made me smile | and think | all earth’s water in one place

this made me smile this morning. how odd is it?

if we think at our planet, we see it mainly covered with water, therefore we think there is a huge amount of water in it. the actual figure is that there is in fact very little water on earth if we compare it to the size of the planet as a whole.

usgs has created the above image to give the idea. it is a 3-dimensional ball shape [so much bigger than it appears on screen] and has a diameter of about 860 miles [that is 1384 km]. therefore it is a Lot of water, but really tiny if compared to the actual size of planet earth.

about 70 percent of the earth’s surface is covered with water; oceans alone hold about 96.5 percent of all water. therefore this 96% is composed by saline water. moreover, most of the remaining fresh water is locked up in ice at the poles or is underground were we can’t reach it.
