Inner Earth

crust It is the thinnest layer, made up of rocks, dry land and ocean floor. Oceanic and continental crusts are found here.
continental crust Rock made up of granite. Found in the crust, and is MORE dense than oceanic crust.
oceanic crust Rock made up of basalt. Also found in the crust, and is LESS dense than continental crust.
mantle It is the thickest layer and is made up hot, dense rock.
inner core Part of the core, and it is made up of SOLID iron and nickel (metal).
outer core Part of the core, and it is made up of LIQUID iron and nickel (metal). Most dense of all of Earth's layers.
lithosphere Consists of hard rock and it is attached to the crust. Divided into sections called tectonic plates, in which floats independent of each other (100 kilometers thick).
asthenosphere A layer of SOFT rock that moves slowly over time, because of convection currents. They cause the plates to move, and the lithosphere floats on top of this layer.
conduction Transferred heat by direct contact, just like if someone is on fire. ;)-
convection Transferred heat by movement of liquids and gases due to density differences.
radiation Transferred heat by no contact at all, like heat from a fire.
convection currents Convection currents are the movement of magma in the asthenosphere. The core heats up magma, it becomes less dense and rises. Then it cools, because more dense sinks. The up and down effect of this moves the plates.
plate tectonics The lithosphere that are broken into separated pieces.
Pangaea It was a land that had all of the continents together, about when dinosaurs was in existence.
continental drift It was the theory of Alferd Wegener made that all the continents were once together, but then separated in the continents they are today.
sea-floor spreading the process by which new oceanic lithosphere forms as the magma rises toward the surface and solidifies.
subduction It is the process of when the denser crust will sink into the asthenosphere at the deep trench and repeats.
deep ocean trench Where the oceanic crust is bent downward, because of subduction.
Mid-ocean ridge The longest mountain chain in the world and it is on a divergent boundary. (active volcano)
sonar It is the type of tool we use to map the ocean floor.
convergent It is a boundary that pushes the continents together. They can form mountains(continental vs oceanic), trenches and volcanoes (continental vs oceanic and oceanic vs oceanic).
divergent It is a boundary that separates the continents. With continental plates, it can form a rift valley, and with oceanic plates it forms the mid-ocean ridge.
transform They are a type of boundary can make earthquakes by SLIDING past each other.
continental vs continental They can form mountains
continental vs oceanic they can form trenches and volcanos
oceanic vs oceanic Forms trenches and volcanos
