Slim Posted January 14, 2009 Share Posted January 14, 2009 The one on the left, the water one ? doesnt look correct, way too small surley ? ( and dont call me s(u)irley!) That's the point of the imagery, theres far less water and air than you might think, very thin layer relative to the size of the planet. Link to comment Share on other sites More sharing options...
Sebrof Posted January 14, 2009 Share Posted January 14, 2009 This interesting image shows all the air and all the water in the world, if gathered into a globe, to scale with the planet itself: Rubbish. S Link to comment Share on other sites More sharing options...
Chinahand Posted January 14, 2009 Share Posted January 14, 2009 Where did you find the image Slim? It won the best science illustration a couple of years back - I saw it in the print edition of Scientific American and spent an age to no avail trying to find it on the internet. As it won a science illustration price I presume its accurate! Its worth trying to do the calculation! Try having a go Sebrof - it should take about 20 mins on google I reckon!

Chinahand Posted January 14, 2009 Share Posted January 14, 2009 He he Volume of water = 1,386,000 billion cubic km. Volume of a sphere = 4/3 x pi x r^3 Therefore volume of earths oceans can fit in a sphere of radius = 691 km. Radius of the earth = 6378 km. IE the earth has a diameter over 9 times the volume of its water! Link to comment Share on other sites More sharing options...
Chinahand Posted January 14, 2009 Share Posted January 14, 2009 One thing I've just realized - the picture is wrong!! It shows the ice cap still on greenland - but has used the total amount of water including snow and ice in its calculation! Link! Link to comment Share on other sites More sharing options...
