Plate Tectonic Theory
100
The place on the Earths surface where waves originate from.
What is the Epicenter
100
The type of Volcano with a broad base and gently sloping sides.
What is a Shield Volcano
100
The plates are pieces of the Earth structure that slide around one another.
What is the Crust
100
The mechanism that drives the Earth's tectonic plates to move.
What is Convection
100
This man came up with the idea of Continental Drift.
What is Alfred Wegener
200
These waves move out from the Epicenter.
What is Surface Waves
200
What is the main difference between Lava and Magma
Magma= In the Earth Lava= Out of the Earth
200
The Himalayan mountain range is an example of this type of Plate Boundary
What is Convergent
200
The two main differences between the layers of the Earth.
What is Pressure and Density
200
This is what Pangaea means
What is All Land
300
The system we use to assign strength of a wave.
What is Richter Scale
300
What causes the Magma to rise up through the Continental plate to form a Volcano
It is less dense
300
When an Ocean plate slides underneath a Continental plate it is called this
Subduction
300
This is the word used to describe the "thickness" of a material. Peanut Butter vs. Water
What is Viscosity
300
One of the three(3) pieces of evidence supporting Continental Drift
1.) Rock Layering 2.) Puzzle piece continents 3.) Fossil Records
400
The place where Body waves originate from.
What is the Focus.
400
The name of the last major volcanic to erupt in the United States. (Washington State)
What is Mt. St. Helens
400
The only Transform plate boundary in North America is in this state
What is California
400
When crust formed on the Earth.
What is 3.7-4 billion years ago
400
This man supported the idea of Continental Drift by proving Sea Floor Spreading.
What is Henry Hess
500
These waves travel parallel to the direction the wave is traveling and are compressional waves.
What is Primary waves
500
Why the Hawaiian Islands are volcanoes
They are growing over Hot Spots
500
Divergent Plate boundaries cause cause these two Earth features.
Mid-Ocean Ridges and Rift Valleys
500
This is what we study to learn all we know about the Earths Interior
