TermDefinition
normal fault Usually occur when tectonic forces cause tension that pulls rocks apart.
Reverse Fault Occurs when tectonic forces causes compression that pushes rock together.
Strike-slip fault Forms when opposing forces cause rock to break and move horizontally.
folded mountain Forms when rock rock layers are squeezed together and pushed upward.
volcanic mountains located at convergent boundaries where oceanic crust sinks into the athenosphere at subduction zone
rift zone is a set of deep cracks that forms between two tectonic plates that are pulling away from each other
uplift The rising of regions of the Earth's crust to higher elevations
subsidence The sinking of regions of the Earth's crust to lower elevations
fault a break in a body of rock along which one block slides relative to another
folding the bending of rock layers due to stress
compression stress that occurs when forces act to squeeze an object
tension stress that occurs when forces act to stretch an object
transform boundary the boundary between tectonic plates that are sliding past each other horizontally
divergent boundary the boundary between two tectonic plates that are moving away from each other
convergent boundary the boundary formed by the collision of two lithospheric plates
tectonic plates a block of lithosphere that consists of the crust and the ridge, outermost part of the mantle
mesosphere the strong, lower part of the mantle between the asthenosphere and the outer core
lithosphere the solid, outer layer of the Earth that consists of the crust and the rigid upper part of the mantle
anthenosphere the soft layer of the mantle on which the tectonic plates move
core the central part of the Earth below the mantle
mantle the layer of rock between the Earth's crust and core
crust the thin and solid outermost layer of the Earth above the mantle
continental drift the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations
sea floor spread the process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies
plate tectonic the theory that explains how large pieces of the Earth's outermost layer, called tectonic plates, move and change shape

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
