cooler particles are slower moving thus more dense. the more dense the material the further it will sink

How do planets float in space without any gravity?
They do not "float". The planets are in motion, and that motion is governed by the gravitational pull of the Sun (and, to a lesser extent, that of the other planets). The position of the planets and their respective velocities is such that there is a balance which keeps the planets in their orbits, as opposed to either flying out into space or being pulled into the Sun.
Which force pulls everything down to earth?
The force that pushes downward on objects on earth is called gravity.
What may happen to a rocket which rises from the earth never attains escape velocity?
A rocket that doesn't reach "escape velocity" will be overcome by gravity and will be pulled back down to Earth. Also, rockets which go into orbit have not reached escape velocity. Escape velocity is what is needed to completely leave earth's gravity well.
What force causes the spacecraft to orbit the moon?
gravity pulls space craft towards it. It's engines make it go round, the engines have to push the space craft away from the moon to stop it being pulled down to the surface
Does your weight change when you go to another planet?
Yes, because on different planets you are being pulled down by a different mass. this help me so much
In which layer are cooler particles pulled down by gravity?
Convection zone
Cooler denser air is pulled down by?
Cooler denser air is pulled down by gravity but is also pushed down by the rising hot air. This process is called convection.
What is cooler air pulled down by?
The density of a cool gas is lower compared with the density of a hot gas; consequently the cooler gas is pulled down.
Is cooler and denser air pulled down by gravity?
Yes. But as they approach the Earth's surface, the air will become more compressed and thus warmer and even more dense.
Objects in projectile motion are pulled down by?
gravity
What is it called when soil is pulled down a hill by gravity?
landslide
What layer are cool particles pulled down by gravity?
ionosphere
Why does electrical wirings sag?
The simple answer is, "Gravity". Gravity pulls the wires down just as it pulls everything else down. The wires can only be pulled with a maximum tension, and all the while gravity is pulling down.
Why do people float in zero gravity?
Gravity is a force that pulls you down to the centre of a planet. If it was zero gravity you wouldn't be pulled down. Earth is the only planet that has gravity that's why you "float" in space. I hope this has helped.
Is rain a force?
No. What brings rain down, gravity, is a force. Rain is simply water being pulled down by gravity in little drops from clouds in the sky.
Why were rivers created?
Because water is pulled down by gravity and water erodes earth.
What happens to an object when it is thrown in the air?
it is slowed by liquid friction, and pulled to the ground by gravity
