Decreased temperature
Increased Evaporation
Many processes that shape Earth happen over thousands of years. Some processes happen much more quickly. Which of the following has the potential to change Earth's landforms quickly?
The carving of a valley by a glacier
The formation of a canyon by a river
The erosion of sand on a beach by storms
The weathering of rocks by wind
Which type of stream is most likely to cause the greatest amount of erosion?
A slowly moving stream with a small amount of water.
A quickly moving stream with a small amount of water.
A quickly moving stream with a large amount of water.
A slow moving stream with a large amount of water.
On a recent field trip to a local river, the science class collected several rocks from the river bed. The rocks were all smooth and rounded. Why were the rocks in the river bed smooth?
Rushing water in the river wore away any jagged edges.
The minerals from which the rocks are made cannot form jagged edges.
Over centuries, the action of the wind caused the rocks to become smooth.
Plants along the river released substances that mixed with the water to smooth the rocks.
Hailey and her brother made a sand castle at the beach. Hailey slowly poured water on top of the sand castle. Some of the sand ran down the side of the castle with the water. What type of phenomenon did Hailey demonstrate?
Weathering by temperature change.
Erosion by heat.
Weathering by water.
Erosion by water.
Which of the following is not an example of erosion?
The wind blowing sand from one sand dune to another.
Water carrying sediment down a long bending river.
Water getting into a rock and cracking the rock when it freezes.
An avalanche caused by gravitational force.
When areas of uneven elevation get heavy rains, landslides can form. Landslides are most likely to form
in areas that have temperatures close to freezing.
in regions with dense rock under the soil layer.
on the tops of very tall mountains.
on the slopes of very steep hills.
How does erosion compare to physical weathering?
Both break down materials.
Erosion breaks down materials, and weathering carries them from place to place.
Weathering breaks down materials, and erosion carries them from place to place.
Both move materials from place to place.
