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