plate movement

TermDefinition
crust he hard, outermost layer or surface covering of an object
mantle something that blankets over something else
outer core a liquid layer, approximately 2,200 km (1,367 miles) thick, composed mainly of iron and nickel, located between Earth's mantle and inner core
inner core a 2,200 km thick liquid layer of iron and nickel responsible for the magnetic field.
latitude the measurement of distance in degrees north or south of the Equator,
longitude Longitude is the measurement of east-west position on Earth,
oceanic ridge a continuous, seismic, underwater mountain system, typically 2,500m deep, formed
sea floor a geological process where tectonic plates pull apart at mid-ocean ridges, allowing magma to rise from the mantle, harden, and create new oceanic crust.
divergent boundary a linear, constructive feature where two tectonic plates move apart from each other.
transform boundary a geological process where one of Earth's tectonic plates sinks beneath another into the mantle at a convergent
subduction the geological process where one tectonic plate is forced beneath another into the Earth's mantle
ocean trench a long, narrow, V-shaped depression in the ocean floor that represents the deepest parts of the ocean
tectonic plate massive, rigid slabs of solid rock composing Earth’s outer shell, known as the lithosphere.
lithosphere the solid, rigid outer shell of the Earth, consisting of the crust and the topmost part of the upper mantle.
fracture a number expressed as a ratio of two integers—a numerator over a denominator—rather than a decimal.
elasticity the ability of a material, body, or economic variable to return to its original shape, size, or state after being deformed, stretched, or influenced by a change in conditions.
stress the body’s natural, automatic reaction to challenges, demands, or threats.
strain injury to a muscle (often caused by overuse); results in swelling and pain.
plate boundary the edges where Earth's tectonic plates meet
continental the thin, dense, and young outer layer of Earth’s lithosphere that forms the floor of the ocean basins.
ocean crust the thin, dense, and young outermost layer of Earth’s lithosphere, typically 5–10 km thick, that underlies the
friction a force that slows things down or stops them from moving when two surfaces rub together.
rift valley a linear, steep-sided lowland formed where Earth's tectonic plates diverge (pull apart), causing the crust to sink
oceanic ridge A continuous, under mountain system formed at mid-ocean ridges causing tectonic plates to slowly move apart.

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.
