Land Beneath Our Feet: Study Tool

Which of the following is NOT a result of a divergent boundary?

• Subduction zones

• Mid Ocean ridges

• new ocean crust

• seafloor spreading

Which best describes what makes the tectonic plates?

• slabs of the mantle

• oceanic crust and continental crust

• slabs of the lithosphere and asthenosphere

• Magma and lava

Which best describes the cause for the movement of tectonic plates?

• Gravitational pull between Earth and the moon.

• Convection currents beneath the Earth’s crust.

• Energy produced by earthquake within the Earth.

• Energy produced by earthquake within the Earth.

What evidence did Alfred Wegener use to support his theory of Continental Drift?

• Rocks and fossils found to be similar on different continents

• Convection currents in the asthenosphere and sea-floor spreading

• Sea-floor spreading

• Fossils from ancient organisms and convection currents sin the asthenosphere

Which geologic events is most likely to occur at a transform boundary?

• Rift formation

• Volcanic eruption

• earthquake

• Mountain formation

Which statement best describes the outcome of the collision between oceanic and continental crust?

• Both portions will stop moving

• The continental crust will subduct under the oceanic crust

• The two portions will slide past each other

• The oceanic crust will subduct beneath the continental crust

Which part of the earth is broken into several large tectonic plates?

• Lithosphere

• Mantle

• Asthenosphere

• Outer Core

Which movement of the tectonic plates would most likely result in large mountain formations?

• Two oceanic plates colliding

• Two oceanic plates spreading apart

• Two continental plates colliding

• Two continental plates spreading apart

Why does Earth have 4 layers?

• Because all have the same temperature.

• Because all have the same density

• Because each layer has a different density

• Because each layer gets cooler as you get to the center of the Earth

What makes scientists think that the outer core is liquid?

• S- waves make it all the way through the planet to the other side.

• S-waves go through liquids while P-waves don’t

• P-waves go through liquids while S-waves don’t go through them.

• P-waves are much faster than S-waves.
