Which type of plate boundary would cause mountains to form?
Convergent
This layer of Earth is solid Iron and Nickel
Inner Core
The Great Rift Valley in Africa and the Mid-Ocean Ridge were all created by this boundary
Divergent
This layer of Earth is the thickest part
mantle
What are the two types of crust
continental and oceanic
Which layer has convection currents?
Mantle
subduction zones in the ocean can create which features?
islands volcanos earthquakes
Earthquakes and volcanoes are most likely found in which locations?
At plate boundaries
melts, rises
The Himalayas in Asia are an example of what type of plate boundary?
continent-to-continent convergent
Transform boundaries are most likely to produce what phenomenon?
earthquakes
When an oceanic plate and a continental plate collide, which one will subduct?
oceanic
Which of the following is NOT a tectonic boundary
Sedergent
when did pangaea begin
about 300-200 million years ago
new oceanic lithosphere forms where??
midocean ridges
what motion is a transform boundary
sliding motion
what boundary causes earthquakes
convergent boundaries.
subduction zones
what boundary makes rift valleys
divergent boundary
the outer core is.....dense the mantle
nearly twice as dense as the mantle (more dense)
what motion is a convergent boundary
colliding motion
what boundary is the san andreas fault
what increases with distance from a mid ocean ridge
The age, density, and thickness of oceanic crust
how does the ocean crust form
constantly formed at mid-ocean ridges, where tectonic plates are tearing apart from each other.
who came up with the plate theory
Alfred Wegener
