Stacey and her family are hiking in Olympic National Park in the state of Washington. Stacey is pointing out the valleys and explaining how they form. She knows that glaciers are still in the park.
What evidence does Stacey look for to determine whether the valleys were formed by glaciers?
a)
valleys with lots of trees on either side because as the glaciers retreated they deposited seeds picked up from other areas
b)
valleys with lots of fossils in the rock layers because as the glaciers were increasing in size, the ice preserved remains of organisms
c)
valleys that are V-shaped because when the glaciers melted, the flowing water quickly cut down through rock
d)
valleys that are U-shaped because when the glaciers slowly moved through the area they scraped away and smoothed the rock
2.
Which observations about the Rocky Mountains and the Appalachian Mountains would support the claim that exposure to weathering and erosion over time can change landforms?
a)
The Appalachian Mountains are found in the eastern United States and the Rocky Mountains are found nearer the west coast.
b)
The shorter and more rounded Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains.
c)
The length of the Appalachian chain is approximately 2,400 kilometers and the Rocky Mountains chain is about twice as long.
d)
The Appalachian Mountains are composed mostly of sedimentary rocks while the Rocky Mountains also contain other rock types.
3.
Evie is studying sketches of two different volcanoes. Which choice best explains why Volcano A looks different from Volcano B?
