Below are the questions for the exam with the choices of answers:
Question #1
A Not for 10 million years
B
C The magma is cooling so fast it no longer can erupt
D Not for 200,000 years
E It could be tomorrow or 10 to 100 thousand years from now. We cannot really tell
F Not for 2 million years
Question #2
A Sediment is piling up quickly causing the lake floor to sink
B So much human trash is causing the lake level to change
C Isostatic rebound
D No one knows right now
E The magma chamber is rising and pushing the ground up
Question #3
A Subsidence, the lake floor is sinking
B Uplift, you can now see a sunken boat on the surface
C Carbon dioxide is released into the lake preventing any fish from living in it
D Isostatic rebounding is allowing the lake to rise as the glaciers melt
Question #4
A Toxic gas killed off 60% of the park’s wildlife
B Yellowstone rose over 3 feet in elevation
C More than 500 earthquakes in 10 days
D Yellowstone erupted
Question #5
A It shows that the volcanic hot spot is shifting to the left
B It shows that pressure has been relieved in the volcano making an eruption unlikely to happen in the future
C It shows that the North American plate is moving
D It shows that the pressure has increased making an eruption likely in the next ten years
Question #6
A 50,000 years
B 1000 years
C A few million years
D 150,000 years
E 800,000 years
Question #7
A By subsidence caused by the piling up of heavy rock
B 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
C Yellowstone crater formed from a meteor impact that killed off the Ice Age mammals
D By basalt flows down cutting the slopes of the volcano
Question #8
A 2500 times
B 250 times
C 5 times
D 10 times
E 100 times
Question #9
A Volcanic ash from last Yellowstone super eruption, 640,000 years ago
B Large boulders blasted away from Yellowstone
C Ejected bones of bison from an earlier Yellowstone super eruption
D Basalts that flowed down to California from the Yellowstone volcano
Question #10
A Sandstone
B Basalt
C Rhyolite
D Granite
E Limestone
Question #11
A Erosion of old granite rock units
B Metamorphism of old beach deposits due to the high temperature of the hot springs
C Hot molten lava flow originating from deep below the earth crust, slow cooled and making its way towards the surface.
D Glacial deposits from the north
Question #12
A It is actually not faithful but erupts irregularly.
B 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.
C 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.
D River water slowly fills the reservoir under the crust and heats up with hot rock underneath.
Question #13
A It sinks a more than a foot per year causing groundwater to shoot to the surface
B It is home to the largest diversity of wildflowers
C Its large animals can only live at its 8,000 foot elevation
D Its strange geology
