The continents were once joined in a super-continent and have moved over time
The earth is broken into lithospheric plates that moved at one time and are now stationary
Continents have always been stationary and do not move
None of the above
The Appalachian Mountains in the U.S. match up with a similar mountain range in Northern Europe. How does this support Wegener’s theory of continental drift?
The mountains were formed after tectonic plates had moved away from each other
The similarities provide evidence North America and Europe were connected when the mountains formed
Similar rock samples were found on the ocean floor and at the two mountain ranges indicating that they both formed around the same time.
This evidence does not support the theory of continental drift
What layer of earth is responsible for the movement of the tectonic plates?
Inner Core
Outer Core
Asthenosphere
Atmosphere
The mid-ocean ridge is an underwater plate boundary where new land is being created from cooling mantle. What type of plate boundary is found here?
Convergent
Divergent
Transform
Subduction
The mid-atlantic ridge is an example of a divergent boundary where new land is being created from magma rising from the mantle. During the process of seafloor spreading, where can the youngest land be found?
