Plate Tectonics CFA

Large pieces of lithosphere that move on top of the asthenosphere are called

• plate margins

• mantle pieces

• tectonic plates

• subduction zones

• tectonic movement

• sedimentation

• volcanic eruption

The heating and cooling of Earth's mantle causes

• convection currents which move the plates on the outer core.

• conduction currents which move the plates on the outer core

• convection currents which move the lithospheric plates.

• conduction currents which move the lithospheric plates.

What is happening at point W?

• Magma in the mantle is being heated by the hot core, causing it to rise toward the crust, then sink as it cools, the convection circuit pulling the tectonic plates

• Water in the mantle is being heated by the hot crust, which causes it to sink toward the core where it cools, the convection circuit pulling the tectonic plates.

• Energy from the Sun heats the crust, which conducts heat into the mantle, causing the magma to warm and sink toward the core, pulling the tectonic plates.

• Energy from the Sun heats the crust, causing it to shift and pull the tectonic plates, which uses friction to heat the magma in the mantle.

• Lithospheric plates join together under the ocean floor.

• Lithospheric plates are formed under the ocean floor.

• Lithospheric plates move apart under the ocean floor.

• Lithospheric plates rub together under the ocean floor.

What does the theory of continental drift state?

• All the continents were once one continent that broke up and drifted apart over hundreds of millions of years.

• The continents have always been separate but may one day drift together to form a single continent.

• The layout of the continents is the same today as it has always been.

• New continents are continually being created and destroyed.
