  • Which trilobite appeared last?
    Asaphidae
  • Just for fun: Are chickens cannibals?
    Yep. Who knew...
  • Weathered rock forms what natural resource?
    Soil
  • Faults and volcanoes are often found where?
    Near tectonic plate boundaries
  • How can deforestation and clear-cutting influence erosion?
    Without roots holding the soil place, water and wind will erode the top layer of soil.
  • The fossils deep within the Earth are usually the ______. The fossils closest to the surface are ________.
    Oldest, Younger
  • Where do you find most organic soil? (top layer of soil or 25 feet under ground)
    Top layer
  • The rocks closest to the ridge are _________ compared to the rocks farther away.
    Newer/Younger
  • What does this picture represent?
    Mid-Ocean Ridge
  • Describe the Mantle and it's state of matter.
    It is the thickest layer and the state of matter is Plasticity.
  • How do oceans impact the creation of a delta?
    Oceans slow the river down, which allows sediment to be deposited at the mouth of the river.
  • Plant fossils in Antarctica help to prove what???
    That Antarctica at one time had a tropical climate. It was near the equator.
  • The rocks farthest away from the ridge are _________ than the rocks closest to the ridge.
    Older
  • What is ice wedging?
    water fills the cracks in a rock, the water freezes, and breaks the rock.
  • Which trilobite appeared First?
    Auritimidae
  • __________ is broken up into giant moving plates.
    Lithosphere
  • What is D made of?
    Solid iron and nickle
  • Which layer of Earth is directly below the lithosphere?
    Asthenosphere
  • Ella throws a rock into the ground. The rock breaks into tiny pieces. Scientifically, what did Ella do?
    Physically weathered the rock.
  • What is reverse Erosion?
    Putting sediment back from where it came.
  • How do fossils give evidence that the continents are drifting apart?
    Same species of dinosaur on 2 different continents AND plant fossils in Antarctica
  • Which came first the chicken or the egg?
    The Egg... Duh.
  • What contributes most to the development of soil?
    Weathering of rock
  • What is C?
    Outer Core
  • Which part of a hurricane will erode away the beach?
    Rain, waves, storm surge, wind.
  • Which of Earth's layer has the lowest density?
    Crust
  • What is A?
    Crust
  • What is B?
    Mantle
  • What is the Lithosphere?
    Includes the crust and the top of the mantle. Made of giant tectonic plates
