Plate Tectonics Final

At which point will the oldest rock be found? Explain.

• Older rock will be found at Y since it is closer to the ridge.

• Older rock will be found at X since it is deeper there than at the ridge.

• Older rock will be found at Y since it is hotter there than farther away.

• Older rock will be found at X since sea-floor is pushed away from the ridge when new crust is formed.

Most geologists rejected Wegener's idea of continental drift because...

• they were afraid of new ideas

• Wegener was interested in what Earth was like millions of years ago, but not today

• Wegener used several different types of evidence to support his hypothesis

• Wegener could not identify a force that could move the continents

What is the correct order (starting from the surface) of Earth's layers?

• crust, outer core, inner core, mantle

• mantle, outer core, inner core, crust

• crust, mantle, outer core, inner core

• crust, outer core, mantle, inner core

The geological theory of _______ states that pieces of Earth’s lithosphere are in constant, slow motion

• subduction

• plate tectonics

• deep ocean trenches

• sea-floor spreading
