Below are the questions for the exam with the choices of answers:
Question #1
A Burrows for marmots
B Rockfalls
C Stream capture
D Waterfalls
E Mudflows
Question #2
A 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.
B 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.
C No one knows why it happens as it only happens here
D They were carved by the American Indians similar to the large heads you see in Easter Island.
Question #3
A Dinosaur fossils
B A V shaped basin, what the river carved in the past
C A meteorite impact
D Nothing, there are no sediments because the glacier removed them
E A U shaped basin, the hallmark of a glacial canyon
Question #4
A It is the oldest moraine found on the planet
B It was not just a moraine, it was a giant dam that caused a flood of icy water, which formed Lake Yosemite
C It was not just a moraine, it was shaped in part by a large meteorite impact
D Both A and B
E It is the largest moraine every found on the planet
Question #5
A Frequent landslides that came from the slopes above.
B Flowing water that has opened up into an inland sea, where the sediments could settle and ocean fossils can be found.
C Flowing water that has opened up into a lake, where the sediments could settle.
D Polar swamps that formed in proximity to the glaciers.
E Large swamps that formed in a hot, humid location close to the equator.
Question #6
A U Shaped valleys
B Distinctive scratch marks
C Both A and B
D V Shaped valleys
E A series of large, deep lakes
Question #7
A River rapids that had treacherous waves. They steepened the walls and caused landslides, giving it the v shape.
B A hot spot volcanic eruption similar to Yellowstone
C Volcanic fissure
D The canyon did not form until the glaciers carved them.
E Meteorite impact
Question #8
A The lower plate sank into the mantle where it was destroyed.
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 dense lower plate was uplifted and formed the Rocky Mountains.
Question #9
A Magma came in and dissolved all the minerals, thus forming small crystals.
B Magma came in and metamorphosed the granite over and over again.
C Magma cooled and allowed mud came in and filled all the cracks over and over again.
D Magma came in and filled all the cracks over and over again, this also formed large crystals.
Question #10
A The fact it cooled from magma without mud seeping in during formation.
B The fact that is was metamorphosed by high pressure and temperature.
C Large crystals welded together give the rocks a lot of strength.
D Small 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 800 miles long and 90 miles wide, and 7 miles in depth
C 400 miles long and 60 miles wide, and 5 miles in depth
D 40 miles long and 6 miles wide, and 2 miles in depth
E 100 miles long and 30 miles wide, and 3 miles in depth
Question #12
A A long history of the Merced River flooding and eroding down the rocks
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 An asteroid impact
Question #13
A By selling paintings of the area
B By getting the National Science Foundation to fund his research
C By herding sheep
D By selling photographs of the area
E By getting the United States Geological Survey to fund his research
Question #14
A Half dome, Yosemite Falls, Angel’s Landing
B Half dome, Multinomah Falls, El Capitan
C Half dome, Niagara Falls, El Capitan
D Half dome, Yosemite Falls, Redwoods
E Half dome, Yosemite Falls, El Capitan
