the waves have energy that makes them rise and fall from the wind is that all there is to it?????

Can anyone correct me if the following statement is wrong: I assume there we cannot conduct a conventional experiment to prove plate tetronics. The proof lies in the following: The theory fits observed data The theory predicts which prove true when we check them

Can someone please explain in simple language and in step by step terms how to tackle a problem like this? I have to answer a question that is very similar to this. (Only the numbers have been changed). But I haven't got a clue where to start. At a guess my instinct is to find a way to convert these numbers into the same or similar units? I have of course used different numbers here and I am not trying to cheat or anything (it's just a practice question anyway), as I really would like to understand how to do this. But my maths isn't strong (I'm an adult learner BTW), so I would appreciate as simple and clear a breakdown of this problem as possible. …

Hello, has the iron we mine now come from meteorites ??

I came across an article of a doomsday theory regarding the BP oil spill: http://www.helium.com/items/1882339-doomsday-how-bp-gulf-disaster-may-have-triggered-a-world-killing-event Of course, this article may not be entirely true as it is very far fetched in nature, but it made me wonder how the BP's operations have affected the general population around the world. For instance, what did the event cost us financially and environmentally? How do these events relate to the everyday person? How did this affect our future?

I have come across the following paragraph on drilling of oil wells in a book: Natural gas is found above petroleum, trapped between the rock cap and the petroleum layer. With the help of giant rigs, a hole is drilled in the earth's crust. When the hole reaches the rock cap, the natural gas comes out first with a great pressure. After that, petroleum starts flowing out due to the pressure of natural gas. When the pressure falls further, the petroleum is pumped out by electric motors. What does the line petroleum starts flowing out due to the pressure of natural gas mean here? After the natural gas comes out with great pressure, petroleum beneath the natural gas fl…

I have had this rock since I was a kid. Does anyone know what it is?

hello I was reading this book The earth , its birth and growth but it is on google books and not complete it talked about theories of earth's core http://books.google.com/books?id=Bw84AAAAIAAJ&pg=PA28&dq=how+was+the+core+of+the+earth+formed+%3F&hl=en&ei=Mn89TKmIIYWd4Qa7mc3GAg&sa=X&oi=book_result&ct=result&resnum=7&ved=0CEIQ6AEwBg#v=onepage&q=how%20was%20the%20core%20of%20the%20earth%20formed%20%3F&f=false from page 28 to 31 and then 32 and 33 are not there I want to know is the idea that "the components of earths core were molten and then iron and heavy metals went to the centre and the li…

I'm looking to purchase a polarizing microscope on a small budget, and I've realistically narrowed my options to the two little-known (and probably Chinese made) brands of Variscope and Amscope. There is a helpful discussion on Amscope in microbiology and immunology forum in this webpage, but nobody has mentioned variscope yet. Does anyone here have (or know someone who has) experience using or owning a Variscope? Are they any good? I'm a bit weary because as the old saying goes, "if it sounds too good to be true ir probably isn't." But, unless anyone here knows where I can find a functional binocular or trinocular polarizing scope with an analyzer/rotating stage…

A recent true story. On a warm, humid summer day, I walked into an air conditioned store and stayed for several minutes. I assume my eyeglass lens temp stabilized at the temp of the store's A/C'd air. As I left the store, my glasses "fogged up" until the outside air warmed them a bit. I went home, looked up the weather on the Internet and found that the outside temp was 82° and the dewpoint was 73°. Should I interpret my experience to mean that the A/C'd air in the store was at or below 73°?

Hello to everyone reading this post I have a very simple question about gravity. We have seen planes flying at altitudes of around 35,000 ft. So if a plane takes of from Hongkong it will land in spain more quickly. And it will take more time if it travels form spain to hongkong. This is bcoz of the rotation of the earth from east to west. SO My question is if i happen to lift myself up in space by about say 2ft, will the earth pass by and say within a few hours spain will arrive automatically due to the rotation of the earth form east to west . And then i can land on the earth. so why use planes in a east to west travel..... or is there anything else.

First of all, I can't imagine why it took so long to develop a solution which appears to be so absolutely effective. Not knowing the details of how a blowout preventer is designed, most could only guess in the dark about how a potential solution would develop, not knowing that pieces of it at the outlet were removable. Just have a hard time understanding why so much time and resources were wasted and why so much oil flowed out while they used such ineffective ideas when such brilliance was there all along. Surely, there are plenty of factors that I would have no idea about. I have read about how the Ixtoc slick, slightly bigger?, the gulf recovered from in only 2…

The Quran on Seas and Rivers: Modern Science has discovered that in the places where two different seas meet, there is a barrier between them. This barrier divides the two seas so that each sea has its own temperature, salinity, and density.1 For example, Mediterranean sea water is warm, saline, and less dense, compared to Atlantic ocean water. When Mediterranean sea water enters the Atlantic over the Gibraltar sill, it moves several hundred kilometers into the Atlantic at a depth of about 1000 meters with its own warm, saline, and less dense characteristics. The Mediterranean water stabilizes at this depth2 (see figure 13). Figure 13: The Mediterran…

Hello, I am looking to do an experiment and I need a pound or so of Marcellus Shale with the proper Space Group. If possible, I would like to know the mean density and types of gases. Can anyone send me in the right direction? Thanks, Matthew

hi every one I saw this and was very impressed Tell me what you think http://www.harunyahya.tv/videoDetail/Lang/4/Product/1251/THE_CREATION_OF_THE_UNIVERSE http://www.miraclesofthequran.com/scientific_index.html

Hey all, new member here with his first topic. I saw this one article on the Web that made me a tad concerned. http://newsfeed.time.com/2010/07/12/doomsday-could-bp-spill-kill-all-life-on-earth/ Is there any validity to that? Theres also another article within that, which debunks the theory. Theres a link to it in the article posted above but I can post it here if you can find it. Cheers. -Navalius

I just read an article in New Scientist and there is mention of :...the advent of plate tectonics that help regulate carbon dioxide. Could someone please explain how this correlation comes about? It doesn't make sense to me!

First of all I would just like to say thank you to those reading this and those who help me understand more, please bear with me whilst I tell you about my day My Wife and I was lying on the lawn enjoying the days sunshine, during that time I got up, placed the news paper on top of the wall (4ft) then returned to where we were lying and said to my wife that the newspaper was getting more sunshine than us as it was nearer to the sun, she laughed, I laughed, then it got me thinking more in depth as I looked at the different height of the surrounding trees and shrubs and started thinking some more:D I have googled LOL and the popular answer is that on a sunny day th…

Hello I have an important question. When did human understand(find) that different colors are avoided from water in different depths? I don't want to know the exact time , only say it's century plz. And please tell me the source of your text. thank you

would it be possible to use a freeze drying process to separate crude oil from sea water?

I think armageddon is real and at the same time i dont think it is real. If you are reading this and have no clue what armageddon is, it is supposed to be the end of the world. If you think its true or if you dont you can reply and tell me your opinion. That would be really great y'all.

I haven't really seen a thread specific to this yet, but I've been reading a lot of speculation about the Icelandic volcano Eyjafjallajökull which recently erupted and severely disrupted European air travel. http://en.wikipedia.org/wiki/2010_eruptions_of_Eyjafjallaj%C3%B6kull Specifically, I've read that Eyjafjallajökull sits next to a larger volcano named Katla, that has always erupted after Eyjafjallajökull erupted. If so, this could mean prolonged disruptions to European air travel. Oh yeah, by the way... here's a photo:

Starting this month I will be doing monthly analyses on seismic activity and solar activity. It is up to others to determine if solar activity is causation of seismic activity or coincidence. Just remember energy is neither created nor destroyed but it is simply converted from one form to another. My goal is to have seismic activity divided by each tectonic plate, however I am only one person and it's to much work to do all by myself. If anyone wants to contribute to this research, go on ahead.

So, i was thinking about the oil spill they've got offsore on the states and i started thinking: Surely its possible for an oil resovoir to spring a leak under natural circumstances. for instance, a fault line, erosion(not to sure how much of an effect this has on the sea floor). Okay, I'll admit i'm not to sure on the mechanism, but I do know that oilwells can experience geological activity and there are a couple of exploited resovoirs which are on fault lines. So, are there any known natural oil spills? As in not a direct or indirect result of human activity. no pipes drilling or tanks involved.
