o [pic]True

15. As rocks cool, they become denser and sink.

Fill- in- the-blank

21. The rocky, outermost part of the Earth, comprising the upper part of the mantle and the crust, is known as the _______. LITHOSPHERE

22. The reptilian fossils that Wegener used to help prove his ideas about plates are known as _______. MESOSAURUS

23. The process in which the sea floor separates and moves in opposite directions is known as _______. SEA FLOOR SPREADING

24. The exact point where an earthquake occurs below the surface is the _______. FOCUS

25. The point on the surface directly above an earthquake occurrence is called the _______. EPICENTER

26. The process of one plate diving under another plate is known as _______. SUBDUCTION

CHOOSE FROM THE CORRECT ANSWER

27. How does a convergent plate boundary differ from a divergent plate boundary?

o [pic]B) Convergent plates move towards each other and divergent plates move away from each other.

28. How did the presence of Glossopteris fossils support Wegener's idea of continental drift?

o [pic]C) The fossil plant has been found in Africa, India, Australia and South America and it is unlikely that a plant could have crossed the oceans. The continents must have been together at one point for this plant to disperse.

29. How does the global distribution of earthquakes relate to the plate boundaries?

o [pic]A) Earthquakes will basically “mark” the boundaries of the plates, wherever an earthquake is recorded that means that there is some sort of plate interaction.

30. The following arguments: The puzzle piece argument - The complementary arrangement of the facing sides of South America and Africa is obvious. Matching geology and matching fossils - Similar plant and animal fossils are found around different continent shores, suggesting that they were once joined. Glaciers - Widespread distribution of Permo-Carboniferous glacial sediments in South America, Africa, Madagascar, Arabia, India, Antarctica and Australia was one of the major pieces of evidence for the theory of continental drift. Continuous Mountain Belts – There is evidence for mountainous chains that belong to the same chain, that are now broken and dispersed along many continents.

o [pic]B) Were used by Wegener to start his hypothesis of continental drift.

31. What is the difference between Plate Tectonics and Continetal Drift

o [pic]c) Plate Tectonics is a scientific theory and Continental Drift is a hypothesis.

32. Volcanoes are associated with which type of plate boundaries?

o [pic]Convergent (continental-oceanic) subduction zone
