asthenosphere
b)
transform boundary
c)
covergent boundary
d)
divergent boundary
2.
What is a long undersea mountain chain that has a steep, narrow valley at its center, that forms as magma rises from the asthenosphere, and that creates new oceanic lithosphere as tectonic plates move apart known as?
a)
sea-floor spreading
b)
mid-ocean ridge
c)
asthenosphere

terrane
3.
The process by which supercontinents form and break apart over millions of years is known as...
a)
continental drift
b)
supercontinent cycle
c)
plate tectonics
d)
rifting
4.
The study of the alignment of magnetic minerals in rock, specifically as it relates to the reversal of Earth's magnetic poles is known as what?
a)
panthalassa
b)
pangaea
c)
paleomagnetism

plate tectonics
5.

a)
pangaea
b)
panthalassa
c)
terrane

asthenosphere
6.
The solid, outer layer of Earth that consists of the crust and the rigid upper part of the mantle is called the...
a)
convergent boundary
b)
asthenosphere

11.
What is the process by which new oceanic lithosphere forms when magma rises to Earth's surface at mid-ocean ridges and solidifies, as older, existing sea floor moves away from the ridge called?

rifting
b)
panthalassa
c)
sea-floor spreading
d)
paleomagnetism
12.
