MCQ EOT Page 13

1. What did Wegener expect to find on opposite sides of the Atlantic Ocean?

A. Different types of animals B. Similar rock types C. Similar weather patterns D. Identical river systems

2. How does the similarity in volcanic rocks on the coasts of Africa and South America support Wegener’s theory of continental drift?

A. It shows that volcanoes erupt in patterns. B. It proves that oceans are shrinking. C. It indicates the continents were once joined. D. It suggests the continents have always been in their current positions.

3. What do identical rocks on the west coast of Africa and the east coast of South America suggest about the timing and location of past geologic events?

A. Volcanic activity was unique to Africa. B. South America and Africa experienced unrelated geologic events. C. A shared geologic event occurred before the continents drifted apart. D. These rocks formed after the continents had fully separated.

4. Which of the following continents was part of Gondwana?

A. Europe B. North America C. India D. Greenland

5. What evidence supports the idea that the continents in Gondwana were once joined together?

A. Similar climates across continents today B. Identical languages and cultures on different continents C. Matching rocks, mountains, fossils, and glaciation patterns D. The presence of deserts in all continents

6. How does the fit of continental shelves support the theory that Gondwana's continents were once joined? A. The shelves contain oil reserves used for dating the continents B. The matching shapes and boundaries suggest they fit together like puzzle pieces C. The shelves show evidence of current volcanic activity D. The shelves have different compositions, proving they never connected

MCQ EOT Page 34 7. Where does new oceanic crust form? A. At ocean trenches B. On continents C. Along mid-ocean ridges D. In the atmosphere

8. How does magma contribute to seafloor spreading?

A. It pushes continents apart by forming rivers B. It rises at mid-ocean ridges, cools into rock, and creates new oceanic crust C. It fills in ocean trenches to stop subduction D. It hardens in the atmosphere to form clouds

9. What is the relationship between mid-ocean ridges, ocean trenches, and the movement of continents? A. Continents are stationary while oceanic crust moves underneath B. Ocean trenches create new land that pushes continents C. Mid-ocean ridges form new crust that spreads outward, moving continents, while old crust sinks at trenches D. Continents break apart only when trenches collapse

MCQ EOT Page 36 10. What feature of seafloor topography supports the theory of plate tectonics? A. Deep valleys on continents B. Flat plains across oceans C. Mid-ocean ridges and ocean trenches D. Tall mountains in deserts

11. Why do mid-ocean ridges support the idea of plate tectonics? A. They show where plates crash together B. They are made of ice, proving climate change C. They are places where new crust forms and spreads apart D. They have fossils from every continent

12. What does the theory of plate tectonics explain about Earth’s surface? A. Earth's surface never changes B. It is made of one solid layer that doesn’t move C. It is made of moving plates that can build mountains and cause earthquakes D. Only continents move, not the ocean floor

13. Why can tectonic plates, even though they move slowly, cause major changes on Earth’s surface? A. They carry oceans across the planet B. They are heavy and move quickly across continents C. They are massive and have enough force to shape landforms like mountains and valleys D. They are connected to Earth's magnetic field

MCQ EOT Page 49 14. What is the place called where two tectonic plates meet? A. Hotspot B. Plate boundary C. Earthquake zone D. Crater 15. What typically occurs at a divergent plate boundary? A. Plates slide past each other B. Plates crash and form mountains C. Plates move apart, forming new crust D. Plates remain still 16. Which of the following is most likely to occur at a transform boundary? A. Volcanoes erupt as plates pull apart B. Mountains form as plates push together C. Earthquakes happen as plates slide past each other D. Ocean trenches form from rising magma

17. Why do convergent boundaries often form mountains or ocean trenches?

A. Plates carry water that shapes the land B. One plate sinks beneath another or they push upward when they collide C. Crust at these boundaries disappears instantly D. The plates melt and float to the surface

MCQ EOT Page 58 18. How were the Andes volcanic peaks formed? A. By earthquakes pushing up the land B. By volcanic eruptions caused by tectonic plates colliding C. By rivers carving through mountains D. By glaciers moving across the land

19. What tectonic process is responsible for the formation of the Andes volcanoes?

A. Divergent plates moving apart and creating new crust B. Oceanic plate sinking beneath a continental plate causing magma to rise C. Plates sliding past each other causing earthquakes only D. Plates remaining stationary with no movement

20. Which two tectonic plates are involved in forming the volcanic peaks of the Andes Mountains? A. Pacific Plate and North American Plate B. Nazca Plate and South American Plate C. African Plate and Eurasian Plate D. Indo-Australian Plate and Antarctic Plate

21. How was the Aleutian volcanic island arc formed?

A. By the divergence of two continental plates B. By the subduction of one oceanic plate beneath another oceanic plate at a convergent boundary C. By the sliding of two plates past each other at a transform boundary D. By erosion of existing mountains

22. The Aleutian volcanic island arc formed because the Pacific Plate is subducting beneath which plate?

A. Eurasian Plate B. North American Plate C. South American Plate D. African Plate

23. Mount Shasta in the Cascade Range was formed because an oceanic plate is subducting beneath which type of tectonic plate?

A. Oceanic plate B. Continental plate C. Transform plate D. Divergent plate
