Earth Science

Dear Friends I am from Saraa School for Basic Education in the Sultanate of Oman and we want to exchange ideas about ways to get clean water to drink and how to guide people to conserve water… could you help me please

Hello! Tell me, which countries develops oil and gas deposits in Arctic now?

In just the same way that a core soil sample is taken of the Earth and archived for later analysis, how could the scientific community make use of 'test tube' atmospheric samples that are taken at altitude and physically returned to Earth. Would this be a viable support to current methods of remote sensing from the ground or satellite? Would this provide a valid archive of our upper atmosphere for historical analysis of ozone, volcanic ash, bacteria etc;

Hey everyone, I am working on my dissertation/ mapping project at the moment and i am about to start creating my neat copy geological map. Previously i have used powerpoint 2007 which basically did the job but had its limitations. ive heard that corel draw and adobe illustrator are pretty good but i wanted to get some feedback about any limitations the programs might have, so if you have any experience in either of the programs ive mentioned, or can recommend any other programs then i would appreciate it. Thanks

New Scientist, 7 January 2012 Forty years ago, a highly controversial study warned that we had to curb growth or risk global collapse. Does the prediction still hold, asks Debora MacKenzie AT THE beginning of the 1970s, a group of young scientists set out to explore our future. Their findings shook a generation and may be even more relevant than ever today. The question the group set out to answer was: what would happen if the world's population and industry continued to grow rapidly? Could growth continue indefinitely or would we start to hit limits at some point? In those days, few believed that there were any limits to growth – some economists still don't. …

By protected I mean in the following sense: I'm mainly interested in whether the US has the more park space for it's citizens to enjoy...than Canada and most of Western Europe. But, the more information the better...if anyone has a link to a list or some data to share. I'll be forever grateful. I've been looking for months, all I can find is % and only the top 10 countries or something. (of which, US is not included, fyi) So, I'm interested in a comprehensive type listing for area. If at all possible. Or whatever... your opinions and conjecture would be cool, too. Thanks.

How hard would it be to have a self sustaining human colonization, live and survive on Antarctica, without any outside support?

I'm writing a research paper, and one of the conditions is that one of my resources MUST be an academic article from an academic journal. My topic is Paper Recycling. I have been googling for the past half an hour and have been unable to find one, perhaps im looking in the wrong places. Could anyone maybe tell me about a free online academic journal please. Thanx.

Does the chlorine in swimming pools contribute to depletion of the ozone layer? It is known, for example, that chlorine reacts with acetone at room temperature to form chloroacetone, which could potentially find its way up to the ozone layer and cause problems. Consider this: a swimmer with diabetes, when going through ketoacidosis, can emitt acetone from their breath and skin. Should we be keeping people with diabetes away from pools? If elemental chlorine is too reactive to make its way into the ozone layer, what exactly does it react with that neutralizes it?

How common are underwater geysers? Under what conditions do the form? Where are they most common?

Could spherical deformation due to gravity pulling material to the center actually raise material near the surface with respect to material in the interior? Deep in the lithosphere, there is a zero displacement depth where the ratio k of horizontal stress to radial stress remains constant. Above this depth, k increases nonlinearly. Because of the free outer surface of the self-gravitating sphere, the material is able to expand in portions near the surface as compared with the material somewhat deeper. Could this be what uplifted the Colorado Plateau?

Hello, I live in the country in central Florida. The temperature drops to as low as 24 degrees F, maybe 15 nights during the winter months, and daytime temperatures are generally between 45 and 60. I'd like to build a greenhouse with plastic film that would be good for year round service, without using any electric or gas heating during the mild winters. I was thinking about driving a number of galvanized conduit pipes, with capped ends on the bottom of each pipe to keep them from filling with dirt, into the ground to allow heat to rise from the ground during winter months. I need to know if I'm deluded on this idea or if it's possible to do so. If it's p…

http://gizmodo.com/5862229/this-unreal-slow+motion-ice-tornado-kills-everything-it-touches?utm_medium=referral&utm_source=pulsenews So wait, is it actually a spinning column of water-ice? How does it kill everything it touches? How does the difference in pressure trigger it exactly?

SORRY WRONG FORUM... i will advise my question.. to this who is the best geologist in the world currently in your opinion

Why are density and seismic velocity inversely proportional to one another? Seems counterintuitive....

I understand, that 2.5 Gya, there was a major 'pulse' of continent creation, associated with the solidification, of magnesium-rich Upper-Mantle (UM) rock, under-plating the bottoms of crustal continents (Science News). Such under-plated rocks, e.g. kimberlite & komatite, derived from UM material that was then 500K warmer, than present epoch (ABC AU). Today, the UM is colder than its solidification temperature (Wikipedia). Is this accurate ? Does this mean, that the UM is enriched, in iron-rich olivines, if all the magnesium-rich olivines have under-plated continents ? At surface temperatures & pressures, the magnesium-rich material freezes at ~1900K, vs. ~…

"...have allowed us to interpret the 4kyr BP dust-event as the fallout of a distal impact-ejecta rather than a sudden drought. I ran across this recently, and wondered if there is any biblical or other historical/anectodal record of a global event such as is suggested by this evidence below, for an impact event. === I'm still studying soils and their (recently recognized) strong influence upon climate, but impact events affect climate too....

Hello everyone, My question is what happens to substances that contaminate deep ocean water and deep aquifers in the ground? For ocean water, my guess is that the pollutants enter the organisms found in the oceans and thereby enter into the food chain. A very vage answer, does anyone have a more solid answer? For deep aquifers, only source of pollution I can think of is deep injection wells. Now wht i dont knw is wht exactly HAPPENS to these pollutants, i get that they harm us and all but question is what happens to them? My paper is due in less than a day, any help would be appreciated. Thankyou.

I guess I am curious, given the fact that earthquakes, volcanoes, and other seismic events seem very unpredictable and I suppose this is the right place to ask someone knowledge. How much do we really know? How accurately can we hope to predict seismic events? Is it simply the need for more sensors and monitoring equipment, or do we have to break technology barriers?

I was curious to know how accurate those guys got it in the movie 'The Core' I know it's not the greatest fiilm in the world I think they could have done better with it however, I was wondering what people though about the accuracy of the theories of what the earth looks like as they travelled through the layers to get o the core. I also understand that what's under the surface it is all best guessed anyways but what do you guys think?

Would I be right in thinking that this Earth Science Forum is to ask questions but not to question? On a commercial beach I look at the pebbles a yard above the high tide mark, they are most interesting. From there up the beach the pebbles become more round, sphere shape, and the further down towards the sea edge, the shingle and grit become predominately rectangle, triangle shape, and further down the beach the sand becomes square? Surely this action should be the other way around, round at the shoreline and odd shaped at the top? Sunny clear water shores have sand whereas rough dirty shores have pebbles, again' surely this should be the other way around…

I already asked a similar question but now realise its scope was too narrow so I've broadened it to encompass the Earth System or 'Gaia' if you understand what that means. Imagine you are an ET scientist with the same tools, contemporary knowledge and resources but with no emotional affinity/identity* to the human race who has come to study the effects of human population growth on this blue/green rock's bio/physical/chemical mechanisms, resources and it's other inhabitants. What are they? *Same again here please, no politics or ethics and be prepared to pull out some evidence to support yourself if asked...this is the science section.

Hi all, I have been told to do a presentation on a topic that I have no idea about, and can't find much info on! I tried googling and all but it wasn't much help. The question is: Why does it take so long for deep ocean waters to circulate through the hydrologic cycle? What happens to substances that contaminate deep ocean water or deep aquifers in the ground? From the little knowledge i've got, I think the reason deep ocean waters take so long to circulate is because the deeper part of the ocean is colder. Colder because less sunlight reaches it. But, then it its colder shouldnt the density be less and it should rise to the top ?:s I could be wrong, as im pr…

Hi. About the age of certain rocks... If a rock is -say 1 million year old- What was the material/mineral/compound it is made of 1.1 million years ago (or before such date) ?
