Topic 4 Lesson 1 Test

Which of the following causes Earth's tectonic plates to move?

• Energy from the Sun
• Magnetic Pole Reversal
• Convection currents in the mantle
• Faults in Mountain Ranges

With all the sea floor spreading going on, why is the earth not expanding?

• Ocean Trenches

• Sea-Floor spreading

• mid-ocean ridges

• Subduction

Reorder the following: Lee knew that certain events occur to create new material in the process of sea-floor spreading. Place the steps into the correct order by placing the event that happens first at the left. Place the event that occurs last to the right.

• Molten maretial flows upward in a crack in earths crust

• The sea floor gradually becomes wider

• The molten material hardens into solid stris of rock on both sides of the crack

• The ocean floor on both sides of the crack mover farher away from the mid-ocean ridge

What type of plate boundary is this?

• Plate
• Divergent
• Convergent
• Transform

Which of the following is the name of the ancient supercontinent formed 280 Million Years ago.

• Pangea

• Gondwanda

• Laurasia

• Neverland

Which of the following is NOT evidence to support the theory of plate tectonics?

• Fossils
• Mountains
• Glaciers
• Sand Erosion

What geologic feature/event would you most likely to find at a divergent boundary between two pieces of oceanic crust?

• Rift Valley
• Mid-Ocean Ridge
• Island Arc
• Flat land

This layer is divided into pieces called tectonic plates.

• Mesosphere
• Asthenosphere
• Mantle
• Lithosphere

Which piece of evidence did Wegener use to prove continental drift?

• The shape of the continents
• Similar fossils found on separate continents
• Tree fossils found in odd places
• All of the above

As you travel from the inner core to the crust, how would temperature, pressure and density of the material change?

• The would all increase
• The would all decrease.
• Nothing, the layers are made of the same material throughout
• Temperature would decrease, but pressure and density would increase
