Continental Drift

the theory that the continents had once been one big continent that broke up and moved around to their present-day positions

how much space an object takes up (its volume) in relation to the amount of matter in that object (its mass). Another way to put it is that density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density.

• magma

• divergent boundary

• density

• convection

a break in the earth’s crust either within a plate or between plates

• fault

• convection current

• hotspot

• divergent boundary

NGSS.MS-LS4-2

the hard outer layer of Earth made of crust and hard, upper mantle; broken into tectonic plates

• asthenosphere

• outer core

• lithosphere

• inner core

molten rock under the surface of Earth

• lava

• magma

• fault

• convection

sections of the lithosphere that move on top of the fluid asthenosphere; composed of Earth’s crust and the hard top layer of the mantle

• tectonic plate

• convection current

• fossil

• magma

the edge of a tectonic plate where earthquakes, volcanoes, and other tectonic activity takes place because of the motions of the plates

• fossils

• plate boundaries

• convection currents

• faults

NGSS.MS-ESS3-2

a volcanic area that forms as a tectonic plate moves over a place heated from deep within Earth; the Hawaiian islands are an example

• convection current

• fault zone

• hotspot

• geyser
