Earth Structures

TermDefinition
Mineral A natural, usually inorganic solid that has a characteristic chemical composition and an orderly internal structure.
element A substance that cannot be separated or broken down into simpler substances by chemical means all atoms of an element have the same atomic number.
atom The smallest unit of an element that maintains the properties of that element.
compound A substance made up of atoms or ions of two or more different elements joined by chemical bonds.
matter Anything that's has mass and takes up space.
crystal Natural solid substance that has a definite geometric shape.
streak The color of a mineral in powdered form.
luster The way in which a mineral reflects light.
cleavage In geology, the tendency of a mineral to split along specific planes of weakness to form smooth, flat surfaces.
weathering The natural process by which atmospheric and environmental agents, such as wind, rain, and temperature changes, disintegrate and decompose rocks.
erosion The process by which wind, water, ice, or gravity transports soil and sediment from one location to another.
deposition The process in which material is laid down.
igneous rock Rock that forms when magma cools and solidifies.
sedimentary rock A rock that forms from compressed or cemented layers of sediment.
metamorphic rock A rock that forms from other rocks as a result of intense heat, pressure, or chemical processes.
rock cycle The series of processes in which rock forms, changes from one type to another, is destroyed, and forms again by geologic processes.
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.
rift zone An area of deep cracks that forms between two tectonic plates that are pulling away from each other.
crust The thin and solid outermost layer of Earth above the mantle.
mantle The layer of rock between the Earth's crust and core.
convection The movement of matter due to the differences in density and the transfer of energy due to the movement of matter.
core The central part of Earth below the mantle.
lithosphere The solid, outer layer of earth that consists of the crust and the rigid upper part of the mantle.
asthenosphere The soft layer of the mantle on which the tectonic plates move.
mesosphere The strong, lower part of the mantle between the asthenosphere and the outer core.
Pangaea The super continent that formed 300 million years ago and that began to break up 200 million years ago.
sea floor spreading
plate tectonics The theory that explains how large pieces of the lithosphere, called plates, move and change shape.
tectonic plates A block of the lithosphere that consists of the crust and the rigid, outermost part of the mantle.
convergent boundary The boundary between tectonic plates that are colliding.
divergent boundary The boundary between two tectonic plates that are moving away from each other.
transform boundary The boundary between tectonic plates that are sliding past each other horizontally.
deformation The bending, tilting, and breaking of the Earth's crust the change in the shape of rock in response to stress.
folding The bending or rock layers due to stress.
fault A break in a body of rock along which one block moves relative to another.
shear stress
tension Stress that occurs when forces act to stretch an object.
compression Stress that occurs when forces act to squeeze an object.
earthquake
focus The location within earth along a fault at which the first motion of an earthquake occurs.
epicenter
tectonic plates boundary
elastic rebounds
volcano
magma
lava
vent
hot spot

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.
