the further you are from the center of the earth, the less the pull of gravity.

so you weigh less on a mountain than at sea level, and get heavier the further you get towards the center of the earth.

I don't understand this, because when you get closer to the center of the earth, doesn't the mass of the earth above you not count towards gravity anymore? so referring to the picture, when you're at about that point [A] equal to the size of the moon (or mass i guess would be more accurate) inside earth, isn't the gravity on you roughly the same as the moon [B]?

so you're saying that since the earth is more dense the further you get to the center, that's why they say "you get heavier when you move towards the center of the earth"

thanks for the clue, that makes sense i didn't think of that. it still doesn't clear it up for me though, because it still seems to me you'd be lighter near the center than you'd be at the surface, albeit the center is more dense
