It causes the air to remain by the planet Earth in the first place. Also, it causes the air pressure; about 100,000 Pascal (Newton per square meter) at sea level.

Explain how earths gravity affects objects that are on or near earth?
All mass attracts all other mass, thats a fact. The force due to gravity between the earth and another object, is dependent on their combined mass (earth and object), and the square of the distance between the centres of gravity.
What force causes all types of mass movement?
Gravity causes all types of mass movement. Mudflows, landslides, creeps, and slumps can all be causes by gravity.
What cause air pressure?
Gravity pulling the mass of the atmosphere toward the center of the earth. Atmosphere includes air, water vapor, etc.
Does earth's molten core affect gravity?
First: The earths core is not molten, it is a very dense solid mass, kept solid by the intense pressure on it. Second: It is the layer around this core that is molten, and yes it does influence gravity, but more so earths magnetism.
What produces the earths gravity?
Earth's gravity is caused by its mass (or rather its energy). Everything that has mass will passively generate a gravitational field, even you and me! (Although we are not by far massive enough for the gravitational attraction between us to be noticeable.) It is not caused by the Earth's magnetic field, or the Earth rotation (in fact the rotation counteracts gravity in some places).
Why air pressure from earths atmosphere is not the cause of gravity?
Gravity is an entirely separate entity which is a consequence only of the mass of the earth itself. In fact, the atmosphere presses down because gravity is pulling on it.
When does gravity change?
Gravity is caused by mass. Everything causes gravity but the bigger it is and more mass it has the more pull is felt by its gravity. So you are pulling the earth towards you and the earth is pulling you. The earth is much bigger and has more mass, so it pulls much more. Gravity gets weaker the further away you get from its source. The earths crust does not have the same mass all over, so some areas have slightly less gravity than others. The differences between areas are very very small. The moon has only a quarter the mass of the earth, so gravity on the moon is a quarter of earths gravity.
Does gravity decrease or increase if earths mass doubled?
More mass --> more gravity.
What is responseable for earths gravity?
Earth's mass is.
Is it true that the greater the earths mass the greatest its gravity?
It is true that mass and gravity are proportional to one another.
What is the amount of force of gravity pulling down on an object?
mass of object *force of gravity
Why is the gravity on the moon less than the gravity on earth?
Because the overall mass of the moon is less than the earths mass. The gravity of a body relates to the mass of that body.
What is the force of gravity pulling on your mass measured in newtons?
weight
What is a specific mass ratio?
A specific mass ratio is the amount of gravity pulling on an object.
What is specific mass ratio?
A specific mass ratio is the amount of gravity pulling on an object.
Earths gravity is large because earth has a large?
Mass.
Why is earths gravity stronger than an apples?
Gravity is affected by the mass of an object, The greater the mass, the greater the gravity. Apples have gravity, but because they have such a small mass the gravity is tiny, whereas Earth has a huge mass which in turn means that it has a huge and noticeable gravity.
