The rock portion of Earth, made up of four different layers.

Soft, slow-moving layer beneath Earth's crust.

Earth's rigid outer layer, made up of the crust and solid, upper mantle that is broken into plates that move on top of the asthenosphere.

Layer beneath Earth's crust that is mostly less solid than the crust.

Liquid, metal layer surrounding Earth's inner core

The solid, metal center of Earth with high pressure and temperature

the thin, hard outer layer of Earth

Hotter areas of the fluid become less dense and rise, while cooler areas become denser and sink.

The denser ocean crust slides under the less dense ocean crust or the denser ocean crust slides under the less dense cont. crust

Term	Definition
Geosphere	The rock portion of Earth, made up of four different layers.
Asthenosphere	Soft, slow-moving layer beneath Earth's crust.
Lithosphere	Earth's rigid outer layer, made up of the crust and solid, upper mantle that is broken into plates that move on top of the asthenosphere.
Mantle	Layer beneath Earth's crust that is mostly less solid than the crust.
Outer Core	Liquid, metal layer surrounding Earth's inner core
Inner Core	The solid, metal center of Earth with high pressure and temperature
Crust	the thin, hard outer layer of Earth
convection currents	Hotter areas of the fluid become less dense and rise, while cooler areas become denser and sink.
subduction	The denser ocean crust slides under the less dense ocean crust or the denser ocean crust slides under the less dense cont. crust
