Hey guys, What do you think about iron fertilization? Find out about it on my blog: link removed

One of the Astronauts said theres a cloud covering the Earth. What did he mean by that? Was the Earth hard to see and why? Curious One

We know that moon is perfect in the 14th day of the month before that 13 days and after it 13 days be it 27 + the day in the month when the moon disappears so 28 days meaning the moon month is 28 days 28×12 = 336 : far away from the year we know So let's multiply it per 13! 28×13=364 days in the year which is admittable! Let's suppose months are based on the moon and year on the sun Hypothesis: Sun year = 364 days =13 months =52 weeks (exacly) Season = 91 days = 3 months and one week(exacly) Month=4 weeks (exacly) This is the true and simple and clear calculation of the year and we need to clean our messiness as humans life can't go on if we base it on wrongnes…

Sorry if this is a stupid question but it's outside my field and just something I was curious about... As we burn fossil fuel we release Co2 "into the atmosphere" So my question is - does this Co2 collect in a band around the planet at a particular altitude or is it dispersed at all levels throughout the atmosphere?

OK let's try it this way: Does anyone have a graph showing the average global accumulation of CO2 against altitude. One 2 axis graph (altitude and %concentration) - no names of height - nothing else. Also does anone have a map showing a plan view of the globe with CO2 density clearly indicated over identifiable locations. Nothing else. No opinions. Just one graph and one map both from identifiable and generally considered reliable sources. If either doesn't exist please just say so and I'll stop asking. And please refrain from polluting the thread.

This one has bugged me for years but I never asked before; I noticed the water freezing on a small lake from the leeward side over towards the wind exposed side. What is responsible for the rippling water freezing last?

considering the earth is nearly five billion years old and totally empty of any living thing then what was going on in all those billions of years before life did emerge.

I have just been listening to a programme about burying carbon in the american Midwest or central China. Why not the bottom of the sea? This is, after all, where Nature buries it. We have the International Space Station, and projected missions to Mars, but ocean bottom stations are still only available in Hollywood Scifi movies. I have spent the last half century hearing about how much treasure is to be had at the bottom of the sea, yet we know proportionately more about the Solar system than the depths because we put proportionately more effort into space research than subsea research. Why is theis? Surely the payback would be greater for many cen…

A friend sent me a you tube video titled " 200 proofs that the world is not a spinning ball" Some of the guy's science seemed crackpot but there were a few points that really got me thinking. Discussion with friends and family haven't managed to solve any arguments. I hope you sceince lovers can help me put some questions to bed; 1, Railways, roads, pipelines and bridges are all made perfectly flat/level. If the earth is spherical, they would have to allow a curvature of 8 inch per mile. 2, If you fire a cannon perfectly plumb without any wind, the ball will land back to earth close to the cannon. How could this be if the earth is spinning at 9Mps? 3, If an…

Hi there all, I'm a student in Molecular Biology with an interest in Biochemistry and this is what I'm going to specialize in the future.I am currently doing a coursework (a review article) in one of my favourite research fields in science - the origin of life and the evolution of metabolism so you are probably already guessing why I am writing in the Earth Science section.I am slightly lost among all those papers regarding the early conditions of our planet and It's hard for me to form an opinion.And this is very important since I have to be able to discuss the process of abiogenesis with respect to these conditions.So I need some help from a person with a good backgroun…

Hi, You know in like 7 billion years the sun will come in contact with the earth, red giant... So maybe the ecosystem/earth NEEDS HUMANS help.. Maybe, when we have the tech, we would bring nature to another planet?... We humans have gone out into space. nature has not gone out into space. think of it, how would nature (trees,grass,rivers,etc) move to another planet after the earth burns for infinite? of course, humans are also destroying the earth, but people are starting to get Eco friendly,etc.. what do you think? is this complete nonsense or maybe a possibility? because how would nature/ecosystem get from earth to another planet? it would all get burne…

I am just not quite sure what makes sedimentary red sand stick together? Or any other particles in the geological column. Is it pressure, time , heat , dehydration , or just the particles being held next to one another for so long a time period ( like 10's or 100's of millions of years) that the particles develop some form of atomic bonding , from a sheer , proximity perspective? The end result is they ( the particles en mass ) become a rock in the process ! How ? By what mechanism are they held together ? Mike

Link removed I wrote this based on some googling and wikipedia, i hope you like it, give your opinion about it and tell me if there is anything wrong with it and what improvement should i do.

I have been looking for a website to know young earth theory. Finally i found this. I think it is more informative to us to know about the history of earth. Every science student should know about the histrory hidden behind our Earth. It is full of scientific information that can increse our knowledge.

Out of 39 of the major earthquakes around the world, 35 of them occured in Winter, Fall, and early spring, with the remaining 4 (four) occuring in Summer (June,July,August). So the question is, are the movement of plate tectonics actually either the contraction or expansion of the whole of the planet, in direct correlation to it's position to the Sun?. Winter, fall and spring are the closest earth comes to the sun, within our calendar year. Is this a expansion period?, thereby giving plate tectonics movements validity, as a cause of earthquakes?. Perhaps expansion of the planet as a whole, in relation to it's distance to the Sun, is the real culprit. Wheras in the Summe…

Some sites suggest the height could have been 4-5km. I want to confirm that this is the initial splash height? And what was the height that would reach land several 100km's away? Some sources say the weater depth of impact was only a few hundred metres deep, would this mean the wave would have been not very high when it gets to a distant coast? Would the height and amount of coastal inidating be alot worse if the impact was in deep ocean rather than shallow sea? Finally, if the comet hit in deep ocean would that redcuce the amount of damage it did to the the whole world & life? thanks

Evolution of Himalayas and Tibet, and the Great Volcano Here's an article on Evolution of Himalayas and Tibet and formation of the existing continental plates, which proposes some major twist in the existing theories regarding Plate Techtonics. It needs to be submitted before reputed Organizations or Scientists for open discussion, further exploration, approval and acceptance. The essence of the proposal can be quoted as "Himalayas and Tibetan Plateau was not formed due to the collision of the said plates but due to a huge and massive volcanic eruption and the entire Tibetan plateau is the huge Volcanic Crater formed due to the eruption. The Volcano was so massive that…

I live in the Great Lakes region of the US, and my area always gets hit hard with snow every year, predominantly via lake effect...If Lake Erie for example remains somewhat warm in the early parts of winter, the cold air from Canada passes over, gets "heated" and rises, gaining moisture, and freezes..or whatever (I'm not into the lingo). Here's what I don't understand. If the world is heating up due to global warming, and the lake stays warm during winter, should we have less chance of snow. Even though the warm air rises and takes on moisture, shouldn't there be less occurence of snow b/c of higher temperatures via global warming? ~EE

I am currently reading this fascinating book about the effect on sea levels the last time the icecaps melted about 15000 years ago. It was written by a Californian sailor and discusses now submerged places such as Doggerland in the North Sea and others around the globe in the light of the effect on human history as well as changing landforms and coastlines. Doggerland is interesting because the oil companies have released much North Sea survey data for study by anthropologists, and other scientists. No outlandish claims are made and the book has lots of solid references to modern research results. Below is an extracted map of Doggerland. The main point se…

I hope this is the right section. So I'm working on a science fiction story where people crash land on an alien planet. The first thing they need is a heat source but none of the plants on that planet are flammable. I thought it would be cool if they found a type of rock that gets really hot if you strike it with something hard. Is such a material scientifically feasible? If so how could I explain that in science terms? Can anyone come up with a better heat source?

Hypothetically speaking, (meaning, please don't lecture about practical constraints ) What if, instead of releasing green house gases directly into the atmosphere we can pump them to the ocean floor and release them there? Will the green house gases dissolve completely as they rise through the water, or will they eventually reach the atmosphere, making the whole process useless? What are the implications of such a process? Can dissolving these gasses in the oceans instead of releasing them into the atmosphere reduce the damage to environment, ecology and the amount of heat gain? Or will it only produce far worse results? What if the process can be carried out wi…

About 10 years ago I went to Sicily and during my stay there I explored a limestone canyon (not sure what it would be classified as). I had a great time exploring small caves and used chisels and brushes to excavate some small fossils. This was not a heavily developed area, virtually no tourists, and the site was on private property (I was given permission by the property owner). While searching for fossils, I found (what appears to be) a vase handle and have kept it ever since. My question is...how old is it? I'm not trying to scam anyone or anything but, should this be in a museum? Is it too "young" to carbon date? Is it likely just a piece of trash from 20 y…

Have you ever thought why moon doesn't fall down on earth? well here's your answer. Do give your feedback. video deleted Content of the video: Before answering this question let us understand what force is? What do forces do to an object? In short, you can say that forces change the motion of the object. Have a look at three different cases for force. Suppose an object is moving to the left and we apply a force in the same direction, in this case the object will speed up, if we apply force in the opposite direction to the velocity of object, the object will slow down. Take a case when the force is applied perpendicular to the velocity of the object. Let us…
