Earth Science

If ocean temperatures were rising along with air temperature, wouldn't this cause more evaporation and more cloud cover? If so, wouldn't the additional clouds reflect a great deal of sunlight back into outer space? Could this be a natural check on global warming? On the other hand, if cloud cover increased significantly and sunlight decreased accordingly, what effect would this have on plant-growth and the ability to process CO2 into O2? BTW, I started to post this on the thread about sea level and sea floor but it seemed too divergent.

effing craters: how do they work? just kidding. but seriously…I think we're all familiar with the method of plate tectonics if the continents drifted apart over millions of years creating new crust in their wake why are there those massive craters left over from millions of years ago, like the one off the coast of the Yucatán Peninsula? Shouldn't the new crust have filled that in? help me out with this, thanks, I keep wondering about it

If the earth was to rotate over say a period of 25 hours what would the impact be on night time and daytime temperatures? Would the relationship be linear, eg a 2 hour increase in rotation time would increase peak day time temperature on average by twice as much as a 1 hour increase?

I have a BA in communication from the University at buffalo. I live on LI and would like to go to an inexpensive school to complete all basic earth science courses I need to as well as the teacher certification classes. I am having difficulty getting some good advice so if anyone in this similar situation can help, please send a reply back right away. Thanks!

When reading a 40 year old "Life: nature library" book on earth i discovered a picture of what is labeled a "spiral of flame". it is where lightning ignites chemicals in the sky and has the appearance of a twisted cloth. this is supposed to be extremely rare. but i cannot find any information on it AT ALL, not even on the internet. i provided some links to the actual picture provided in the book. can you tell me the actual name of this phenomenon and if possible, links and references to where it may be found at? http://media-files.gather.com/images/d914/d902/d746/d224/d96/f3/full.jpg http://media-files.gather.com/images/d915/d902/d746/d224/d96/f3/full.jpg

Do the boundary of the Sahara desert goes through cycles ? Could there be as the Atlantic ocean gets warmer the desert will bloom ?

I was wondering about rock dating, and what methods are used. Specifics if possible. I am trying to explain it to some friends who are not quite as into science as I am. Thanks

Where are the roughest and stormiest seas in the world? i have been told off the SW coast of africa they are really bad, but i am not sure.

some people belive that the earth was created in 6 days others think it was a period of millions of years which is it what do you think:confused:

So we know that energy cannot be created only converted my question is does the same hold true for carbon, Is there alot of things in the same type of non creation only conversion cycle?

why is it said that gravity will only allow mountains to reach a certain height ?

As I recall parts of the North American continent have been 'rebounding' since the retreat of glaciers from the last ice age. As sea levels rise can we expect the ocean floor to sink due to the additional pressure caused by so much more water over it? If so would the sinking ocean floor in any meaningful way mitigate the risks due to rising sea levels? If the sea floor sinks would that result in any kind of corresponding lift of land not covered by ocean?

hi, can anyone give clear information on when will be snow fall and when will be rain fall? and why snow is salty and rain water is tasty? thanks, basha

(I put it here due to its connection with the seasons.) Okay, so, here's an article on British Double Summer Time. I read the article, and I read Wikipedia on it, and I still don't know what it is. What is it, how does it work, and why is it better? (...in simple monosyllables, please.) And is it equivalent to America's Daylight Savings Time, or does it go beyond DST? Is it the same as "Single/Double Summer Time? (Yes, Virginia, there is such a thing.)

After the devastating earthquake in Japan, a Sky report was issued yesterday, claiming the earth has tilted some 17 degrees on it's axis, consequently affecting the length of a day. If further quakes should occur of a similar magnitude, what then could this mean for the planet geographically and how will this affect climate worldwide? GF x

I know countries in the ring of fire experience the greatest number of earthquakes worldwide, but which of these within the ring fire experience the highest number of earthquakes? Does modern science know the numbers? Is there some sort of world ranking, for greatest number of earthquakes experienced (e.g. since 1900) out there for countries worldwide?

Dear Friend this is my page of the face book. you can find more about the petroleum Geology of MENA area and you are welcome to ask me any question regarding this subject and I will do my best to help. MEGF http://www.facebook....155520804506748

Topics to be discussed are the daily changes of the planet. Far North Pole shaken by moderate quake March 4, 2011 – NORTH POLE – A 4.8 earthquake rattles the far North Pole at a depth of 10 km at NORTH OF SEVERNAYA ZEMLYA (number 5 grid in Yellow) on the map of the Arctic Pole. The peculiar nature of the location of this quake leads us to conclude that since the magnetic north pole is now racing towards Russia and the Earth has been under constant bombardment from the rabid sheer of the solar winds over the last 48 hours, that this is a trembling effect in magnetic field generation- perhaps one more tangible sign that planet’s magnetic field dexterity is insidio…

Hello all, I'm attempting to decide what to major in out of my geology, environmental science, and physics & astronmy departments at my university. At the moment I'm thinking to double major but I'm unsure what combination would be the most beneficial for my future employment opportunities. I would like to study planetary compositions, atmospheres, and geological processes. I'm also interested in things such as stellar evolution and a general understanding of the universe which obviously leans towards the astronomy & physics department side. I'm thinking geology may be beneficial either way and that I need to make a decision on which of the other two I woul…

Recently i found one excellent blog, and most articles in it looks nice, so here i quote one from it and share it to all of us. Scientists found one largest planet at the edge of the solar system

Does anyone have any suggestions for good, versatile geological mapping freeware (or cheap software)? I am working on a project mapping heatflow data, so I need a program that has the capabilities of constructing structural contours for aquifers, isotherms, topography, etc. I am on a budget, so am not interested in any of the high-end programs.

If there is natural gas found say 20,000ft under ocean just below ocean floor, can we just drill a pipe and expect gas to come up due to immense pressure 20000ft below or do we have to put a pump to suck the gas out to ground level? also please suggest best way to do the same most efficiently and economically. Thank you

In my opinion we can help pollution in homes and facilities organizations from regulation by a governing body restricting the supply of oil. A national/regional broadcast system, Television and radio and internet that is making decisions about restrictions from weather patterns. If the weather is hot , oil should be restricted to preserve any potential waste. If weather is cold oil should be unrestricted. Incentives for homes , facilities and organizations to exchange appliances or get new appliances could be helpful. It would be a positive idea until Eco living is predominant. What do you think about that idea?

I read the infamous well in the gulf flowed with 6000 psi What causes such high pressure? Is the weight of the earth crust squeezing the petroleum filled pockets down, compressing it ?
