The theory of continental drift states that all the continents were once part of one big landmass called Pangaea. Who was the scientist that came up with this theory?
Harry Hess
Bill Nye
Alfred Wegener
Albert Einstein
Which of the following evidence was used to support theory of continental drift?
A) Continents fit together like a puzzle
B) Similar fossils were found on separate continents
C) Different types of rock, mountain structures, landforms are found all over the world.
D) All of the above
E) Only A and B
Why was Alfred Wegener unable to explain his theory?
He couldn't explain how the continents drifted.
He couldn't explain why similar fossils on different continents were separated
He couldn't explain why similar geological structures found were found on different continents.
He couldn't explain why the continents fit together like a puzzle.
If you took rock samples from the Mid-Atlantic Ridge, the youngest rock would be
located where the plates collide
located at the place where rocks are furthest from the rift valley
Located at the center of the ridge (rift valley), where oceanic crust is formed
none of the above; all the rocks would be the same age
Seafloor Spreading occurs at a
convergent boundary
divergent boundary
transform boundary
continental boundary
Tectonic plates float on top of the
crust
asthenosphere
lower mantle
outer core
The San Andres Fault is an example of a
convergent boundary
divergent boundary
transform boundary
subduction zone
What type of plate boundary is shown in this picture
a convergent oceanic-oceanic boundary
a divergent oceanic-oceanic boundary
a convergent oceanic-continental boundary
a divergent oceanic-continental boundary
This picture shows
a transform boundary where one continental crust is sliding past another continental crust
a convergent boundary where one continental crust is moving towards another continental crust and mountains are forming
a divergent boundary, where one oceanic crust is moving away from another oceanic crust
a convergent boundary where one oceanic crust is moving toward a continental crust
At which type of boundary do you find most earthquakes form
divergent boundary between two oceanic plates
transform boundary between two oceanic plates
convergent boundary at a subduction zone
transform boundary between two continental plates sliding past each other
