Plate Tectonics/Boundaries

Front

What is a tectonic plate?

Back

Large slabs of rock that move on the liquid mantle (asthenosphere)

Front

What is Pangaea?

Back

All continents joined in one large land mass

Front

What is convection?

Back

Heat transfer by the movement of material.

Front

What is a convection current?

Back

Movement from the soft rock's heat rising. Then falling once it cools.

Front

Which layer holds the tectonic plates? Options: Asthenosphere, Atmosphere, Lithosphere, Mesosphere

Back

Lithosphere

Front

Which layer has convection currents which move the tectonic plates? Options: Asthenosphere, Atmosphere, Lithosphere, Mesosphere

Back

Asthenosphere

Front

What is the theory of plate tectonics?

Back

The plates on Earth's lithosphere are in constant slow motion because of convection currents in the atmosphere.

Front

What is the theory of continental drift?

Back

All continents were joined in a single land mass. Over time they drifted apart.

Front

Which scientist developed the theory of continental drift?

Back

Alfred Wegener

Front

True or False: There is little evidence to support the theory of continental drift.

Back

False
