Earth's Layers and Processes

Front

Lithosphere

Back

A rigid layer made up of the uppermost part of the mantle and the crust. Broken into plates.

Front

Asthenosphere

Back

The upper layer of the earth's mantle, below the lithosphere, in which convection is thought to occur.

Front

Inner core

Back

A dense sphere of solid iron and nickel at the center of Earth. Cannot melt due to enormous pressure.

Front

Basalt

Back

A dark, dense, igneous rock with a fine texture, found in oceanic crust.

Front

Subduct

Back

Movement of one part of Earth's crust under another.

Front

Outer core

Back

The liquid layer of the Earth's core that lies beneath the mantle and surrounds the inner core. Responsible for our magnetic field.

Front

What percent of the earth's surface is covered by water?

Back

71%.

Front

Convection

Back

Process by which, in a fluid being heated, the warmer part of the mass will rise and the cooler portions will sink.

Front

Iron and nickel

Back

Two elements making up the Earth's core.

Front

Geology

Back

The study of Earth's layers, convection in the mantle, plate tectonics, fossil fuels, and rocks and minerals.
