Tricky Test Trivia
Subduction is when one plate goes under another plate. What causes this plate to go under the other plate?
Heat and pressure forms what type of rock?
Metamorphic Rock
What types of boundaries tend to form earthquakes?
All 3 boundaries.
Around what body of water is the Ring of Fire located?
Pacific Ocean
What plate boundary moves together?
Convergent Boundary
Why do earthquakes occur near the San Andreas fault?
Portions of the plates get stuck and then suddenly loosen and move.
How is sediment formed?
Weathering and Erosion
What is the cause of the earthquake activity on the West Coast of the United States?
The San Andreas Fault.
What type of boundaries do volcanoes form at?
Convergent and Divergent boundaries.
What plate boundary moves apart from each other?
Divergent Boundary
The San Andreas Fault is located in California. Annually, it is responsible for many earthquakes. Look at the image taken after the 1906 earthquake, which shows a fence that crosses the fault at a right angle. The fence was originally built in a straight line. What type of motion along the San Andreas Fault explains the change to the fence?
The plates move apart from one another.
How is a sedimentary rock formed?
It is compacted and cemented.
What type of wave is last to form in an earthquake?
Surface wave.
What is the liquid called when its inside of the volcano?
Magma
Which plate boundary moves past eachother?
Transform Boundary
Which provides the best evidence for the theory that faults and volcanoes are results of tectonic plate interactions?
Faults and volcanoes are often found at tectonic plate boundaries
How is an intrusive igneous rock formed?
Magma cools below the earths surface.
What is the second wave to be formed in an earthquake?
s waves
What is the liquid called when it is outside of a volcano?
Lava
What is it called when one plate sinks beneath another plate?
Subduction
Where is the highest risk of earthquakes in the U.S.?
California
How is an extrusive igneous rock formed?
When magma cools above the earth's surface
What type of wave is first to form in an earthquake?
p waves.
What are the 3 types of volcanoes?
cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes
Where do earthquakes and volcanoes mostly happen?
Plate boundaries
