What occurred to cause the 2011 earthquake in Japan?
two plates were colliding, one was subducting under the other building up energy released by the earthquake
two plates were pulling apart, magma was forming new rock and building up energy released by the earthquake
two plates were colliding, creating a volcanic eruption and building up energy released by the earthquake

What occurred to cause the tsunami in the Indian Ocean in 2004?
two plates were colliding
a fault ruptured
a large wave was created by the movement on the ocean floor

If you see bent trees on a hill, what most likely took place in that location?
creep occurred as soil slowly moved down hill
the tree roots broke down the rocks into soil
a landslide suddenly occurred
an earthquake caused the trees to bend
If you see large cracks in rocks and freezing and thawing is a regular occurrence, what most likely took place in that location?
the freezing and thawing of water caused small cracks to become larger over time
tree roots create the large cracks in the rocks
lightning struck creating large cracks in the rocks
an earthquake caused the large cracks in the rocks
If you find a large piece of granite on the surface of the earth, what can you conclude?
the granite formed from a volcano that erupted in that location
weathering and erosion exposed the granite over time
the granite formed from heat and pressure
sediments piled up over time and formed the granite
If you find gneiss in a location, what can you conclude?
subduction may have occurred nearby
sediments were deposited and compacted together
granite was most likely exposed to heat and pressure
rivers and streams may be nearby
If you find basalt in a location, what can you conclude?
a volcano may be nearby
sediments were deposited and compacted together
granite was most likely exposed to heat and pressure
lava cooled quickly on the surface
magma cooled slowly underground
If you find slate in a location, what can you conclude?
a volcano may be nearby
sediments may have been deposited and compacted together
shale may have been exposed to heat and pressure
rivers and streams may be nearby
If you find shale in a location, what can you conclude?
a volcano may be nearby
gravel and sand may have been deposited and compacted together
mud and clay may have been deposited and compacted together
rivers and streams may be nearby
slate may have been exposed to heat and pressure
