Which event best shows how tectonic plate movement can cause a series of geologic changes?

• A plate slides under another, causing earthquakes and volcanic eruptions.

• Two plates pull apart, causing changes in the weather

• Plates move together, speeding up the Earth's rotation

• A plate shifts sideways, changing ocean currents.

Which three features identify Earth's crust?

• It is the thinnest layer

• It is the most dense layer

• It is made of solid iron

• It is the least dense layer

• It is mostly rock

At a transform boundary, how do earthquakes form?

• Plates collide and fold upward, creating mountains

• Plates grind past each other until stress is released

• Plates move apart and magma rises to fill the gap

• Plates converge and form deep trenches

Which statement best describes the mantle?

• It is the thinnest, least dense layer

• It is the thickest layer, with magma that circulates

• It is a solid layer that creates Earth's magnetic field

• It is a lay of gas surrounding the crust

Which Earth layer is represented by the densest material in a classroom density model?

• Crust

• Mantle

• Outer Core

• Inner Core

What happens at a convergent boundary that causes volcanic arcs?

• The subducting plate melts as it sinks into the mantle

• Plates move apart and magma rises between them

• Plates separate, creating mid-ocean ridges

• The plates grind sideways, releasing heat.

Why isn't the Earth getting larger, even though new crust forms at divergent boundaries?

• Old crust is destroyed at subduction zones

• Earth's mass is lost into space

• Crust is constantly shrinking back into the mantle

• The mantle is becoming thinner

Which comparison correctly describes Earth's layers by thickness?

• The crust is thicker than the inner core

• The mantle is thicker than the outer core

• The outer core is thicker than the mantle

• The inner core is thicker than the mantle

Why is the mantle critical to plate movement?

• Convection currents in the mantle push and pull plates

• Earthquakes in the mantle constantly break the plates apart

• Magnetic forces in the mantle pull plates

• The mantle is made of solid rock that drags the crust
