    Just interested to see what people say really, these are just three things I've been thinking about lately:

    1) What stops Britain getting really cold in the winter?

    2) What do we learn from the fact that the Earth is round?

    3) Why are the Himalayas higher than the Alps?

    1) the North Atlantic Current
    2)please specify
    3)more energy when the continental plates where colliding? or perhapse the himalayers have been going up longer


    Come see some of my art work at http://nevyn-pendragon.deviantart.com/

    Feel free to elaborate, how does this work?

    Ummm, in other words, why is the earth round?

    Perhaps (although you might want to back that up if you can find the numbers), this is probably the hardest of the questions of the lot.

    1: The Gulf stream is a warm [surface] Atlantic current which flows north easterly from around the Caribean sea area and wraps around Britian, it is a surface current, the winds across the UK mostly blow from a south westerly direction and are warmed by this current, when the wind blows from the east however it gets gets bloody cold here - ice cold wind from Siberia.

    Beneath the gulf stream and flowing in the opposite direction is a cold current from the arctic, as it gets to warmer latitudes it rises and warms and then flow north.

    2: You can never fall off the edge, and the sun does not fall into the sea.

    3: becuase the forces causing the plates to buckle are greater it is also the joint of two plates moving faster - that's my understanding BUT I'm not an expert so scheck this last answer out...

    That it's round.

    3) Why are the Himalayas higher than the Alps?
    Because they smoked more dope.

    The earth is round, like other planets because of gravity, it pulls everything towards the center of mass.

    It would be more spherical, however, if it was not spinning, because that creates a bulge at the equator from centripetal force.

    1) Any idea how much heat is exchanged between the atmosphere and the ocean of the South-Western coast of Great Britain? You might be surprised to learn that it is about 0 K; it is a popularized myth that the North Atlantic Drift keeps Britain warm in the winter. Anybody else..?

    2) Yes, but I'm really looking for physical reasoning as to why its round.. perhaps the question wasn't made clearly enough.

    3) It's certainly a possibility, as I noted earlier nobody has the definitive answer. Another possibility is that the Himalaya are at a different stage in an orogenic cycle. There are actually cycles where the topography rises until the strength of the rocks can no longer sustain the mass of the mountain, then the mountains will spread its mass so it shrinks down and gets fatter. SO perhaps the Himalaya are pretty near maximum height and the Alps are near a trough in the cycle?

    If you don't believe me that mountains will have a maximum size (determined by rock rheology), then why are mountains so much larger on a planet like Venus? Because Venus doesn't have any water in the ground so the rocks are stronger, on Earth water drastically weakens the rocks.

    Correct, gravity is the dominant force! But only half the answer.

    What must be true about the material that the earth is made of for it to acquire a spherical shape (under self-gravitational attraction)?

    Ha ha, you've certainly lost your serious bone since I was last around, no longer do you sign your threads

    Posting two in a row is frowned upon, 3 is even worse, please edit them down to one and then I'll delete the other two

    Billiards,

    You are right, I just checked up and it's a mixture of all those old leaky nuclear reactors we have and hot air from politicians that keep us warm in winter.

    Sorry.

    I had no idea that all the geography, oceanography, climatology and meterology people wree wrong.

    Ha, well


    I found this to prove my point, people have known about this since the 70s, but the misconception that the Gulf Stream keeps us warm has spread like wildfire regardless.

    You wanna know what really keeps us warm? Well, unfortunately I couldn't find a graph to illustrate, but it's basically the biggest radiator in the world, a big chunk of ocean in the NW Pacific. It just so happens that there is a large planetary wave in the atmosphere which transports heat from the radiator to Britain. The wave is not free to move because it is pinned in place by the Rocky mountains, neat huh?

    Billiards,

    I hate to say this but you have misinterpreted it, now please provide a link to it so I can read all about it..
    Like compare it with this...

    Oh right, sorry megabrain, i didn't realize you were so enlightened. I googled for a source to back me up, and I couldn't find one (I didn't learn about this on the internet - it was a gem of knowledge passed on to me by a professor at my uni). But then, as I had almost given up, I stumbled across this:

    It wouldn't be the first time an independant scientist has overturned some theory, so let's say whereas I was convinced, I'll keep an eye open for confirmation.. Thnx for the article.

    so if more water melts into the ocean, there is going to be less heat travellinbg north?
