PS #4 Plate Tectonics Pre Test

What is the Theory of Continental Drift?

• New continents are continually being created

  and destroyed.

• The layout of the continents is the same today

  as it has always been

• The continents have always been separate but

  may one day drift together to form a single

  continent

• All the continents were once one continent that

  broke up and drifted apart over hundreds of

  millions of years

What type of tectonic plate boundary involves a collision of plates?

• transform

• divergent

• convergent

• obstructive

What type of boundary exists when 2 plates are pulling apart?

• Convergent

• Transform

• Obtrusive

• Divergent

Rift Valley is a feature of what plate boundary?

• Obtrusive

• Divergent

• Transform

• Convergent

When two convergent plates come together where the denser one is forced under back into the mantle

• reduction
• conduction
• subduction
• convection

What forms when two continental, convergent plates push together?

• volcano
• mountain
• earthquakes
• island
