5 Matching questions

  1. Ice Cores
  2. Convection Currents
  3. Transform Boundary
  4. Chemical Weathering
  5. Evolution
  1. a The constant rising and cooling of magma in the Earth's mantle. The heat from the inner core is what causes this motion. They cause plate movement in earth's crust.
  2. b Long cylinders of ice used to study Earth's atmosphere. Trapped gases and dust inside the ice cores tell scientists when volcanoes erupted and how the climate used to be.
  3. c The gradual change in a species over time.
  4. d When two plates slide past each other. They cause earthquakes.
  5. e The process by which the chemical make-up of a rock changes.

5 Multiple choice questions

  1. A fossil embedded in a rock layer. The age of the rock layer is the same age as the fossils embedded in it.
  2. A gap in a rock layer. It reduces scientists understanding of Earth's history because it's a missing piece of information.
  3. The DENSEST layer of the Earth that is made of a solid ball of iron.
  4. The next dense layer of the Earth that surrounds the inner core. It's made of a liquid ball of iron.
  5. The era of the Geologic Time Scale when the dinosaurs both appeared and became extinct.

5 True/False questions

  1. Subduction BoundaryWhen two plates move towards each other, but the dense oceanic crust sinks under the continental crust. They cause volcanoes.

          

  2. Divergent BoundaryWhen two continental plates move towards each other. They cause mountains.

          

  3. MantleThe thickest layer of the Earth. It is where convection currents happen.

          

  4. Survival of the FittestOrganisms that are the fittest will live the longest and produce the most offspring. Then they pass their favorable characteristics onto their offspring.

          

  5. Paleozoic EraThe era of the Geologic Time Scale when life first appeared in the oceans. It came after Precambrian Time.
