12/11/2024 - **Practice: Unit 3 Plate Tectonics Summative Review

Front

What is the widest/biggest layer of the Earth?

Back

The Mantle is the widest/biggest layer of the Earth.

Front

What did critics of Wegener's theory think about his background?

Back

Critics thought he was not qualified to publish theories about geology.

Front

What part of the mantle is made up of soft solid (partially melted) rock?

Back

The Asthenosphere is the part of the mantle made up of soft solid (partially melted) rock.

Front

True or False: Plate motion is caused by earthquakes that push the plates around.

Back

False. Plate motion is caused by convection currents in the mantle.

Front

What keeps the inner core solid despite its high temperature?

Back

The inner core remains solid due to the immense pressure from the layers above.

Front

Define 'Plate Tectonics'.

Back

Plate Tectonics is the scientific theory that describes the large-scale movement of Earth's lithosphere, which is divided into tectonic plates.

Front

What are tectonic plates?

Back

Tectonic plates are large pieces of Earth's lithosphere that move and interact with each other.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper mantle.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the mantle beneath the lithosphere, allowing tectonic plates to move.

Front

What is the difference between the inner core and outer core?

Back

The inner core is solid due to high pressure, while the outer core is liquid.
