Earth’s Interior
| Question | Answer |
|---|---|
| Explain how pressure, temperature, and density change with depth. | As you travel deeper into Earth’s interior, pressure, temperature, and density all increase. If you travel from the core to the crust, these variables would decrease as you go towards the surface |
| Explain how scientists are able to determine the state of matter of Earth’s interior. | P waves can travel through all states of matter. S waves can only travel through solids. When detecting seismic waves, it is shown that S waves are stopped by something within Earth’s interior. |
| This means that there must be a liquid layer (outer core) that prevents the S waves from going through. | next question |
| Identify and explain four pieces of evidence that support Continental Drift. | Fossil evidence Rock layer order Glacial grooves “Puzzle like fit” Magnetic polarity Age of ocean floor |
| Draw and label Earth’s layers. Describe each layer. | Crust - thinnest layer; coolest layer Mantle - thickest layer; hotter Outer core - liquid core; even hotter; more dense Inner core - solid iron/nickel; hottest; densest |
| Fish fossils are discovered deep in the Namib desert. How does this discovery support the Theory of Continental Drift? | Fish obviously cannot survive in a desert, as they need water (duh). What this means is that this area was once likely a lake or ocean. In order for this to occur, the continents must have moved in order to change the climate and ecosystem. |
| Compare/contrast: Plate Tectonics vs. Continental Drift | Both these theories involve the Earth’s crust changing and/or moving Continental drift - theory that the landmasses have moved over time Plate Tectonics - theory that landmasses are moving around on pieces, called plates |
| What two layers compose the lithosphere? | Crust and UPPER mantle |
| What is Pangaea? | This is the name of the “supercontinent” that united all landmasses. |
| Explain how the magnetic polarity of the ocean floor can be used as evidence to support the Theory of Continental Drift. | As you travel from a mid ocean ridge, the magnetic polarity (+/-, or N/S) of the ocean floor flips. This “pattern” is found on both sides of a mid ocean ridge (similar bands on both sides have the same thicknesses) |
| Explain how age of the ocean floor changes with distance from a mid ocean ridge. | As you travel further from a mid ocean ridge, the ocean floor gets older. This means that as rock is created, it gets pushed away to make room for new rock |
