Unit 3 Pre test

Front

What is the Asthenosphere?

Back

The asthenosphere is a semi-fluid layer of the Earth's mantle that allows tectonic plates to move.

Front

Where is the Lithosphere located?

Back

The lithosphere is located at the Earth's surface and extends down to about 100 kilometers into the mantle.

Front

What type of rock forms when lava cools and solidifies?

Back

Igneous rock.

Front

What is the primary cause of tectonic plate movement?

Back

Convection currents in the mantle.

Front

What are the five characteristics of a mineral?

Back

The five characteristics of a mineral are: naturally occurring, inorganic, solid, definite chemical composition, and crystalline structure.

Front

What is the difference between the Lithosphere and the Asthenosphere?

Back

The lithosphere is the rigid outer layer of the Earth, while the asthenosphere is a semi-fluid layer beneath it that allows for tectonic movement.

Front

What role do convection currents play in the Earth's mantle?

Back

Convection currents in the mantle drive the movement of tectonic plates.

Front

What is the definition of a mineral?

Back

A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure.

Front

How do igneous rocks form?

Back

Igneous rocks form when molten rock (magma or lava) cools and solidifies.

Front

What is the significance of the Earth's lithosphere?

Back

The lithosphere is significant because it is the layer where tectonic plates exist, influencing geological activity such as earthquakes and volcanic eruptions.
