Tranform Plate boundaries _______________ each other:

  1. slide past
  2. move towards
  3. move away from

If the Earth's plates move 1.5 inches each year, approximately how many inches will they move in 36 years?

  1. 25 inches
  2. 58 inches
  3. 54 inches

What is the best evidence supporting the theory of the Supercontinent?

  1. similar rock formations
  2. similar plants
  3. similar glacial scratches

Which volcanoes have layers of cinder between layers of lava?

  1. cinder cones
  2. composite cones
  3. shield volcanoes

After a shield volcano erupts, it usually is:

  1. a little higher because most of the lava runs down the side of the volcano
  2. lower because the top of the volcano will cave in
  3. a lot higher because most of the lava piles up around the vent

Composite cones are often bigger than Cinder Cones because:

  1. they are older and have more time to grow
  2. the hard lava keeps them from wearing away fast
  3. they grow were there are already mountains

Mt. McKinley, in Alaska, is one of the world's highest volcanoes. From its size we can tell that:

  1. everything in Alaska is big
  2. Mt. McKinley is a Cinder Cone
  3. Mt. McKinley is not a Cinder Cone
