. The student then drained out all of the water and placed the rocks on the desk to observe. What is the best prediction of how how the rocks will look after this experiment?

• The rocks in can B will become larger and rounder than can A

• The rocks in can B will become smaller and rounder than can A

• The rocks in can A will become smaller and rounder than can B

• The rocks in can A will become Larger and rounder than can B

What is the difference between weathering and erosion?

• Erosion breaks down the rocks, and weathering carries the broken pieces away.

• Erosion carries broken pieces away, and weathering builds the pieces back up into another land mass.

• Weathering carries broken pieces away, and erosion builds the pieces back up into another land mass.

• Weathering breaks down rocks, and erosion carries the broken pieces away.

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

• Chemical weatherin

• Erosion

• Mechanical weathering

• Deosition

This type of weathering in which rock is physically broken into smaller pieces.

• Chemical weathering

• Erosion

• Mechanical weathering

• Deposition

What do we call the process in which rock is broken down by changes in its chemical makeup.

• Chemical weathering

• Mechanical weathering

• Erosion

• Deposition

The grinding/scratching away of rock by other rock particles carried in water, ice, or wind

• Frost wedging

• Exfoliation

• Oxidation

• Abrasion

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.
