Unit 3 Lesson 3

Multiple Choice

What is the significance of Earth's plates in shaping the surface of our planet?

• They create weather patterns

• They help plants grow

• They move and interact to form mountains, earthquakes, and volcanoes

• They control the tides

Open Ended

What caused two neighboring islands to join together?

Multiple Choice

Which observation supports the idea that Africa and South America were once connected?

• The continents have similar climates today.

• The continents look like they fit together.

• Both continents are in the Southern Hemisphere.

• Both continents have deserts.

Open Ended

Observe the shapes of the continents and the information about the fossils found on each continent. Do you think that continents have always been in the same locations, or do they move?

Multiple Choice

Which of the following can fossils tell us about past environments?

• The exact age of the Earth

• Whether an aquatic environment existed

• The current climate of a region

• The number of continents

Multiple Choice

What evidence from landforms supports the idea that continents were once joined together?

• Continents have different types of rocks.

• Continental shelves fit together and matching mountain ranges are found on different continents.

• All continents are surrounded by water.

• Continents have the same climate.

Open Ended

What additional evidence and reasoning support the claim that the continents used to be a single landmass that broke up over time?

Open Ended

Explain how new technology has helped scientists understand the structure of the ocean floor.

Multiple Choice

Which feature runs along the entire middle of the Atlantic Ocean and is a giant continuous mountain range?

• Mid-Ocean Ridge

• Deep-Ocean Trench

• Continental Shelf

• Rift Valley

Multiple Choice

Which of the following statements about the Mid-Atlantic Ridge is correct?

• It is visible above water in Iceland.

• It is the deepest part of the ocean.

• It is located in the Pacific Ocean.

• It is a type of deep-ocean trench.

Open Ended

Describe the process by which a rift valley can become an ocean basin.

Open Ended

Explain how the age of sea-floor rock differs near mid-ocean ridges compared to near deep-ocean trenches. What evidence supports these differences?

Open Ended

Are the islands off the coast of Japan closer to a deep-ocean trench or a mid-ocean ridge? Use map evidence to support your answer.

Multiple Choice

Which of the following best describes tectonic plates?

• Large moving pieces of crust that fit together like a puzzle to form Earth’s outer shell

• Small stationary pieces of crust that never move

• Layers of magma beneath the Earth's surface

• Mountains formed by volcanic eruptions

Open Ended

Describe what happens when one oceanic plate sinks under another at a convergent boundary. What features can form as a result?

Multiple Choice

Which of the following statements about plate boundaries is correct?

• Divergent boundaries form volcanic islands and mid-ocean ridges

• Transform boundaries are where plates move away from each other and cause eruptions

• Convergent boundaries never form deep-ocean trenches

• All plate boundaries cause volcanic eruptions

Multiple Choice

What are the main differences between divergent, transform, and convergent plate boundaries in terms of plate movement and surface features?

• Divergent boundaries involve plates moving apart, forming rift valleys; transform boundaries involve plates sliding past each other; convergent boundaries involve plates colliding, forming mountain ranges.

• Divergent boundaries involve plates colliding, forming mountains; transform boundaries involve plates moving apart; convergent boundaries involve plates sliding past each other.

• Divergent boundaries involve plates sliding past each other; transform boundaries involve plates colliding; convergent boundaries involve plates moving apart.

• Divergent boundaries involve plates forming volcanoes; transform boundaries involve plates forming trenches; convergent boundaries involve plates forming lakes.

Multiple Choice

Which type of plate boundary is responsible for the formation of a rift valley?

• Divergent boundary

• Convergent boundary

• Transform boundary

• Subduction zone

Open Ended

In the area where the islands joined, what type of plate motion occurs and what surface features may form as a result?

Multiple Select

Which of the following are surface features that can result from plate motion?

• Deep ocean trench

• Lake of molten lava

• Himalaya Mountains

• Desert plain

Open Ended

How do convection currents in Earth's interior contribute to the movement of tectonic plates?

Open Ended

How does the joining of volcanic islands, like Nishinoshima and Niijima, help us understand the movement of Earth's plates?
