Dynamic Earth

TermDefinition
Geosphere The rock portion of Earth, made up of different layers.
Athenosphere Soft, slow-moving laver, beneath Earths crust.
Lithosphere Earth's rigid outer/layer, made up of the crust and solid upper mantle that is broken into plates that move on to of the asthenosphere
Mantle Layer beneath Earths crust that is mostly less solid then the crust.
Outer core Liquid, metal layer surrounding Earths inner core
Inner core Solid ,metal, center of the Earth with high pressure and temp
Crust The thin hard outer layer of the Earth
Earth's layers from inner most layer to outer most layer. Inner core, Outer core, mantle, crust.
The farther you go into the Earth the pressure ____ Increases
Which layer is a solid metal ball made mostly of iron and nickel inner core
Mostly composed of liquid nickel and iron outer core
The movement of Earths plates is caused by convection currents found within which layer. mantle
Which layer is made of the three different types of rock, igneous, metamorphic and sedimentary. crust
Earth's layers from coldest to hottest crust,mantle, outer core, inner core.
Why Earths inner core is solid? high pressure.
The difference between outer core and inner core the outer core is fluid and the inner core is solid.
true or false, The mantle is solid but can flow under pressure true
true or false, the inner core is hallow false
lithosphere tectonic plates located in this sphere
continental crust thickest of the crust, least dense of the crust, granite
oceanic crust thinner then continental crust, more dense, basalt
convection currents solid, most dense happen in the asthenosphere
mantle 67% of Earths mass, magma.
mesosphere middle phere
who came up with continental drift theory (CDT) Alfred Wegener
continenta- contiental -collision -2 continental crust collide, buckles up pushing the crust up.
continental-oceanic: ocean crust crashes into cont. crust subduction: the denser crust (oceanic) slides under the dense crust (cont. crust)
oceanic-oceanic: Denser ocean plate slides under the less dense ocean plate subduction: Trench under the water
CDT The theory of all the contents being together. Evidence- rocks, fossils, glaciers, mountations, coast lines

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.
