Plate Tectonics/Boundaries

1. What is a tectonic plate?

• Heat transfer by the movement of material
• Movement from the soft rock's heat rising. Then falling once it cools.
• Large slabs of rock that move on the liquid mantle (asthenosphere)
• All continents joined in one large land mass

2. What is Pangaea?

• Heat transfer by the movement of material
• Movement from the soft rock's heat rising. Then falling once it cools.
• Large slabs of rock that move on the liquid mantle (asthenosphere)
• All continents joined in one large land mass

3. What is convection?

• Heat transfer by the movement of material
• Movement from the soft rock's heat rising. Then falling once it cools.
• Large slabs of rock that move on the liquid mantle (asthenosphere)
• All continents joined in one large land mass

4. What is a convection current?

• Heat transfer by the movement of material
• Movement from the soft rock's heat rising. Then falling once it cools.
• Large slabs of rock that move on the liquid mantle (asthenosphere)
• All continents joined in one large land mass

5. Which layer holds the tectonic plates?

• Asthenosphere
• Atmosphere
• Lithosphere
• Mesosphere

6. Which layer has convection currents which move the tectonic plates?

• Asthenosphere
• Atmosphere
• Lithosphere
• Mesosphere

7. What is the theory of plate tectonics?

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

• The soft, hot rock in the asthenosphere rise, then cool and sink again. This happens over a long period of time, but causes slight movements of a few centimeters per year.
• All continents were joined in a single land mass. Over time they drifted apart.

8. What is the theory of continental drift?

• The plates on Earth's lithosphere are in constant slow motion because of convection currents in the atmosphere.
• The soft, hot rock in the asthenosphere rise, then cool and sink again. This happens over a long period of time, but causes slight movements of a few centimeters per year.
• All continents were joined in a single land mass. Over time they drifted apart.

9. Which scientist developed the theory of continental drift?

• Isaac Newton
• Charles Darwin
• Albert Einstein
• Alfred Wegener

1. Which layer of Earth creates movement for plate boundaries to occur?

• Asthenosphere
• Atmosphere
• Lithosphere
• Mesosphere
