Casteel Erosion etc.

Casteel changing Earth

TermDefinition
The crust is composed primarily of rocky material.
The mantle is composed mostly of solid rock with some molten rock.
The innermost layers are composed mostly of iron and nickel.
Pressure and temperature increase with depth beneath the surface.
Large continent-size blocks are called plates
Most earthquakes and volcanoes are located at the boundaries of the plates (faults).
when plates move together convergent boundaries
when plates move apart divergent boundaries
when plates slip past each other horizontally transform boundaries, also called strike-slip or sliding boundaries
moving sediments to a new location erosion
dropping sediments in a new location deposition
Ring of Fire The area of tectonic plates with the most amount of active volcanoes in the world.
Lava This is magma outside of the Earth.
Pangaea This is the theory of a "super continent", when the Earth was a single landmass.
mantle The thickest layer of the Earth.
Earthquakes Caused by shifting of tectonic plates usually at a transform boundary
Transform Faults plates slide or slip past each other; cause earthquakes
volcanoes Magma from the mantle comes out of these
Trenches When convergent plates come together and push downward, these form.
Mountains When convergent plates come together and push upward, these form.
Mid-ocean ridges When divergent plates come apart, and magma seeps up, forming new crust.
faults These are the boundary lines between tectonic plates.
Divergent Faults plates move away from each other; Mid-ocean ridges and rift valleys are formed by these
Convergent Faults plates move towards each other; cause mountains, volcanic arcs, and deep ocean trenches

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.
