Plate Tectonics Review

What drives tectonic plate movement? 

• gravity
• coriolis effect
• convection currents
• the earth's magnetic core

Two tectonic plates collide at a ___ plate boundary.

• convergent
• divergent
• transform
• transformer

Two tectonic plates collide at a ___ plate boundary.

• convergent
• divergent
• transform
• transformer

This land form can occur at a divergent plate boundary.

• trench
• mid-ocean ridge
• folded mountains
• fault

According to Wegener's hypothesis of continental drift, 

• Earth's surface is made up of seven major landmasses
• the continents DO NOT move
• Earth is slowly cooling and shrinking
• the continents were once joined together in a single landmass

What type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis?

• evidence from landforms
• evidence from fossils
• evidence from human remains
• evidence from climate

A place where two plates slide past each other, moving in opposite directions, is known as a

• transform boundary
• divergent boundary
• convergent boundary
• rift valley

What were magnetic stripes on the ocean floor used to show?

• the seafloor was spreading outward from the mid-Atlantic ridge
• the seafloor was spreading inward toward the mid-Atlantic ridge
• the seafloor was effectively stationary
• natural magnetic rocks always form in the mantle of the Earth

Which of the following DOES NOT provide evidence that the continents were once joined together?

• fossils of the same reptiles found on different continents
• different continents having rocks of the same age and type
• coastlines of some continents matching up
• ancient maps left by early humans showing only one large continent

Who first proposed the theory of continental drift?

• John Tuzo Wilson
• Harry Hess
• Alfred Wegener
• Robert Dietz
