1: Why do some parts of the ocean turn over, while others do not?
2: What are the global consequences of all the fires burning in the Northern Hemisphere (i.e. Western U.S., Russia etc.) Would there be any connection with the amount of rain for the season, since water vapor must have something to condense on. THANK YOU
3: How come the water in the Bahamas and in Hawaii is so clear and in Santa Barbara and Monterey the water is not?
4: I have several questions: Here in the US, we are taught that there are 7 continents, but I have met several internationals who say there are only 5. Which is count is correct? Second, in which continent does the Middle East lie (and is Egypt considered part of the Middle East)? Relatedly, which countries consitute the following: the Near East, the Middle East, and the Far East (and according to whom?) Is Central America considered part of North America or South America?
5: On many maps and globes, there is a figure 8/infinity symbol--vertically placed in the middle of the map. We have a geochrom map in our library. A dark sphere traverses the "infinity symbol." What does this represent? Please explain so that we can explain it to our third graders and their parents.
6: On the geochrom map, when it explains time zones, it shows there being some parts on the globe that have fractional parts of an hour, for example, the center of Australia is the time zone of Japan +30. This is new to us. Why do some parts of the globe have fractional parts of an hour instead of one complete hour? Thank you very much.
7: What do the temperartures along the equator measure?
8: When I was in Germany I watched the sunset and the sun went down really slowly. Then I came back to Goleta and I watched the sunset and the sun went down really fast. Why is that?

31: What occurs at plate boundaries that are associated with seafloor spreading?
32: Was the Santa Barbara Channel formed by a glacier or was it formed by plate tectonics? Also, how did it become so deep because I was told it might have been formed by Santa Clara river draining into the channel over millions of years? Thank you very much
33: Desertification is increasingly becoming more of a problem, is there a way to reverse it once the damage is done.
34:

We are currently doing a research project on how the deposition of gold in California helped shape the history of California.

We are wondering how much gold & silver is left to be mined in California. I'm assuming it's a lot but I just can't remember how much. Also, Where are most of the gold mines in use currently in California, like The Mojave Desert?

Where is gold currently being deposited around the world today? I've heard, as a geology teacher, that it's currently being deposited in the Long Valley Caldera but are there other areas in the world?


35: Which are the types of plate boundaries where volcanic eruptions can occur?
36: Why doesn't Europe have a cold climate more similar to that of Alaska and northern Canada?

39: Is it possible that all the continents will move back together and form Pangaea again?
40: Which pole is colder, north or south?
41: It has been said that some polar bears spend part of the year on land in warmer climates. If this is the case, then why can't we move the polar bears that are drowning in the arctic climates, due to melting ice caps, and bring them to the land to adapt like some polar bears do year around?
42: Thanks for your help on my previous questions, this is another related question that I was also wondering about: How can one determine the range of destruction (how big of an area will be destroyed, etc...) of an object that would impact the earth? In large scale situations, what would be the affects for countries hundreds or thousands of miles away? How could you know if a country far away from the impact would be safe - or not?
43: In class we learned that the density of tectonic plates determines which converging plate will subduct. What would happen in the case of two oceanic plates that have equal density? Would the both try and subduct, resulting in a big v- formation / trench thing? Are there any locations on earth where two identically-dense oceanic plates meet? Thanks.
44: I've heard that along the 101 between Ventura and Carp that you can see the shelves created by uplift. There are obvious shelves at Mussel Shoals but I can't tell if they are due to freeway construction [like at the Rincon]or not. Can you give me lat/long for the location of the shelves due to uplift please! Thanks!

135: What is an ecosystem and what is it made of?
136: Geology says high mountain peaks are formed in subduction zones where a continental plate riding on an oceanic crust meets a similar plate. This is also as a result of the seafloor spreading that has to be compensated for, due the fact that the Earth has a unit Mass and Area. My question here is: why has the mountain range (especially Everest) not extended it's peak indefinitely, since a new seafloor is created at the mid oceanic Ridge? Thank you

184: If stingrays like warm water which we had in Ventura a month ago, where do they go now that the water is like 55F, cold!? I know they liked the water because I got stung by one.
185: What happens when two oceanic plates converge?
186: How did fossils provide evidence for continental drift?
187: As a physics teacher I've always been puzzled by the movement of weather systems from west to east. Seems to me the rotation of the Earth and the low frictional drag on the atmosphere would result in a east to west movement?
188: What is the hottest temperature ever recorded in a desert?

Could you shed some light on this and how the climate will change as a result of deforestation in that area? Thank you!
194: Global warming is causing the melting of glaciers. Consequences of this is that sea level is increasing but it is said that rainfall is decreasing in spite of increasing due to high evaporation rate made by increasing in the temperature of sunlight reaching Earth that causes evaporation. Why is it so?
195: How will the melting of the glaciers on Greenland and Antarctica affect global circulation?
196: I'm a teacher and I've discussed this question with my department and we haven't come to a consensus. Is it possible for a sedimentary rock to become an igneous without becoming metamorphic first? Since melting is not instantaneous, would it technically become metamorphic before igneous, even if melting happens rapidly?
197: Did dinosaurs exist in Los Angeles?
198: Can moss determine direction when you are lost?
199: Hi,I just thought of one reason why ships and aircraft sink in Bermuda triangle. I thought that probably because ships are made up of metals and magnets attract metals, is there the possibility that there are magnets inside the sea that are capable of attracting ships? In that case, I don't know how magnets came there.
200: Can you explain me the reason for the strong earthquake in Italy a few days ago? Why this earthquake did destroy so much?

202: How do tornadoes form?
203: Why is the ocean so salty?
204: Will the prolonged drought in California affect the propagation of different waves during an earthquake? Would the significant drop in soil moisture make the strata more or less rigid thereby affecting the velocity of the different waves associated with the quake? This question was asked by a colleague of mine while researching the Earth Science standards for Next Generation Science Standard, so it's more advanced than a normal question from a high school student!
205: Is the Coriolis force affected by climate change on Earth?
206: If you deliberately drilled a huge hole at the North Pole, and allowed all the earth's magma to spill out, as the earth tilted, could the weight shift, cause the earth to "flip" upside down, thus causing a reversal? Sounds plausible to me.

208: What would be the devastation of the most powerful nuclear bomb dropped on New York City, within 2 miles, within 6 miles, within 10 miles, within 30 miles?
209: Based on a research in Norway, "... the Barents Sea and what they found could offer a viable scientific reason behind the Bermuda Triangle phenomenon. 'Multiple giant craters exist on the sea floor in an area in the west-central Barents Sea ... and are probably a cause of enormous blowouts of gas,' researchers told the Sunday Times. The craters in question were a half a mile wide and 150 feet deep, the Daily Mail reports. The researchers think methane leaking up through natural gas deposits caused the craters, meaning there wasn't just the gradual erosion but explosions of gas as well." Do you believe this could be a possible explanation behind the Bermuda Triangle phenomenon?
210: What are the ocean currents that affect the United States?
211: Do steelhead spawn in the streams on the channel Islands? Santa Cruz Island has perennial streams/creeks that have never been barricaded so the fish's reproductive behavior has never been affected (like what we see on the mainland). If they do spawn there why don't we ever hear about it? If they do not spawn there, why not?
212: I saw a picture yesterday on the newspaper online of lava flowing from rocks in Hawaii. How is this possible?
213: The current that runs along the East Coast eventually reaches England. England is at the same latitude as far north as Canada and Northern Europe, yet it has a much more mild climate. Then why does England has a milder climate?
214: How can grass and trees grow on Hawaii if all Hawaii is molten lava dried and hardened?
