Gravity and pressure both do lots of things. In the center of a star (such as our sun, Sol) it is the gravitational force of the star's mass which holds it together as a star, rather than an expanding cloud of gas which it otherwise would be, and which also causes the high pressure that exists in the center of the star. Stars are composed of a substance known as plasma, which is a super heated gas in which all the electrons are ionized rather than being bound to atomic nuclei. It is the weight of all this plasma which presses down on the center of the star causing the extremely high pressure and temperature which allows nuclear reactions to take place. Only when atomic nuclei are under enormous pressure will they ever get close enough to undergo nuclear reactions, and that is because they are all positively charged, and therefore repel each other. So gravity and pressure, working together, make it possible for the sun and stars to shine. Without gravity and pressure the universe would be a dark, cold place.
Head pressure=specific gravity*1000*gravity*height. Therefore if specific gravity is increased head pressure will increase.
Neptune's "surface gravity" is a bit more than Earth's, but Neptune's gravity would not crush you. If you went deep inside Neptune the pressure would probably crush you. That's not gravity crushing you directly, but the pressure. This pressure is caused by the combination of gravity and the planet's resistance to being compressed by gravity. The pressure increases rapidly with depth.
I think it can because there is a lot of atmospheric pressure so it can be crushed at one point.It would be crushed very quickly. The pressure on Venus is almost 100 times the pressure on earth. The gravity on Venus is less than the gravity on earth, however.
Air pressure is a product of the operation of gravity on the mass of atmospheric air. If there were insufficient or no gravity on Earth, the atmosphere would drift off into space. There would be no air pressure. But, because there IS gravity on Earth, the atmosphere presses down on Earth's surface, resulting in the phenomenon known as air pressure.
No
Head pressure=specific gravity*1000*gravity*height. Therefore if specific gravity is increased head pressure will increase.
Gravity is a function of mass and distance. So, no air pressure does not affect gravity.
It is gravity.

The way gravity effect erosion is that the pressure of gravity pushes on the landfill

There cannot be buoyancy without gravity because without gravity there will be no pressure.
There is indeed a relationship between gravity and atmospheric pressure. Gravity attracts matter with mass, in this case gas. The atmosphere being a layer of gas, the stronger the gravity, the higher it's pressure. I if you seal gas in a tank, and increase its mass (by adding more gas) the pressure will increase. Now imagine that the tank is the earth, and gravity is exerting a down force on the gas... It's like water. Although it can't be compressed, water exerts pressure because of gravity; the deeper you go the higher the pressure. Now imagine the atmosphere pressure on Jupiter....

The pressure of gravity on a surface is(total force of gravity on the surface) divided by (area of the surface)
