Luckily, science doesn't require belief. All you have to do is gather up some commonly available facts and perform the calculations yourself.

That's a good response to that attitude. But I've talked with those, when you suggest they look it up if they don't believe it, who say "I'm not going to do that!" Their mentality is apparently that belief trumps the facts. It's the same rationality level as the global warming deniers.

I have never seen this image before. It's fascinating, as are the others posted here. Thanks.

No, I've never seen it (though I've seen a few similar images that used shapes other than spheres to illustrate the idea.

I'm the author of a very similar image, which won a 'Visions of Science' award in 2003. I made three versions because having direct experience of the areas depicted (e.g. knowing what it's like to drive from Northern France to Southern Italy) helps with the sense of scale.

I also made a version which shows the volume of whole atmosphere at sea-level density:

There's 5,140 trillion tonnes of air in the atmosphere, but most of it is very close to the surface. At 5.6 km above the ground (about half the height of an airliner) half of the atmosphere is beneath you.

I call this type of image 'concrete visualisation', a term I have tried to explain here: http://adamnieman.posterous.com/what-is ... ualisation

Concrete visualisation can work well in astronomy. In this example I have tried to get a feel for the surface area of the Moon by mapping a familiar area onto it. You can see the relative sizes of the Earth and the Moon in the image on the right.

I'd be delighted if APOD wanted to feature one of my 'All the air' images, or the surface area of the Moon image. What do you say?

I find XKCD's Lakes and Oceans is good for understanding the depth of something like Mariana Trench because it shows both the standard depth graph as well as an accurate horizontal scale inset. It's also very interesting for a number of other reasons!

Same infographic, different picture. It was in a french magazine "Science & vie" and the meaning was the same.

I saw it many months ago. The oceans (mass 1.430E21 kg) fill a ball of 698.901 km radius, adding water (clouds and vapour) in atmosphere makes it 698.022 km, and adding icecaps, groundwater, lakes, rivers, makes it 705.022 km radius. (Data from from "Patient Earth", John Harte and Robert H Socolow, 1971, Holt Rinehart and Winston Inc.
The dry atmosphere (mass 5.12E18 kg) would take up 981.433 km sphere if at atmospheric pressure.

i hadn't seen it before , I love it , I'd also like to see the atmosphere one as well , please post a link .
I found a link after some googline: http://www.sciencephoto.com/images/imag ... =690550330

Dude , that is so cool , thank you .

This morning on the Weather Channel during their silly WUWA (Wake Up With Al) show.
By the way, I don't believe it. There doesn't appear to be enough matter there to even "paint" the oceans back in place.

I saw it at Phil Plait's talk in Boulder, CO on May 12, 2012.

First saw this last week on USGS website (linked from their facebook page): http://ga.water.usgs.gov/edu/earthhowmuch.html USGS credits Jack Cook of the Woods Hole Oceanographic Institution same as APOD.

Saw it first on the Earth Science picture of the day facebook page

haha, this, I too saw it first on there around a week ago.

Similar version seen last week for the first time in a presentation by Mark Schrader of the Ocean Watch organization.

I've not seen this exact image, but here is a similar one (nicer too, IMHO, although the ocean floor is less well shown):

This, then, is a picture of God: Since that small blue marble is what creates life on this planet.

Can someone post a link with this picture with atmosphere

I've never seen these pictures before

Saw it the day before on Gizmodo Australia.
Replete with all the dumb comments that their comment fields attract.
Much better pic here though
