Volcanoes
When a volcano hits, this is the type of destruction where a cloud is full of rocks and gases.
What is pyroclastic flow?
What is the point deep in the Earth where the Earthquake happens?
What is the focus?
This type of FAULT is when the crust is pulling apart.
What is a normal fault?
What are P waves, S waves, then Surface Waves.
When the tsunami hit Japan in 2011, where did the waves hit that caused a lot of damage?
What is a nuclear powerplant.
Where do volcanoes form?
Along Plate Boundaries
Name two natural disasters that Earthquakes can cause.
1. Landslide
2. Tsunami
Which type of fault is present at an earthquake?
Strike Slip Fault
How do the seismic waves move?
Outward in all directions
How do Hot Spots help determine plate movement?
They can tell us where, and what direction islands are moving. It also tells us how fast they are moving.
This is the volcano where lava flows down the side gently.
Shield
This type of scale measures an Earthquakes energy.
Moment Magnitude Scale.
How is compression of rock different from shearing?
Compression squeezes rock together, while shearing pushes rock in opposite directions.
Why do I need THREE LOCATIONS to locate an Epicenter?
Narrow it down. If less then three it has too many locations.
How did mountains near the coast (like the Cascade Mountains form?)
As a result of an ocean plate subducting under a continental plate.
Which type of volcano has violent explosions!
What are three things that Earthquakes cause:
Landslides, earth shaking, tsunami
If you have a divergent boundary (one pulling a part) which fault would you find?
Normal Fault
The greater the distance between the P and S wave.....
Are you close or farther away?
Name THREE effects of Volcanic Ash
1. Break Roofs
2. Pollute Air
3. Roads slippery
4. Suffocation
5. Rich Soil
1. Name the three types of volcano descriptors (can they erupt or not)
2. Describe what each one means!!
1. Active / Dormant / Extinct
2. Active - can erupt anytime, Dormant - can not currently erupt but may anytime, Extinct - will probably never erupt again (dead).
Why do we not have to worry about Earthquakes in Ohio?
We are not near a plate boundary. Earthquakes do not happen here as common. If they happen, they are not strong.
If you have these plate boundaries:
Transform / Divergent / Convergent,
Tell which faults match the plate boundary:
Reverse / Normal / Strike Slip
Transform - Strike slip
Divergent - Normal
Convergent - Reverse
If an Earthquake took place in LA, where would the P and S waves travel first?
1. Cincinnati
2. Seattle
3. San Francisco
San Francisco
Where are Batholiths found?
Parallel to Subduction Zones
