Q: 33. What evidence did Wegener have for his theory of continental drift?

Correct Answer is: He knew that plant and animal fossils, as well as rock layers, matched on the two continents of Africa and South America.

Q: 34. What evidences do scientists use to support the continental drift theory?

Correct Answer is: rocks, fossils, climate

Q: 35. What kind of plate boundary causes old and heavy crust ( rocks ) to sink into the mantle ( subduction)?

Correct Answer is: convergent boundary

Q: 36. What kind of plate boundary causes sea floor spreading like the one causing the Atlantic Ocean to widen?

Correct Answer is: divergent boundary

Q: 37. What kind of plate boundary results to the formation of a fault line like the San Andreas fault in California?

Correct Answer is: transform or shear boundary

Q: 38. What kind of plate boundary results to the formation of a mountain range like the Himalayas and the Appalachian mountains?

Correct Answer is: convergent boundary

Q: 39. What kind of plate boundary results to the formation of a trench like the Marianas trench?

Correct Answer is: convergent boundary

Q: 40. What kind of plate boundary results to the formation of an Island arc?

Correct Answer is: convergent boundary

Q: 41. What kind of plate boundary results to the formation of most volcanoes?

Correct Answer is: convergent boundary

Q: 43. Where does sea floor spreading happen?

Correct Answer is: at the rift valley along the mid-ocean ridges

31. This process of old crust being pulled down and remelted is called:

sea floor spreading
drifting
plate tectonics
subduction

32. Volcanoes form at this boundary as plates pull apart

convergent
transform
transform and convergent
divergent

33. What evidence did Wegener have for his theory of continental drift?

He had no evidence.
He knew that plant and animal fossils, as well as rock layers, matched on the two continents of Africa and South America.
He explained how continents moved apart.

34. What evidences do scientists use to support the continental drift theory?

rocks, fossils, air
rocks, fossils, climate
rocks, water, ice
rocks, fossils, human beings

35. What kind of plate boundary causes old and heavy crust ( rocks ) to sink into the mantle ( subduction)?

convergent boundary
divergent boundary
transform or shear boundary

36. What kind of plate boundary causes sea floor spreading like the one causing the Atlantic Ocean to widen?

convergent boundary
divergent boundary
transform or shear boundary

37. What kind of plate boundary results to the formation of a fault line like the San Andreas fault in California?

divergent boundary
transform or shear boundary

40. What kind of plate boundary results to the formation of an Island arc?

divergent boundary
transform or shear boundary

41. What kind of plate boundary results to the formation of most volcanoes?

convergent boundary
divergent boundary
transform or shear boundary

42. What material forms new ocean floor?

sediment
magma
plates
rocks

43. Where does sea floor spreading happen?

at the rift valley along the mid-ocean ridges
at deep sea trenches
at the Ring of Fire
at the Pacific Ocean

44. Where is old crust melted back into magma?

at the mid-ocean ridge
along plate boundaries
at deep-sea trenches
volcano

45. Which of the following is not a TYPE of plate boundary?

convergent
transform
divergent
subduction

46. Who came up with the theory of sea floor spreading?

Alfred Wegener
Harry Hess
ancient Greeks
Albert Einstein

47. Why is a divergent boundary also called a constructive boundary?

Magma flows up between the plates and forms new crust.
Old ocean floor is re-melted into magma
Animals in the ocean construct nests there.
Pacific Ocean becomes wider

48. Why is Earth not growing in spite of sea floor spreading?

because of subduction in the Atlantic Ocean.
because of subduction in the Indian Ocean.
because of subduction the Pacific Ocean.
because of subduction in the Gulf of Mexico.

49. Why was Wegeners theory forgotten?

He could not explain how the continents could move.
It was not a good theory.
He did not publish his theory.
He did not have money.
