Earth's outer layer; the coolest and least dense layer of Earth. See also Core and Mantle.

The layer of Earth beneath the crust. It is about 2,900 km (1,800 mi) thick, and makes up about 83 percent of Earth's interior. See also Core, and crust.

The distance north or south of the equator measured in degrees. See also longitude.

The distance east or west of the prime meridian in Greenwich, England; measured in degrees

A mountain-like landform that developed when tectonic plates move apart or separate and a new ocean lithosphere forms.

A process by which a new seafloor is formed from the magma rising from Earth's diverging oceanic plates.

location where two tectonic plates meet and are moving away from each other,

location where two tectonic plates meet and are moving toward each other.

location where two tectonic plates meet and slide past each other (without creation a new landform).

the process by which one plate of the lithosphere sinks and slides under another.

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.

a piece of Earth's crust that, according to plate tectonics, is pushed by movement in the asthenosphere.

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

the breakage of rock into two or more pieces.

Term	Definition
crust	Earth's outer layer; the coolest and least dense layer of Earth. See also Core and Mantle.
mantle	The layer of Earth beneath the crust. It is about 2,900 km (1,800 mi) thick, and makes up about 83 percent of Earth's interior. See also Core, and crust.
outer core
inner core
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
oceanic ridge	A mountain-like landform that developed when tectonic plates move apart or separate and a new ocean lithosphere forms.
sea-floor spreading	A process by which a 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 each other,
convergent boundary	location where two tectonic plates meet and are moving toward each other.
transform boundary	location where two tectonic plates meet and slide past each other (without creation 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
fracture	the breakage of rock into two or more pieces.
