Round and Round
The amount of molecules packed into a space or volume
Density
When two tectonic plates collide.
Convergent
Convergent C-C
The Cascadian Subduction Zone is made by this plate boundary type.
Convergent C-O
A large chunk of Earth's crust (and a little bit of the lithosphere).
Tectonic Plate
Cold fluids will... (3 answers)
1. Sink
2. More dense
3. Clump together
When two tectonic plates divide
Divergent
This plate boundary type creates Fault Zones.
Transform
A shield volcano will be ______________ & have ________________ compared to a composite volcano being cone shaped and having explosive eruptions.
dome shaped & "oozy eruptions"
These tectonic plates are more dense.
oceanic plates
Hot fluids will... (3 answers)
1. Rise
2. Less Dense
3. Spread out
When two tectonic plates slide
Transform
This plate boundary type creates Volcanic Mountain Ranges
Convergent C-O
This Cascade volcano has the potential to be the most deadly due to it's glaciers ability to form dangerous lahars.
Mt. Ranier
Once piece of evidence that supports the theory of plate tectonics is...
Fossil Evidence
Climate Evidence
Glacial Striations
Mountain Chains
Rock Strata
The movement of a fluid in a circular motion du tot changes in temperature and density.
Convection Current
This is when one plate sinks below another plate.
Subduction Zone
This plate boundary type creates volcanic islands and deep ocean trenches.
Convergent O-O
An earthquake is the shaking of the ground due to this, made by the plates moving suddenly.
Seismic Waves
This is what fossil evidence proves.
Organisms that couldn't swim lived on continents separated by an ocean proving they were once connected.
Describe steps A-E of a convection current.
B. The hot, less dense magma molecules spread out and rise.
C. The magma is far away from the energy source so it cools.
D. The cool, more dense magma molecules pack together making it sink.
E. The magma is reheated and repeats the convection current.
The difference between a divergent boundary making a rift valley and a mid ocean ridge.
Time! The age of the boundary.
These are the 3 geologic features made by Divergent Boundaries.
1. Mid Ocean Ridges
2. Rift Valleys
3. New Sea Floor
This is why tsunamis and regular waves are not the same thing.
Tsunamis move through the whole water column while waves only affect the top of the water column.
This is what Spitsbergen or tropical plant fossil evidence proves.
That tropical plants found on an iced over island had to lived in a warmer climate which means the island had to be closer to the equator.
