Layers of the Earth Vocabulary

Asthenosphere

• The thin, solid, outermost layer of Earth; is either continental or oceanic.

• The solid layer of Earth between the crust and the core.

• The solid layer with plasticity in the upper mantle that is located just below the lithosphere.

• The sphere of solid nickel and iron at the center of Earth; surrounded by the liquid outer core

Crust

• The thin, solid, outermost layer of Earth; is either continental or oceanic.

• The solid layer of Earth between the crust and the core.

• The outer layer of Earth’s core; surrounds the inner core and is made of liquid nickel and iron

• The solid layer with plasticity in the upper mantle that is located just below the lithosphere.

Lithosphere

• The outer layer of Earth’s core; surrounds the inner core and is made of liquid nickel and iron

• The cool, rigid, outermost layer of Earth that consists of the crust and the uppermost part of the mantle; broken into pieces or segments called plates

• A characteristic of the material in the asthenosphere; existing in a solid state yet having the ability to flow

• The solid layer of Earth between the crust and the core.

Outer Core

• The outer layer of Earth’s core; surrounds the inner core and is made of liquid nickel and iron

• A characteristic of the material in the asthenosphere; existing in a solid state yet having the ability to flow

• The thin, solid, outermost layer of Earth; is either continental or oceanic.

Inner Core

• The cool, rigid, outermost layer of Earth that consists of the crust and the uppermost part of the mantle; broken into pieces or segments called plates

• The sphere of solid nickel and iron at the center of Earth; surrounded by the liquid outer core

Plasticity

• The sphere of solid nickel and iron at the center of Earth; surrounded by the liquid outer core.

• Force exerted on matter through contact with other matter; affects melting and boiling points.

• A characteristic of the material in the asthenosphere; existing in a solid state yet having the ability to flow.

• The solid layer of Earth between the crust and the core.
