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

What are lithospheric plates?

• Tectonic plates that do NOT move

• parts of continental crust only

• parts of the ocean crust only

• lithosphere that is broken into "plates" that move

Which of these statements best describes the Lithosphere?

• hard or rigid

• has convection currents

• is the densest layer

• is at the center of the Earth

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

When two plates move apart, what type of boundary forms?

• neutral

• convergent

• divergent

• transform

What feature can form from a continental plate converging with another continental plate?

• a trench

• non-volcanic mountain range

• volcanoes

• mid-ocean ridge

Volcanoes are not common at transform boundaries. Why?

• no magma is formed because there is no subduction or rift

• transform boundaries collide

• transform boundaries pull apart

• Mountains only crumple up
