Question	Answer
crust	earth's outer layer; the coolest and the least dense layer of earth. see also core, and mantle.
mantle	the layer of earth beneath the crust. it is about 2,900 thick, and makes up about 83 percent of earth's interior. see also core, and crust.
outer core	a layer of molten iron and nickel that surrounds the inner core of earth.
inner core	a dense sphere of solid iron and nickel at the center of earth.
latitude	the distance north or south of the equator measured in degrees. see also longitude.
longitude	the distance east or west of the prime meridian in Greenwich, England; measured in degrees. see also latitude.
oceanic ridge	a mountain-like landform that develops when tectonic plates move apart or separate and a new ocean lithosphere.
sea-floor spreading	a process by which new seafloor is formed from the magma rising from earth's diverging oceanic plates.
divergent boundary	location where two tectonic plates meet and are moving away from eachother.
transform boundary	location where two tectonic plates meet and slide past eachother. without creating a new landform.
subduction	the process by which one plate of the lithosphere sinks and slides under another.
ocean trench	long, deep formation on the ocean floor that develops where two tectonic plates are moving toward each other, and one is moving under the other.
tectonic plate	a piece of earth's crust that, according to plate tectonics, is pushed by movement in the asthenosphere
lithosphere	the cool, solid outer shell of earth. it consists of the crust and the rigid uppermost part of the mantle and is broken up into segments, or plates
