    Well I should say smooth... there are no such a thing as "high" mountains or peaks,

    no matter how high you climb, (less than 10000 meters or about less than 6 miles) , you wont see anything 200 miles away,... horizon..

    So the Everest "peak", less than 6 miles tall, on "top" of the Earth (40000 miles circumference) should look similar to a

    grain of salt less than 200 micrometers tall (if you can SEE it) on top of a basketball. (30 inch circumference)

    Did i do the calculation right? or is it too late and need a drink?

    BTW, You can guess what my next topic is going to be....

    What is more, the atmosphere is only 20 miles thick and the air up the top is very thin. Compared to how big the earth is, that is a very very thin layer. Not much for us to completely pollute either.

    I thought I would check my figures and "our" bit of the atmosphere is only 10 miles thick and as you know - you can barely breath on Everest.

    The structure of the atmosphere

    The atmosphere is made up of several layers: the troposphere, stratosphere, mesosphere, ionosphere, and exosphere. Closest to Earth is the troposphere. Most of the clouds you see in the sky are found in the troposphere, and this is the layer of the atmosphere we associate with weather. Extending up to 10 miles above Earth's surface, the troposphere contains a variety of gases: water vapor, carbon dioxide, methane, nitrous oxide, and others. These gases help retain heat, a portion of which is then radiated back to warm the surface of Earth.

    Above the troposphere is the stratosphere, which includes the ozone layer. The stratosphere extends from about 10 to 30 miles above the surface of Earth. Ozone molecules, which are concentrated in this layer, absorb ultraviolet radiation from the Sun and protect us from its harmful effects.

    Thirty to 50 miles above the surface is the mesosphere, the coldest part of the atmosphere. Above the mesosphere, in a layer called the ionosphere (also called the thermosphere), things start to heat up. Temperatures in the ionosphere, which extends about 50 to 180 miles from the surface of Earth, can reach up to several thousand degrees Fahrenheit. Beyond the ionosphere is the exosphere, which extends to roughly 500 miles above the surface of Earth. This is the outermost layer of the atmosphere, the transition zone into space.

    you can barely breath on Everest

    It is getting better at sea level after they implemented a few environmental laws, but i will probably start another topic once i get validated on the numbers i just presented,

    it may be 100 micrometers instead of 200, even 200 is good eunogh for the next question, probably in another topic..

    The world has no more than an 'onion skin' of breathable air surrounding it.

    what the flood has to do with this topic?

  • stillajwexelder

    Yes even from an airplane flying at 40000 feet you can not see as much as you think - actually the math is very easy to do - simple geometry
