The equator
Any part that is "away" from the gravimetric center of the earth is up. Any part "above" that center of gravity is up.
You are leveling the line 90 degrees to the center of the Earth. If your line isn't level, the bubble will rise away from the center of the earth.
any direction. you can go any direction to get out of the center of the earth, but the center is to hot for humans, so dont try it
As you move away from the center of the Earth, your weight will decrease. This is because weight is the force of gravity acting on an object, and gravity weakens with increasing distance from the center of the Earth.
They do not; the Earth is well away from the center, in one of the spiral arms of the galaxy.
approximatley 25,000 Light Years away
Assuming that the atmosphere is distributed evenly all over the Earth, its center of mass is of course at the Earth's center. If for any reason there is more atmosphere on one side than on the other, the center of mass would be slightly away from Earth's center.
No. The black hole at the center of the galaxy is too far away to affect earth.
The acceleration due to gravity decreases as you move farther away from the center of the Earth. This is because gravity weakens with distance according to the inverse-square law.
About 25,000 light years away...
No, if someone went into the center of the earth, they will find a relaxing place to let all their trobles drift away... DUUUUUUUHHHHHhhhhhh of corse you would die!
The center of mass of Earth is located beneath the surface of the Earth, about 4,671 kilometers (2,900 miles) away from its surface. This means it is not within the atmosphere, which extends only a few hundred kilometers above the Earth's surface.
