12.  What evidence, besides seismic waves, do scientists have to support our current layered model of the Earth’s Interior?

  1. Scientists have drilled holes down through the crust and mantle to the outer core.
  2. Parts of the earth’s oceanic crust and mantle have risen and become exposed at beaches.
  3. The fact that the magnetic poles of the Earth flip every 10,000 years or so as captured in the alternating patterns of magnetic rock on the ocean floor.

****************** Base your answers to questions X–Y on the diagram below. ***************** The diagram shows a cross-section of the earth with the arrows representing one possible pattern of thermal convection in the Earth’s mantle.

13.  What is one of the causes the movement of the mantle material?

a. heat is transferred from the core to the mantle material

b. heated mantle material becomes less dense and rises

c. cooled mantle material becomes more dense and falls

d. all of the above

e. none of the above

14.  Which of the following is NOT a source of the Earth’s internal heat?

a.  Decay of radioactive elements

b.  Original heat of the Earth’s formation

c.  Heating by the impact of meteorites early in Earth’s History.

d.  Coal-burning stove

15.  What is one cause of the movement of lithospheric plates on the mantle?

e.  Gravity pulls the denser, cooler ocean plates down into the mantle at subduction zones.

f.  Gravity pulls the less dense, cooler continental plates down into the mantle at subduction zones.

g.  Gravity pulls the denser, cooler ocean plates down into the mantle at divergent boundaries.

h.  Gravity pushes the less dense, cooler continental plates up above the mantle at subduction zones.

**********This diagram shows a cross section with TWO subduction zones. Use the diagram to answer questions X-Y**********

16.  This diagram shows two different types of volcanoes. What is DIFFERENT about the two types of volcanoes?

  1. One is formed in water and the other is formed on land.
  2. One is formed from rising magma while the other is formed by falling magma.
  3. One is formed near a subduction zone while the other is formed far away from a subduction zone.
  4. One is formed at a convergent plate boundary while the other is formed at a divergent plate boundary.

17.  This diagram shows two different subduction zones. What do they have in common?

  1. Both involve a convergent plate boundary.
  2. Both involve oceanic crust sinking below continental crust.
  3. Both involve the formation of new oceanic crust.
  4. Both involve the formation of an island arc.

18.  This diagram shows the formation of mountains along the edge of a continent where an oceanic plate is subducting beneath a continental plate. This happens several places on the globe. There is ONE place in the world where a continental plate is converging with another continental plate to form mountains. Where is this location?

  1. Cascade range in Oregon and Washington where the Pacific Plate is converging with the North American Plate.
  2. Andes Mountain Range in South America where the Nazca Plate is converging with the South American Plate.
  3. Himilayas Mountain Range where the Indo-Australian Plate is converging with the Eurasian Plate.
  4. Rift Valley of eastern Africa where the African Plate is splitting in two.

19.  Which of the following does NOT occur at a subduction zone?

  1. As an ocean plate crashes into a continental plate and sinks, some of its acquired sediment is scraped off and gets added to the edge of the continental plate, causing the continent to grow in size.
  2. Rising magma above the subduction zone cools and forms igneous rock that gets added to the continental plate – making the continent grow in size.
  3. Oceanic crust that gets subducted under the continental plate melts, causing that part of the oceanic plate to be destroyed.
  4. Rising magma from the asthenosphere forms new oceanic crust along mid-ocean ridges.

Possible Open Response

1.  Use the information from Chart B: The Earth’s Layers to draw and label a cross-section of the Earth, showing its four major layers: crust, mantle, outer core, inner core.
