(11 cards)
1
Q
Crust
A
Granite or besalt in composition
2
Q
Mantle
A
Peridotite in composition
3
Q
Core
A
Iron-nickel alloy
4
Q
Lithosphere
A
Crust and upper mantle (rigid)
5
Q
Astherosphere
A
Lower mantle (flows over time but solid)
6
Q
Outer core
A
Liquid iron-nickel alloy
7
Q
Inner core
A
Solid iron-nickel alloy
8
Q
Divergent plate boundaries
A
Away from each other, lithosphere made (MOR)
9
Q
Convergent plate boundaries
A
Towards each other, lithosphere being consumed (trench)
10
Q
Transform plate boundaries
A
Back and forth, lithosphere neither made or consumed (transform fault)
11
Q
Wadati-Benioff Zone
A
The band of earthquakes occurring in downgoing plates. (The mantle is solid and the downgoing plate is moving it.)
