  1. Jeopardy

  2. Layers of the Earth for 100 What are the four layers of the Earth from Outermost to innermost? Crust, Mantel, Outer Core, Inner Core

  3. Layers of the Earth for 200 What layer of Earth contain the tectonic Plates that cause earthquakes and volcanic eruptions? The lithosphere

  4. Layers of the Earth for 300 What is the source of the magma that erupts from a volcano? The Mantle

  5. Layers of the Earth for 400 Plates of the lithosphere float on the… Asthenosphere

  6. Layers of the Earth for 500 This layer of Earth is composed mainly of liquid iron and nickel, it also creates Earth’s magnetic field. The outer core

  7. Plate Tectonics for 100 Seafloor spreading occurs because… Magma beneath the crust rises to the surface

  8. Plate Tectonics for 200 Where doearthquakes and volcanic eruptions most often occur? Plate Boundaries

  9. Plate Tectonics for 300 In seafloor spreading the youngest rocks on the ocean floor are located… At the Mid Ocean Ridge

  10. Plate Tectonics for 400 Magma from deep in the Earth’s Mantle rises toward the surface because… It’s less dense. And/or Convection Current.

  11. Plate Tectonics for 500 Ocean basin are formed under the surface of the water on the sea floor. What process forms an ocean basin? Two plates moving apart

  12. Dating Rocks and Fossils for 100 The law of superposition states… The oldest rocks/fossils are at the bottom and are progressively younger as you move toward the top.

  13. Dating Rocks and Fossils for 200 What could a geologist review to determine that two layers of the same rock were originally one layer? Law of superposition

  14. Dating Rocks and Fossils for 300 A layer of sandstone lies on top of a layer of limestone where a 300 million year old fossil is found. The sandstone must be _________ old • Younger than 300 million years

  15. Dating Rocks and Fossils for 400 3 layers of fish fossils: Layer A is at the bottom, B the middle, C at top. Underneath is a layer of sediment, which has also risen to make up the lake bank. How would you find the date for the oldest layer of soil. Date the layer of sediment

  16. Dating Rocks and Fossils for 500 Why do geologists use a variety of methods such the uranium lead and potassium-argon to date rocks? Different events in Earth’s history caused different rocks to form on Earth’s surface

  17. Weathering and Erosion for 100 How was the Grand Canyon formed? Physical Weathering by a large river

  18. Daily Double

  19. Weathering and Erosion for 200 What is the primary source of dissolved salts and mineral in the ocean? Mineral carried from the land by rivers

  20. Weathering and Erosion for 300 What type of climate promotes chemical weathering? One that is HOT and has HIGH amounts of precipitation

  21. Weathering and Erosion for 400 What does a sample of old mature soil contain? Several layers of different types of materials.

  22. Chemical vs. Physical for 500 A timber industry cut down 750 acres of pine trees across the street from a farm. The area is known for large wind gusts. What effect will this have on the farmer’s topsoil? Soil erosion will increase

  23. The Moon for 100 What causes tides? Gravitational pull of the Moon

  24. The Moon for 200 What would happen to the ocean if the Moon were twice as close as it is now? The tidal variations would be greater due to greater gravitational attractions

  25. The Moon for 300 Why do all of the planets and other astronomical bodies orbit the sun? The Sun exerts a strong gravitational pull

  26. The Moon for 400 What would happen if the moon were half the size that it is now? The ocean’s tidal variations would be smaller because the moon would exert less gravitational pull on Earth’s oceans.

  27. The Moon for 500 Gravity acts upon meteors from the asteroid belt between Mars and Jupiter. Where is this force most likely to pull the meteors? Towards Mars and Jupiter.

  28. Nature of Science for 100 Scientists collect evidence by making… Observations

  29. Nature of Science for 200 Logging is destroying forests that are home to the spotted owl, many scientists worry that the owl may become extinct. What is the primary threat to the spotted owl population? Loss of Habitat

  30. Nature of Science for 300 Which is NOT part of a well-designed experiment: Multiple trials A Control A Reproducible procedure Small Sample Size Small sample size

  31. Nature of Science for 400 Runoff from over-fertilized farmland reaches the ocean, allowing a type of algae to reproduce rapidly, the algae is toxic to local fish. How does the runoff effect the organisms of the area? The runoff is GOOD for the algae and HARMFUL to the fish.

  32. Daily Double

  33. Nature of Science for 500 A brick is cut into smaller pieces. What property do the small pieces have in common with the brick from which they came? Density
