Layers
What are the three Compositional Layers?
Crust, Mantle, Core
What are the three types of boundaries?
This is the name of the theory that we use today.
Plate Tectonics
What is the type of heat transfer responsible for seafloor spreading?
Convection
What is the name of the guy who came up with the theory of Continental Drift?
Alfred Wegener
What are the five physical layers?
Lithosphere, Asthenosphere, Mesosphere, Outer Core, Inner Core
This boundary forms mountains.
Convergent Continental - Continental
This is the name of the original theory that plate tectonics is built upon.
At what boundary does new crust form?
Divergent
What is the name of the guy who discovered seafloor spreading?
Harry Hess
Which layer is the only layer made of liquid?
Outer Core
The boundary creates volcanoes.
Convergent Oceanic - Continental
This evidence proves plate tectonics and is found at divergent boundaries.
Seafloor Spreading
Convergent Oceanic - Continental
What is another name for Convergent Oceanic - Continental boundaries?
Why is the inner core a solid?
It is under so much pressure that it stays a solid
Mid Ocean ridges and rift valleys are formed at this type of boundary
Divergent
The continents fitting together like a puzzle is primarily evidence for what theory
Continental Drift
Which physical layer of the Earth is responsible for the changes in the Earth's surface?
Asthenosphere
What do we call the volcanoes around the Pacific Plate?
The Ring of Fire
List the physical layers in order of most to least solidity.
Inner Core, Mesosphere, Lithosphere, Asthenosphere, Outer Core
This boundary is responsible for forming the deepest parts of the ocean.
Convergent Oceanic - Oceanic
Paleomagnetism
How does the recycling of the Earth's crust affect our study of the Earth's history?
What is another way for crust to be formed in the middle of a plate, away from a boundary?
Hot Spots
