Unit 4- Plate Tectonics

What parts of the Earth make up the lithosphere?

Group of answer choices

• inner and outer core

• crust and upper mantle

• asthenosphere and mesosphere

• crust only

Which of these statements describes the asthenosphere?

• has convection currents

• hard or rigid

• broken into plates

• is at the center of the Earth

How do tectonic plates (lithospheric plates) move?

• wind currents from the air push on the plates

• convection currents in the outer core

• convection currents in the asthenosphere

• tectonic plates do not move
