As the rocks become cooler, they become denser and move down the slope of the asthenosphere. What force moves them down the slope?
gravity
100
What happens at a divergent tectonic plate boundary?
Two tectonic plates pull away from each other.

What is the difference in Earth's inner core and Earth's outer core? [two differences for two clicks]
The inner core is solid and hotter and more dense.

Which tectonic boundary does not produce lava or any new formation?
a transform boundary
200
What is subduction?
A.when magma deep in Earth's mantle rises to the surface
B. the downward movement of a plate of the earth's crust into the mantle beneath another plate.
C. when underwater volcanoes form from convergent boundaries
D. when marine life flourishes near hot water vents
B. the downward movement of a plate of the earth's crust into the mantle beneath another plate.

B. oceanic-continental convergent
C. oceanic-oceanic convergent
D. oceanic-oceanic divergent
B. oceanic-continental convergent
pyroplastic volcano

As the rocks become cooler, they become denser and move down the slope of the asthenosphere due to gravity.
What is this mechanism called?
slab pull
300
What type of boundry occurs between the Juan de Fuca and the North American plate at the San Andres fault?
transform boundry
300

A. rift valley B. mid ocean ridge
C. deep ocean trench D. folded mountains
E. volcanoes
A. rift valley
400
Where does our data about layers of the Earth come from?
seismic data
400
What are these Pacific Rim pyro-volcanoes called?
400
What is this?
Great African Rift Valley

Tectonic plates are made of continental crust, oceanic crust or a combnation of the two. Besides their locations, how else are these two kinds of crust different? [Double click for two answers]
Continental plates are thicker and less dense; conversely, oceanic plates are thinner and denser.
400
What formations occur when an oceanic plate collides with a oceanic plate?
[There may be more than one answer.]
A. rift valley B. mid ocean ridge
C. deep ocean trench D. folded mountains
E. volcanoes
C. deep ocean trench
E. volcanoes
