The second student tossed a coin onto the map, and it landed on Plate 6.

Which of these correctly identifies the plates that the students’ coins landed on?

• Plate 3 Plate 6

  North American Plate Eurasian Plate

• Plate 3 Plate 6

  Indo-Australian Plate African Plate

• Plate 3 Plate 6

  Indo-Australian Plate South American Plate

• Plate 3 Plate 6

  Nazca Plate South American Plate

When volcanoes form lava, or melted

rock rises from underground and

produces a bulge, how does the

eruption restore the Earth's

equilibrium?

• Pressure is released until external

  air pressure is greater than internal

  pressure, causing the system to

  become stable.

• Pressure continues to build until

  the bulge cools and becomes

  solid.

• Pressure is equalized restoring the

  system to a stable condition.

• Pressure is equalized but the

  system remains unstable.

in the location where the Alps were

formed?

• 
• 
•

Which force is responsible for the

movement of tectonic plates?

• gravity
