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.

A.   Magma came in and filled all the cracks over and over again, this also formed large crystals.

B.   Magma came in and dissolved all the minerals, thus forming small crystals.

C.   Magma cooled and allowed mud came in and filled all the cracks over and over again.

D.   Magma came in and metamorphosed the granite over and over again.

A.   The lower plate stabilized at depth and eventually started to slip forming the San Andreas Fault.

B.   The lower plate sank into the mantle where it was destroyed.

C.   The dense lower plate was uplifted and formed the Rocky Mountains.

D.   A huge section is missing. This caused the crust to uplift and tilt.

A.   Volcanic fissure

B.   The canyon did not form until the glaciers carved them.

C.   A hot spot volcanic eruption similar to Yellowstone

D.   Meteorite impact

E.   River rapids that had treacherous waves. They steepened the walls and caused landslides, giving it the v shape.

A.   A series of large, deep lakes

B.   Both A and B

C.   V Shaped valleys

D.   U Shaped valleys

E.   Distinctive scratch marks

A.   Flowing water that has opened up into a lake, where the sediments could settle.

B.   Flowing water that has opened up into an inland sea, where the sediments could settle and ocean fossils can be found.

C.   Polar swamps that formed in proximity to the glaciers.

D.   Large swamps that formed in a hot, humid location close to the equator.

E.   Frequent landslides that came from the slopes above.

A.   It is the largest moraine every found on the planet

B.   It was not just a moraine, it was shaped in part by a large meteorite impact

C.   It was not just a moraine, it was a giant dam that caused a flood of icy water, which formed Lake Yosemite

D.   It is the oldest moraine found on the planet

E.   Both A and B

A.   Nothing, there are no sediments because the glacier removed them

B.   A meteorite impact 

C.   A U shaped basin, the hallmark of a glacial canyon

D.   A V shaped basin, what the river carved in the past

E.   Dinosaur fossils

A.   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.

B.   They were carved by the American Indians similar to the large heads you see in Easter Island.

C.   No one knows why it happens as it only happens here

D.   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.

A.   Mudflows

B.   Waterfalls

C.   Stream capture

D.   Rockfalls

E.   Burrows for marmots
