If the gravity on Earth were to decrease, the mountains would be taller, but less compacted.
The streams would flow slower for a given gradient.
All the masses would weigh less, including you.
The atmosphere would extend higher, and may carry more water vapour.

Why do gravity decreases towards the core of the earth?
Gravitational attraction is caused by the mass of the earth. As you go down in the earth, the amount of mass of earth still between you and the centre of earth decreases. Thus as this effective mass decreases, the gravitational attraction decreases.
Are the forces between Earth and the Moon a Newtonian third law pair?
Yes. The gravitational forces between the Earth and moon are equal and opposite ...just like the gravitational forces between everytwo objects are.
What happens to the source of gravity as you leave earth?
If we consider classical physics (Newtonian explanations) the source is unaffected. The strength of the gravitational pull decreases as the second power of the distance.
How would you expect earth's gravitational pull on you high in the Rocky Mountains to be different to be from a pull on a sea shore?
The earth's gravitational pull decreases as altitude increases.
What forces affect tides?
Tides are caused by the gravitational forces on Earth from the Moon and the Sun.
What forces act upon a meteor as it falls toward Earth?
Forces of gravity ( gravitational force) pulls the meteor to earth
What happen to the force of gravity when you get further from the earth?
As you get further away from Earth, the gravitational forces between you and Earth decrease. But the gravitational forces between you and something else might increase, like between you and the moon, or between you and the sun.
Does the gravitational attraction between earth and an asteroid decrease as the asteroid approaches earth?
The gravitational force (or attraction) between any two objects increases as the distance between them decreases. Thus, as an asteroid approaches Earth, the Earth's gravitational pull will increase as it gets nearer.
Where does the heat in the earth's inner core come from?
Friction from gravitational forces.
What is water that flows due to the gravitational forces among earth?
Tides?
Is earth perfectly balanced if not why is it not?
No, because of shifting masses on and within the earth and external gravitational forces.
What happens when gravitational force changes?
If gravity force of earth changes,1.The things which adhere on the surface and atmosphere will get definitely disturbed.2.The matters which are within the gravitational field will experience the dislocation.3.The cosmic ray intrusion to the earth will change drastically.4.The weight of the matter around the whole world will change.5.The escape velocity of the earth will change.6.The moon will collide on earth, if gravitational force increases and the moon will move away from the earth ,if gravitational force decreases .If this happen then life in earth will be destroyed.
