8
What do scientists believe is the force behind the plate tectonics theory?
convection currents
gravity slab pull
the sun's gravity
rotation of Earth on its axis
9
Which of the following statements provides evidence for continental drift?
continents are moving at a rate of 2.5 centimeters per year.
same kind of fossils are found in South America and Africa.
same kind of rock layers are found in North America, Europe

10
Plate tectonics refers to the theory that
the crust was hot, then it cooled to form continents
all of the above
surface of the earth is made up of large plates that move
the continents float on the oceans

hot spots
rift valleys
mountain ranges
mid ocean ridges
16
What type of plate boundary is shown in the picture?
convergent
transform
subduction

17
The movement of the two continents may best be explained by
magnetic changes
coastal flooding
volcanic eruptions
plate tectonics
18
