An artesian well is a pumpless water source that utilizes pipes that are underground to allow water that is under pressure to rise to the surface for use. One needs to use porous stone sandwiched between two layers of a substance such as shale, that is impermeable.
Artesian wells formed when pressure is great enough to push any water to the surface.
The term artesian means that the water is contained in an underground aquifer and/or reservoir. The fact that it is spouting means that it has artesian pressure and is a flowingartesian well. The geology of the site determines the amount of pressure on the reservoir and not all artesian wells have enough, or any pressure to spout. The pressure comes from the weight of ground structures and ground water pressing on and around the underground reservoir.
The moons mass in general causes the tides. Mass has gravity, and the moon is massive enough for its gravity to pull noticeably on the oceans.
No, a planet does not collapse because gravity isn't strong enough to provide enough pressure to crush a planet. You might make a planet heavier and heavier as to increase its gravity but at some point the pressure in the planet's core will be high enough to support nuclear fusion and the planet will have changed into a star. At that point radiative pressure also begins to fight gravity.
This type of well is called an Artesian Well. If the pressure is great enough to raise the water above the ground level, it is called a Flowing Artesian Well.
All matter has mass. gravity is the attraction of objects with mass. The mass of the earth is high enough that gravity from the earth pulls the air towards itself.
I think you refer to an Artesian well.
When enough hydrogen gas collects in a region of space, the collective gravity of the gas begins to pull all the hydrogen atoms together. Eventually, when enough hydrogen has fallen together, it heats up and compresses the gas. If there's enough gas, it will collapse under gravity until the internal temperature and pressure are very high, and hydrogen fusion begins. And a star is born. It's not all that unusual; there are perhaps a trillion stars in the Milky Way, and hundreds of billions of other galaxies in the universe.
The moon does not Cause tides. How can the moon cause tides when it does not have gravity strong enough to create it's own atmosphere.In this case how can its gravitational pull cause tides on earth,which at distance from the moon
