What role does Equity theory play in the new system?

Oceanography help please?

• if you can answer ANY of these question you would help a lot :) thank you! Sediments 1. Sediment found on the continental slope would be best categorized as 2. Which sources would be expected to contribute to sediment at the bottom of the Mariana Trench? 3. Which common autotroph contributes to siliceous ooze? 4. Where would you expect to find a greater amount of biogenous sediment, in neritic or pelagic regions? 5. Neritic sediments are much thicker on the Atlantic coast than on the Pacific coast. Use what you know about continental margins to explain. 6. Give three reasons for the high solubility of calcium carbonate in the deep ocean. Plate Tectonics 1. Tectonic plates are in constant motion. Why? 2. What is the mid-Atlantic Ridge and what role does it play in plate tectonics? 3. When oceanic and continental plates come together, what happens? Why? Identify the evidence we can observe from the earth’s surface to support your explanation. 4. For each type of plate boundary, describe the geologic activity you would expect and provide an example of where in the world you would expect to see a boundary of this type (see table 3.1) 5. There are two ways to classify layers of the earth – name them. 6. The asthenosphere in one classification system is part of which layer in the other classification system? 7. The crust in one classification system is part of which layer in the other classification system? 8. One method of classifying layers gives three, the other gives five layers. Name them. 9. On which layer do tectonic plates float? Topography 1. Compare and contrast island arcs and islands formed from hotspots. Include how they form as well as evidence used to determine the type of island. 2. Islands can be categorized as continental or oceanic. Name and describe three types in each category. 3. What is paleomagnetism and how does it support the theory of seafloor spreading? 4. Compare and contrast active and passive continental margins. 5. How does a seamount differ from a guyot? 6. What is an atoll and how does it form? 7. What is a submarine canyon? How does it form? 8. Name two ways in which granite differs from basalt. 9. Photosynthesis is not carried out near hydrothermal vents – why? What process is used instead to convert energy into a form that can be stored? 10. How do gulf, bay and cove differ? 11. Name three organisms commonly found near hydrothermal vents. 12. What are the three types of hydrothermal vent? How do they differ? 13. Where are hydrothermal vents typically located? 14. What happens when continental plates converge? 15. What forms where continental plates diverge? Geography (see map and discovery activity we did during the first week of class) 1. Be sure you can identify symbols on a blank map positioned on places we studied. (i.e. specific seas, passages, ocean, islands, continents) 2. Explain how a sea differs from a lake or an ocean 3. Provide relative sizes and distances for items we’ve studied: a. Average depth of the ocean and deepest point b. Express the deepest point of the ocean in inches (shows that you can do dimensional analysis problems) c. Height of tallest mountain d. Why is it most probable that the satellite due to fall today will land in the ocean? e. What are the largest and smallest oceans? f. Near which ocean are earthquakes most prevalent? Why?

• Answer:

  If you ask the ones you can not find yourself i will answer them for you.
