Below are the questions for the exam with the choices of answers:
Question #1
A Rockfalls
B Waterfalls
C Mudflows
D Stream capture
E Burrows for marmots
Question #2
A They were carved by the American Indians similar to the large heads you see in Easter Island.
B No one knows why it happens as it only happens here
C The outer surface of the rock fractures into layers running all over the summit and down the sides, which peel. The granite is still being squeezed from the sides and the bottom, which makes the dome shape on the top.
D The outer surface of the rock is full of muscovite which natural curves around other minerals. Rain hits the muscovite and causes it to peel off, which makes the dome shape on the top.
Question #3
A A U shaped basin, the hallmark of a glacial canyon
B A meteorite impact
C A V shaped basin, what the river carved in the past
D Dinosaur fossils
E Nothing, there are no sediments because the glacier removed them
Question #4
A It was not just a moraine, it was shaped in part by a large meteorite impact
B Both A and B
C It is the largest moraine every found on the planet
D It is the oldest moraine found on the planet
E It was not just a moraine, it was a giant dam that caused a flood of icy water, which formed Lake Yosemite
Question #5
A Flowing water that has opened up into a lake, where the sediments could settle.
B Large swamps that formed in a hot, humid location close to the equator.
C Flowing water that has opened up into an inland sea, where the sediments could settle and ocean fossils can be found.
D Frequent landslides that came from the slopes above.
E Polar swamps that formed in proximity to the glaciers.
Question #6
A U Shaped valleys
B Both A and B
C Distinctive scratch marks
D V Shaped valleys
E A series of large, deep lakes
Question #7
A A hot spot volcanic eruption similar to Yellowstone
B Meteorite impact
C River rapids that had treacherous waves. They steepened the walls and caused landslides, giving it the v shape.
D The canyon did not form until the glaciers carved them.
E Volcanic fissure
Question #8
A The dense lower plate was uplifted and formed the Rocky Mountains.
B A huge section is missing. This caused the crust to uplift and tilt.
C The lower plate stabilized at depth and eventually started to slip forming the San Andreas Fault.
D The lower plate sank into the mantle where it was destroyed.
Question #9
A Magma came in and filled all the cracks over and over again, this also formed large crystals.
B Magma came in and metamorphosed the granite over and over again.
C Magma came in and dissolved all the minerals, thus forming small crystals.
D Magma cooled and allowed mud came in and filled all the cracks over and over again.
Question #10
A Small crystals welded together give the rocks a lot of strength.
B The fact that is was metamorphosed by high pressure and temperature.
C The fact it cooled from magma without mud seeping in during formation.
D Large crystals welded together give the rocks a lot of strength.
Question #11
A 10 miles long and 10 miles wide, and 1 miles in depth
B 400 miles long and 60 miles wide, and 5 miles in depth
C 40 miles long and 6 miles wide, and 2 miles in depth
D 100 miles long and 30 miles wide, and 3 miles in depth
E 800 miles long and 90 miles wide, and 7 miles in depth
Question #12
A An asteroid impact
B Glaciers eroding the rocks many times
C A sudden cataclysmic event
D A migration of bison that put so much weight in the valley is slowly dropped
E A long history of the Merced River flooding and eroding down the rocks
Question #13
A By getting the United States Geological Survey to fund his research
B By herding sheep
C By selling paintings of the area
D By getting the National Science Foundation to fund his research
E By selling photographs of the area
Question #14

B Half dome, Yosemite Falls, Angel’s Landing
C Half dome, Niagara Falls, El Capitan
D Half dome, Multinomah Falls, El Capitan
E Half dome, Yosemite Falls, El Capitan
