Plate Tectonics--IS3 (8th grade)

The movement of the tectonic plates is caused by

• the rotation of the Earth.

• convection currents in the Asthenosphere

• the gravity of the iron-nickel core.

• the Moho discontinuity.

The San Andreas Fault in California is known as an active earthquake area. What type of boundary is found at this fault?

• Converging

• Diverging

• Transform

• Sea Floor Spreading

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above

What is common feature at convergent boundaries?

• Valleys

• Canyons

• Mountains

• Rivers

The upper mantle is

• Innermost layer of solid metal.

• Solid material extending to Earth's core.

• Outermost layer of the Earth.

• Made up of the lithosphere and asthenosphere .

What does the theory of Continental Drift explain?

• Ocean currents move continents around the planet

• Convection works deep within the asthenosphere

• Mid-ocean ridges force tectonic plates to move

• Continents were once together and slowly drifted to where they are today
