Why does graviety allow a gap between a rocky surface and the atmosphere, the sky? And what is the difference?

Question

between an atmosphere and a gas planet?

Answer 1

There is no space between. You think that the earth is the center of it all and look from that point of view like the sky/atmosphere is in the earth. It is the earth that is in the atmosphere. Science tells us that in every solid thing there are atoms, subatomic atoms etc and in the end it all boils down to energy/space/nothingness. Within that nothin is everything. and vice versa. which came first the chicken or the egg. Theyre both part of the same thing and are bothe energy. The egg is an effect of the chicken and the chicken is an effect of the egg. They are the same but expressed differently. So when someone says which came first the chicken or the egg. Tell em they are the same thing expressed differently.

Answer 2

It's not as though there is some structure up there that's called the sky. The atmosphere begins exactly where the solid or liquid surface ends and there is no gap. The atmosphere itself peters out as you go up, becoming rarer and rarer until it merges with the vacuum of interplanetary space.

A gas planet (e.g., Jupiter) has little or no solid surface. So as you go down, the atmosphere just gets denser and denser. If the temperature is above the critical point, there may be no liquefaction, and the gas just keeps getting denser as you go down.

Answer 3

What kind of a GAP are referring to??  Where is this occuring??  What is the reason you even ask this??

PLEASE: Try re-wording that question so it makes sense to us.  

Or are you just having fun with us??

Answer 4

There is no gap between the earth and sky. If there were, you wouldn't be able to breathe! The sky rests right on top of the ground.

Every material has a density. Gravity pulls on denser materials harder- that's why a metal pipe weighs more than a tube of bubble wrap, and why the bubble wrap floats in water and the pipe doesn't (The pipe is denser than the water, and the bubble wrap is less dense). Any planet's center of gravity is at or near its center, and so for the most part the denser things are going to be closer to it. Of the main things our earth has, the densest is heavy metals like iron (found mostly in the core). Next is solid rock, forming the crust of our earth. It floats on the mantle, the name for that iron and melted rock inside our planet. The final main part of our planet is the gases, like oxygen and nitrogen. They are the lightest, and so "float" on the top of the rock.

You can see this yourself with an experiment. Find a tall glass and fill about a third of it with cooking oil. Now add about the same amount of water. Now dump a handful of dirt in there too. Stir it all up, then let it sit completely still for a while. You will see the oil floats on top of the water, and the water "floats" on top of the dirt. In fact, the air also "floats" on top of the oil too!
