  1. Science – Constructive and Destructive Forces

  2. The center and hottest layer of Earth • Crust • Mantle • Pangea • Core • Erosion • Plate

  3. The process of dropping sediment in a new location • Fault • Deposition • Volcano • Weathering • Mantle • Landform

  4. “Supercontinent” on Earth millions of years ago • Mantle • Pangea • Mass Movement • Landform • Fossils • Erosion

  5. Process in which soil, sand, and sediment are formed • Fossils • Weathering • Lava • Volcano • Plate • Mass movement

  6. Rigid block of crust and upper-mantle rock • Mantle • Core • Earthquake • Crust • Plate • Deposition

  7. Physical Feature on Earth’s surface • Fossils • Landforms • Fault • Weathering • Continental Drift • Mass Movement

  8. Shaking of ground from energy release in the crust • Volcano • Erosion • Weathering • Earthquake • Plate • Landform

  9. Remains of traces of past life found in the crust • Fossils • Deposition • Magma • Continental Drift • Mantle • Pangea

  10. Middle layer of Earth • Crust • Fossils • Core • Lava • Mantle • Plate

  11. Hot, soft rock from the lower mantle • Fossils • Magma • Weathering • Core • Volcano • Fault

  12. Theory of how continents move over Earth’s surface • Pangea • Mass movement • Earthquake • Continental Drift • Erosion • Deposition

  13. Outer, very thin layer of Earth • Core • Crust • Deposition • Mantle • Fault • Pangea

  14. Place where pieces of the crust move • Core • Mantle • Erosion • Faults • Magma • Plate

  15. Downhill shifting of rock and soil because of gravity • Continental drift • Mass movement • Pangea • Magma • Volcano • Earthquake

  16. Opening in the crust through which lava flows • Earthquake • Continental Drift • Core • Volcano • Deposition • Landform

  17. Process of moving sediment from one place to another • Erosion • Fossils • Earthquake • Continental Drift • Mass Movement • Pangea

  18. What is the difference between constructive and destructive forces? • Constructive forces build up landforms, while destructive forces break down landforms

  19. What does a seismograph measure? • The intensity of an earthquake

  20. What happens when rocks rub against each other in running water? • They become smooth

  21. What happens when a volcano erupts? • Magma is forced out an opening in the Earth’s crust. It then becomes lava and hardens.

  22. The center of the Earth is extremely hot. Why, then, is it solid? • Because of pressure

  23. What can happen when water freezes inside the crack of a rock? • It can break the rock

  24. How can a dam prevent flooding? • By holding back and regulating the flow of water

  25. Where does the magma from volcanoes come from? • Deep inside the Earth

  26. What forces of nature can erode a rock? • Wind, rain, ice

  27. How does pollution speed up the erosion of rocks? • By causing acid rain, which dissolves rock faster

  28. What causes state or are to have a lot of earthquakes? • They are located on a fault line

  29. A new island formed in Iceland in 1963. What was most likely the cause of this island forming? • A volcano

  30. Give an example of a constructive force. • A volcano, fault lines cause a mountain to form, deposition forming a delta, etc.

  31. Give an example of a destructive force. • A volcano top blowing, landslides, mudslides, avalanches, erosion by wind, rain, or ice, etc.

  32. Why do scientists think there was originally one supercontinent that split up into the seven continents we now have? • The continents seem to fit together like a puzzle and fossils for animals from one continent have been found on other continents, suggesting they were once one.

  33. Which of the fossil layers shown is the most recent?

  34. The following pictures show the effects of wave action on a rock. Which would be the last picture if you put the pictures in order?

  35. What type of weathering is occurring in this picture? • water weathering – water is causing erosion by moving the sand • wind weathering – wind is causing erosion by moving the sand

  36. What type of weathering is occurring in this picture? Water is wearing away the rock by flowing over it.

  37. What do glaciers form? • Valleys (both U-shaped valleys and V-shaped valleys, depending on the size of the glacier.

  38. Explain how you could use ordinary items from your house to make a model of the Earth. • Answers will vary
