Name/Number ______________________________________ 2016-17 6th Grade Earth Science Final Exam Review Guide. This review guide must be submitted on the day of the Final Exam. The completed review guide will count as a 4th quarter test grade. Describe at least 4 pieces of evidence that led Wegener to suggest the theory of Continental Drift. Wegner noticed that the continents fit together like a puzzle. He also noticed that if you put the continents together, the mountain ranges, mineral deposits, and ancient animal fossils matched. He also noticed that glacier scars exist in places that are now tropical and that tropical fossils exist in polar places. This indicated that the continents have not always been in the same place. Why was Wegener’s theory initially rejected? Wegern’s theory was initially rejected because he couldn’t describe how or why the continents moved. Describe how the granite of a mountain could change into sandstone, a sedimentary rock, and then into quartzite, a metamorphic rock. In your paragraph, underline the following words: weathering, erosion, deposition, sediment, heat and pressure and cementation. The granite of a mountain undergoes the weathering effects of rain and wind, breaking the granite into tiny bits of sediment which are carried away through erosion and then might be deposited on the floor of an ocean. Over time, as more and more sediment is deposited into the same place, the sediment begins to become squished down or compacted and is eventually cemented together to form sedimentary rock. If this sedimentary rock continues to remain underground and is pressed farther below the surface, it might undergo enough heat and pressure to turn it into quartzite, which is a metamorphic rock. List and describe the three processes that work together to wear down and build up Earth’s surfaces. Weathering breaks it down. Erosion carries it away. Deposition drops it down and builds it up.

Briefly explain how a nuclear power plant can be used to generate electricity. In your paragraph, underline the following terms: fission, control rods, turbine, steam, energy,
The uranium atoms in a nuclear power plant undergo release heat energy when they undergo nuclear fission, which is the splitting of an atom. Control rods slow down the process of fission to help avoid explosions. The heat energy causes water to boil and produce steam. The steam then rises which causes a turbine to spin. The spinning turbine causes magnets to rub together which creates electricity.
How do mid-ocean ridges form?
Mid-Ocean ridges form when the convections currents in the mantle cause the lithosphere to break apart at a divergent boundary under the ocean. As the plate splits apart at the divergent boundary, magma rises from the mantle, creating underwater volcanic mountains know at mid-ocean ridges.
How do deep-ocean trenches form?
Deep ocean trenches form when two oceanic plates are pushed together by convection currents in the mantle. When these two plates collide at a convergent boundary, the older, more dense oceanic crust subducts below the newer oceanic crust and forms a deep underwater canyon known as a deep-ocean trench.
What are three features of a habitable planet?
1) Liquid water
2) Clear atmosphere
3) Orbit in the “goldilocks zone” where it is not too hot and not too cold
Be ready to answer multiple choice questions related to the following concepts.
Hurricanes form over what type of water?
Hurricanes form over warm ocean water that is at least 80 degrees F.
According to theory of plate tectonics, what causes the plates to move?
Convection currents cause tectonic plates to move
Where are thunderstorms more likely to occur?
Thunderstorms are most likely to occur where a moist warm air mass collides with a cool air mass. Florida has more thunderstorms than California because summers in Florida are humid and summers in California tend to be dry.
How might weathering and erosion affect mountains or other land features?
Weathering and erosion will cause sharp jagged mountains or edges of craters to become smooth and more rounded over time.
