Which of the following was NOT used by Wegener as evidence of continental drift?
Fossils that were found on different continents.
Magnetic reversals on the seafloor.
The fit of the continents.
Evidence of glacial scratches on continents found near the equator.
Which of the following is good evidence that South America and Africa were once joined together?
the shapes of their coastlines are very similar
they have similar distributions of rocks that are million years old
they both contain fossils of a type of plant species called Glossopteris
all of these
Which of the following processes contribute to the plate movement in the mantle?
convection in the mantle
the pulls of the moon
the earth’s rotation
the pull of the earth’s magnetic field
What discovery about the ocean floor is associated with the seafloor spreading?
Mountains are denser than the mantle
The magnetic poles of the Earth have
reversed
The crust of the continents is denser
than the crust of the ocean
The crust of the ocean is very young
relative to the age of the crust of the
continents.
Select a definition to what is an earthquake?
Earthquake is defined as when plates collide.
Earthquake is defined as when plates pull apart.
Earthquakes is the violent shaking off the ground.
Earthquakes is the sudden explosion of the crust.

Plate tectonics is our current theory of how the movement of continental masses relates to the movement of ocean basins. This movement explains many phenomena, such as
Earthquakes
Volcanoes
Tsunamis
All of the above
Plate tectonics, or the movement of pieces of Earth's crust, is thought to be caused by
Hot spots
Convection currents in Earth's crust
Convection currents in Earth's mantle
Convection currents in Earth's core
