Which list of layers are the compositional layers?

• Crust, Mantle, Outer Core, Inner Core

• Lithosphere, Asthenosphere, Core

• Crust, Mantle, Core

• Lithosphere, Mantle, Outer Core, Inner Core

Which of the following causes magma inside the Earth to rise toward the surface.

• The magma is becoming cooler and less dense

• The magma is becoming cooler and denser

• The magma is becoming warmer and denser

• The magma is becoming warmer and less dense

The convection currents that drive the plate motion are found primarily in which layer of the Earth?

• Asthenosphere

• Crust

• Inner Core

• Lithosphere

Why wasn't Wegener's Continental Drift hypothesis accepted.

• continental landmasses were too big to move slowly over Earth’s surface

• magnetic and sonar data proved that Wegener’s hypothesis was incorrect

• mantle convection currents weren’t in motion at that time

• Wegener couldn’t explain why or how the continents moved

Which of the following best describes the value of studying geology?

• Geology isn’t as important as the other types of science, like astronomy.

• Rocks have stories to tell. By learning more about the rocks, we can learn more about Earth’s history.

• There is no value because rocks change so frequently that we can’t really understand them.

• Understanding rocks will really impress your friends.

As rock moves away from the mid ocean ridge it gets __________ than the rock being produced at the ridge.

• Older

• Younger

• Magnetic

Which theory combined the theories of Wegener, Hess, and others.

• Continental Drift

• Sea Floor Spreading

• Ridge Push and Slab Pull

• Plate Tectonics

Which explanation is correct about hot spots.

• Hot spots move under a stationary lithospheric plate

• Hot spots remain stationary

• Hot spots do not move but melt through a non moving lithospheric plate

• Hot spots do not move but repeatedly melt through a moving lithospheric plate.

Why are so many Earthquakes and Volcanoes found at convergent plate boundaries.

• Because energy is escaping from inside the earth through the middle of the tectonic plates.

• Because energy is escaping from inside the earth around the edges of the tectonic plates.

• The earth is absorbing energy at those locations.

• Because scientists knew that that is where the tectonic plates are so they just wanted to outline each of the plates.

Which plate is plate E?

• South American Plate

• Pacific Plate

• North American Plate

• Juan De Fuca Plate
