Coffin's High School -Earth's Compositional and Physical Layers

Front

What is the Asthenosphere?

Back

The Asthenosphere is a semi-fluid layer of the Earth's mantle located beneath the lithosphere, where tectonic plates float and move.

Front

What is the Lithosphere?

Back

The Lithosphere is the rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle.

Front

What is the Outer Core?

Back

The Outer Core is a liquid layer of the Earth composed mainly of iron and nickel, located beneath the mantle and surrounding the inner core.

Front

What is the Inner Core?

Back

The Inner Core is the solid, innermost layer of the Earth, composed primarily of iron and nickel, and is extremely hot.

Front

What happens to density as you move from the crust to the inner core?

Back

Density increases as you move from the crust to the inner core due to the increasing pressure and composition of materials.

Front

What is the Core of the Earth?

Back

The Core is the innermost compositional layer of the Earth, consisting of the solid inner core and the liquid outer core, and is the most dense layer.

Front

What is the Mantle?

Back

The Mantle is the thick layer of the Earth located between the crust and the core, composed of silicate rocks and is semi-solid.

Front

What is the Crust?

Back

The Crust is the outermost layer of the Earth, consisting of solid rock and is the least dense layer.

Front

What is the difference between the Lithosphere and the Asthenosphere?

Back

The Lithosphere is rigid and includes the crust and upper mantle, while the Asthenosphere is semi-fluid and allows tectonic plates to move.

Front

What is the role of tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact, causing geological events like earthquakes and volcanic eruptions.
