Paleozoic Review

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 is Pangaea?

• The name of a German scientist. 
• The final supercontinent. It formed during the Permian and broke apart during the Mesozoic
• Another name for continental drift
• The name of an ancient fossil. 

Which type of evidence was used by Alfred Wegener to support his continental drift hypothesis?

• evidence from landforms such as mountain ranges and rock types

• evidence from fossils that couldn't have swam across the oceans

• evidence from human remains

• climate change evidence such as glaciers and tropical fossils

• the puzzle-like fit of certain continents

Which process does NOT cause plate tectonics?

• convergent-subduction boundary (slab pull)
• divergent boundary (ridge push)
• rotation of the Earth on its axis
• convection currents in the mantle 

Most geologists think that the movement of Earth's plates is caused by

• conduction
• earthquakes
• convection currents in the mantle
• Earth's magnetic field

The geological theory that states that pieces of Earth's lithosphere are in costant, slow motion is the theory of

• subduction
• plate tectonics
• deep ocean trenches
• sea floor spreading

The process by which the ocean floor sinks beneath a deep ocean trench and back into the mantle is known as

• convection
• continental drift
• subduction
• conduction

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

The place where two plates come together is known as a 

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

A collision between two pieces of continental crust at a convergent boundary produces a

• mid ocean ridge
• deep ocean trench
• rift valley
• mountain range
