Below are the questions for the exam with the choices of answers:
Question #1
A It could be tomorrow or 10 to 100 thousand years from now. We cannot really tell
B Not for 2 million years
C
D Not for 10 million years
E The magma is cooling so fast it no longer can erupt
F Not for 200,000 years
Question #2
A So much human trash is causing the lake level to change
B Isostatic rebound
C No one knows right now
D The magma chamber is rising and pushing the ground up
E Sediment is piling up quickly causing the lake floor to sink
Question #3
A Isostatic rebounding is allowing the lake to rise as the glaciers melt
B Carbon dioxide is released into the lake preventing any fish from living in it
C Subsidence, the lake floor is sinking
D Uplift, you can now see a sunken boat on the surface
Question #4
A Toxic gas killed off 60% of the park’s wildlife
B More than 500 earthquakes in 10 days
C Yellowstone erupted
D Yellowstone rose over 3 feet in elevation
Question #5
A It shows that the North American plate is moving
B It shows that the volcanic hot spot is shifting to the left
C It shows that pressure has been relieved in the volcano making an eruption unlikely to happen in the future
D It shows that the pressure has increased making an eruption likely in the next ten years
Question #6
A 150,000 years
B 800,000 years
C A few million years
D 1000 years
E 50,000 years
Question #7
A The crater of Yellowstone formed because there was a giant reservoir of molten rock, which when lava erupted, the ground around collapsed and fell through
B Yellowstone crater formed from a meteor impact that killed off the Ice Age mammals
C By basalt flows down cutting the slopes of the volcano
D By subsidence caused by the piling up of heavy rock

D Volcanic ash from last Yellowstone super eruption, 640,000 years ago
Question #10
A Basalt
B Rhyolite
C Sandstone
D Limestone
E Granite
Question #11
A Glacial deposits from the north
B Hot molten lava flow originating from deep below the earth crust, slow cooled and making its way towards the surface.
C Erosion of old granite rock units
D Metamorphism of old beach deposits due to the high temperature of the hot springs
Question #12
A Glacial melt water continually fills the basin, hot rock heat the water, water pressure drops, and then thousands of gallons of water turn to steam and blast into the air.
B Rainwater continually fills the basin, hot rock heat the water, water pressure drops, and then thousands of gallons of water turn to steam and blast into the air.
C It is actually not faithful but erupts irregularly.
D River water slowly fills the reservoir under the crust and heats up with hot rock underneath.
Question #13
A It is home to the largest diversity of wildflowers
B Its strange geology
C It sinks a more than a foot per year causing groundwater to shoot to the surface
D Its large animals can only live at its 8,000 foot elevation
