continental drift review Plate tectonics and continental drift review

Mid-ocean Ridge Mountains Islands Trench Trench Subduction Subduction Magma Rising 1. Label the diagram above with the terms,

A B C D 2. Which is older? The mid-ocean ridge (A) or the abyssal plain (the flat ocean floor) (B) 3. Which is older? The Islands (D) or the continental shelf (C) 4. Which is older? The mid-ocean ridge (A) or the Islands (D) B Continental shelf Islands

Convergent oceanic/continental plates 5. Look at the diagram, at what type of plate boundary would you expect to find volcanoes and earthquakes?   Convergent oceanic/continental plates 6. At what plate boundary would you expect to find mountains and earthquakes? Convergent continental plates 7. At what plate boundary would you expect to find islands? Convergent oceanic plates 8. The youngest rocks on the ocean floor are found Mid Ocean Ridge 9. The oldest rocks on the ocean floor are found Subduction zone

10. The subduction zone occurs at what plate boundaries?   11. The trenches occur when?   12. The boundary between two colliding continental or crustal plates is called a The boundary between two plates that slide past one another is called a Convergent Ocean /Ocean or Ocean/Continental Subduction happens Convergent boundary Transform boundary Where plates slide past one another, the result is   15. The boundary between two dividing crustal or oceanic plates is called a 16. Mountains formed by the collision of the Indian plate and the Eurasian plate are the     Volcanic mountains formed when the Nazca and the South American plate collide are the 18. Name the theory that the earth's crust is made out of plates that move due to convection currents in the mantle. A transform fault Divergent boundary Himalayan mountains Andes Mountains Plate tectonics

19. Draw a Divergent boundary 20. Draw a convergent boundary 21. Draw a Transform boundary

Which theory states that the continents were once joined in a large land mass? 23. Name the examples of evidence for continental drift What examples could not be used for continental drift? Shifts in Earth’s continents most likely caused a change in Earth’s Fossils of tropical plants found in Antarctica indicate that 27. South America was originally connected to Continental Drift theory Fossils, Rocks, Puzzle Living plants and animals Climate It was once much warmer Africa 28. A large land mass that contained all the continents is called     29. If you are afraid of earthquakes or volcanoes, where should you choose to live? Pangaea In the middle of a plate far from the edges

Where do tectonic activities occur? 31. Why did Hawaii form in the middle of the Pacific plate? 32. The California Fault line that causes earthquakes is the 33. The ridge that runs down the length of the Atlantic Ocean where the plates are diverging is the 34. The Island Arcs of Japan are caused by Along plate boundaries It is a hot spot in the earths crust San Andreas Mid Atlantic ridge. The Eurasian and Pacific plates converging

Pangaea! Divergent oceanic Write the name of each type of plate action that forms the surface feature: 35. San Andreas Fault __________________________________________ 36. Mid-Atlantic Ridge ___________________________________________ 37. Himalayan Mountains ________________________________________ 38. Island Arc of Japan __________________________________________ 39. Islands of Hawaii ____________________________________________ Transform Divergent oceanic Convergent continental/continental Convergent Oceanic/Oceanic Hot Spot 40. What is the name of the super continent on the left Pangaea!

44. What process occurs at this sort of boundary? Mid Divergent 41. The model below is an example of a boundary formed by two oceanic crust. Section A Section B Section C Oceanic Crust Oceanic Crust Fill in the with ARROWS to show the direction of movement of each plate, then fill in the sentences below. ocean ridge 42. Section A is an example of a ______-____________ ______________. This can be described as a ___________________ boundary.   43. What sort of boundary would occur along sections B and C? ____________________________________ 44. What process occurs at this sort of boundary? Mid Divergent convergent Subduction

45. What process occurs within the mantle that causes the movement of plates? Convection! 46. How do you know that something is in motion? Be sure to include the term reference point in your answer It has changed it’s distance from the reference point.
