6.1 Flashcard #1 Practice

Front

What is the Asthenosphere?

Back

The Asthenosphere is a semi-fluid layer of the Earth's mantle located below the lithosphere, which allows for the movement of tectonic plates.

Front

What is the Mantle?

Back

The Mantle is the layer of the Earth located between the crust and the core, composed of silicate rocks that are semi-solid and can flow slowly.

Front

What are Structural Layers of the Earth?

Back

Structural Layers of the Earth refer to the layers defined by their physical properties and behavior, including the Lithosphere, Asthenosphere, Mesosphere, Outer Core, and Inner Core.

Front

What is the Mesosphere?

Back

The Mesosphere is the layer of the Earth's mantle located below the Asthenosphere and above the Outer Core, characterized by increased pressure and temperature.

Front

What are Compositional Layers of the Earth?

Back

Compositional Layers of the Earth are layers defined by their chemical composition, including the Crust, Mantle, Outer Core, and Inner Core.

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 Inner Core?

Back

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

Front

What is the Outer Core?

Back

The Outer Core is the liquid layer of the Earth's core, located between the Inner Core and the Mantle, composed mainly of iron and nickel.

Front

What is the difference between Compositional and Structural Layers?

Back

Compositional Layers are defined by the materials they are made of, while Structural Layers are defined by their physical properties and behavior.

Front

What is the significance of the Asthenosphere in plate tectonics?

Back

The Asthenosphere allows for the movement of tectonic plates due to its semi-fluid nature, facilitating geological processes such as earthquakes and volcanic activity.
