Earth Science Chapter 8 Plate Tectonics

The picture shows one example of evidence for continental drift. what evidence does it depict?

• similar fossils

• shape of coastlines

• land bridges

• rock types & structures

Spreading at divergent boundaries within a continent creates a

• trench

• rift valley

• subduction zone

• folded mountains

At what type of boundary is a subduction zone formed?

• transform

• convergent

• divergent

• strike-slip

Why does an oceanic plate subduct under a continental plate?

• because oceanic crust is thicker than continental crust

• because oceanic crust is heavier than continental crust

• because oceanic crust is younger than continental crust

• because oceanic crust is more dense than continental crust

The San Andreas fault formed due to a ___ boundary.

• transform

• convergent

• divergent

• subduction

An example of a hot spot is ___

• Appalachian Mountains

• San Andreas Fault

• Hawaii

• Mid-Ocean Ridge

Which is more dense?

• Continental Crust

• Oceanic Crust

What happens to temperature and pressure as you get to deeper layers within Earth?

• Temperature and Pressure increase

• Temperature increases, Pressure decreases

• Temperature decreases, Pressure increases

• Temperature and Pressure decreases

This image here shows what type of boundary?

• Divergent

• Convergent: Subduction

• Convergent: Collision

• Transform

The idea that the continents were once together, and separated over a long period of time is

• Seafloor Spreading

• Transform Boundaries

• Continental Drift

• Mid Ocean Ridges
