Earth has a suprisingly small amount of water compared to other Solar System bodies

When you consider the amount of ice.
Even Pluto has more

It’s because we drink it all, dumbass

Where does it go after you drink it?

i don't get it. some of these planets are just floating balls of ice?

Yes.

that's dumb.I need volume of liquid water for better comparisons.

Europa might even have more liquid water than earth does if scientists are right about the ocean under the icy surface.

that's all a bunch of horse shite.
We have no idea how much water ice is on pluto. It's theoretical. the surface is covered in ice alright, compromised of 98% nitrogen. They theorize it's water ice underneath that.
Europa is covered in water ice on the surface, and we think, key word think, or theorize, that underneath that layer of ice is an ocean of water.
The chart you posted is all theoretical.

Water is one of the essential components for life, as we understand it on Earth.
Think about the shear amount of H2O just in our solar system.
Then extrapolate that across the galaxy and universe. That's a lot of water, and a lot of potential life.

There's a substantial amount of data to make the theory pretty strong.

Yeah but our water is liquidy and awesome. Try swimming on Callisto, dumbass.

This.
Yes, it’s a theory, but given the types of fractures on the (relatively young) surface, the trace amounts of clays and salts on the surface, and it’s proximity to Jupiter which is likely causing heat-generating tidal flexing, Europa sounds like as strong a candidate as any for extraterrestrial life.

I did not know that.

Maybe, but they have no idea how thick it is. It could be 10 miles deep, or 100 miles deep.
All they know is that plumes of some substance have jetted out from the surface of Europa at certain specific times and those plumes contain Hydrogen and Oxygen, which they assume is likely to be water vapor, hence, there must be an ocean of water under the ice.

They know a little more than that:

”We're almost certain one is there," she told Space.com. "One clue was the mass of Europa. Combined with when we measure the density, we get a figure close to one [gram per cubic centimeter] and water is the only material like

The way we know some is liquid was [the probe's] magnetometer," Phillips said. "As [Europa] goes through Jupiter's field the magnetometer saw deflection exactly where you would expect if there were an induced field."
The only way to get such an induced field is if there's some substance that is globally connected, and conductive — and only salty water fits the bill. Phillips noted you wouldn't get the same readings with isolated pools of water, like what's found under ice sheets on Earth. Slushy water-ice mixtures don't work, either. "Maybe graphite could get you that, but that would be ridiculous." she said, given what scientists know about how planets formed in that part of the solar system.
quote:
Phillips noted that given the rate of cratering on all the surrounding moons, Europa's surface doesn't look like it is more than 50 million years old. That means there is some way the planet is getting resurfaced relatively often. If the moon were covered with ice and had only a rock layer underneath it, you'd expect a much older-appearing surface.
Obviously not direct evidence, but that’s quite a bit of circumstantial evidence.

Europe is on earth dumbass

Too bad we'll never know for sure because it would be our asses if we ever attempted any landing there.

The list goes on and on of all the necessary requirements that, so far, only the Earth is known to have present all at the same time.
