A convergent: subduction boundary is where two plates come together and one goes under the other. A convergent: subduction boundary is where two plates come together and one goes under the other.

10. Plate Boundaries 300 What kind of boundary creates mountains? Describe that boundary. What kind of boundary creates mountains? Describe that boundary. A convergent: buckling boundary makes mountains; that is when two continental plates come together and they both push up. A convergent: buckling boundary makes mountains; that is when two continental plates come together and they both push up.

11. Plate Boundaries 400 Explain how new sea floor/crust is created. Explain how new sea floor/crust is created. New sea floor/crust is created at a divergent plate boundary where two plates pull apart. When the plates pull apart, magma from the mantle comes up, cools, and hardens into rock/crust. New sea floor/crust is created at a divergent plate boundary where two plates pull apart. When the plates pull apart, magma from the mantle comes up, cools, and hardens into rock/crust.

12. Geologic Activity 100 What type of geologic activity is associated with transform boundaries? What type of geologic activity is associated with transform boundaries? Earthquakes Earthquakes

13. Geologic Activity 200 Explain WHY earthquakes occur at transform boundaries. Explain WHY earthquakes occur at transform boundaries. When two plates rub together, it causes friction and pressure. When the plates slip, it causes the earth to shake.

14. Geologic Activity 300 Name three types of geologic activity that happen at convergent (subduction) boundaries. Name three types of geologic activity that happen at convergent (subduction) boundaries. trenches, earthquakes, and volcanoes trenches, earthquakes, and volcanoes

15. Geologic Activity 400 Besides new crust, what else is created at a divergent boundary in the ocean? Besides new crust, what else is created at a divergent boundary in the ocean? What is created at a divergent boundary on a continent? What is created at a divergent boundary on a continent? Divergent boundaries in the ocean = mid-ocean ridges and volcanoes Divergent boundaries in the ocean = mid-ocean ridges and volcanoes Divergent boundaries on continents = rift valleys Divergent boundaries on continents = rift valleys

16. Evidence100 Scientists believe that million of years ago all the continents were connected – what was that large land mass called? Scientists believe that million of years ago all the continents were connected – what was that large land mass called? Pangaea Pangaea

17. Evidence 200 Scientists have found fossils of the same animal species on multiple continents, but the animal could not swim, so how did the animal get to the different continents? Scientists have found fossils of the same animal species on multiple continents, but the animal could not swim, so how did the animal get to the different continents? If the animal wasn’t able to swim to the different continents, this suggests that the continents must have been connected. If the animal wasn’t able to swim to the different continents, this suggests that the continents must have been connected.

18. Evidence 300 Scientists know that plants and animals need a warmer climate to survive, yet we’ve found fossils on Antarctica – how’s that possible? Scientists know that plants and animals need a warmer climate to survive, yet we’ve found fossils on Antarctica – how’s that possible? This suggests that long ago Antarctica used to be located closer to the equator and had a warmer climate. This suggests that long ago Antarctica used to be located closer to the equator and had a warmer climate.

19. Evidence 400 Give three specific pieces of evidence that led scientists to infer that South America and Africa used to be connected. Give three specific pieces of evidence that led scientists to infer that South America and Africa used to be connected. The shape of South America and Africa look like they fit together The shape of South America and Africa look like they fit together Animal fossils such as Cynognathus or Mesosaurus Animal fossils such as Cynognathus or Mesosaurus Plant fossils such as the Glossopteris Fern Plant fossils such as the Glossopteris Fern

20. Rocks100 What are tiny pieces of rock called? What are tiny pieces of rock called? sediment sediment

21. Rocks 200 Which type of rock is formed from molten lava that cools and hardens? Which type of rock is formed from molten lava that cools and hardens? Igneous Igneous

22. Rocks 300 Explain what sedimentary rock is. Explain what sedimentary rock is. Sedimentary rock is made of layers of tiny pieces of rock (sediment) pressed together or compacted.

23. Rocks 400 What are metamorphic rocks? What are metamorphic rocks? Metamorphic rocks are made when sedimentary or igneous rocks are CHANGED by heat and pressure. Metamorphic rocks are made when sedimentary or igneous rocks are CHANGED by heat and pressure.

24. Rock Cycle 100 What is it called when material is added to an area? What is it called when material is added to an area? deposition deposition

25. Rock Cycle 200 What is it called when sediment is pressed together over time to (it turns sediment into sedimentary rocks)? What is it called when sediment is pressed together over time to (it turns sediment into sedimentary rocks)? compaction compaction

26. Rock Cycle 300 Explain what erosion/weathering is. Explain what erosion/weathering is. Erosion/weathering is when rock is worn down by water or wind. Erosion/weathering is when rock is worn down by water or wind.

27. Rock Cycle 400 Explain how a sedimentary rock could turn into a igneous rock. Explain how a sedimentary rock could turn into a igneous rock. First, the sedimentary rock needs to heat and melt into magma. Then, it would need to cool and harden into igneous rock. First, the sedimentary rock needs to heat and melt into magma. Then, it would need to cool and harden into igneous rock.

28. Final Jeopardy Below is a map that shows geologic activity (volcanoes and earthquakes) – make an inference about where this geologic activity is happening. Below is a map that shows geologic activity (volcanoes and earthquakes) – make an inference about where this geologic activity is happening. The majority of the volcanoes and earthquakes appear to occur on or near plate boundaries – where two tectonic plates meet.
