the earth is a oblate spheroid....we do not fall to the edges because of the gravitational pull...

Yes, there is gravity at the center of the earth, but it would exert the same force in all directions at once, resulting in a net acceleration of zero.  Therefore, yes, you would float in the same manner as if you were in outer space.

Gravity is an inverse square law for the further you are from the centre of mass the lower the graviational pull you feel. So yes gravity is less on the top of a mountain (and this has been measured) also these would be less air resistance as the air is of a lower density. These two factors would allow you to jump high, assuming you were on oxygen.

earth is weightless in space. \n but your concept is interesting as applied to mass. gas also has mass so I do not think anything ever disappears. it just changes form. the gravity of the earth is what causes "weight" so the gravity of earth hangs onto the gases that develop and we all may strangle in them, but the earth and its atmosphere inclusive do not lose mass overall. saturn is a planet whos major mass is gases with a tiny ball inside of solid rock, about the size of earth. maybe we will gradually warm to a  huge gasball with a tiny rock in the middle with one person left on it smoking a cigarette and sitting in his motorhome with the motor running.

If we assume the Earth is a perfect spehere, the gravitational accleration would, indeed, be equal at any point along the surface of the sphere.\nWhen you take the rotation of the Earth into account, yes, at the equator, an object's "weight" is less than it would be at the poles.\n\nThe gravitational acceleration acts as the centripetal acceleration which keeps us all on on the Earth instead of flying out into space in a straight line.\nAt the poles, no centripetal acceleration is needed (neglecting Earth's revolution around the sun), but at the equation, the objects inertia acts to lessen the appearent effects of gravity and reduce its weight.  This is NOT due to the fictitious centrifuga force.

The earth is APPROXIMATELY round due to gravitational forces.

Things would weigh less than on earth\n\nst

the reaction of gravity is movement, if the object is bigger than earth then it will attract earth and earth will react

gravity at the earth's surface = 9.80 m/s^2

Gravity is the force that pulls things on to Earth.\nWeight is how heavy something is.\nThey are related because gravity pulls down weight on to the Earth. \nhope this helps!

because the earth is causing the gravity... everything in space has gravity. How much gravity depends on the objects mass. Bigger mass bigger gavitational pull.

Gravity also decreases with altitude (since greater altitude means greater distance from the earth's centre). All other things being equal, an increase in altitude from sea level to the top of Mount Everest (8,850 metres) causes a weight decrease of about 0.28%. It is a common misconception that astronauts in orbit are weightless because they have flown high enough to "escape" the earth's gravity. In fact, at an altitude of 250 miles (roughly the height that the space shuttle flies) gravity is still nearly 90% as strong as at the earth's surface, and weightlessness actually occurs because orbiting objects are in free-fall.

Gravity is a force of attraction that acts between bodies that have mass. It is a physical phenomenon of fundamental importance, profoundly affecting the workings of the world around us and the universe beyond. Most familiarly, it is the gravitational attraction of the earth that endows objects with weight and causes them to fall to the ground when dropped. In fact, gravity is also the reason for the very existence of the earth, the sun and other celestial bodies; without it matter would not have coalesced into these bodies and life as we know it would not exist. Gravity is also responsible for keeping the earth and the other planets in their orbits around the sun, the moon in its orbit around the earth, for the tides, and for various other natural phenomena that we observe.\n\nIn common usage "gravity" and "gravitation" are either used interchangeably, or the distinction is sometimes made that "gravity" is specifically the attractive force of the earth, while "gravitation" is the general property of mutual attraction between bodies of matter. In technical usage, "gravitation" is the tendency of bodies to accelerate towards one another, and "gravity" is the force that some theories use to explain this acceleration.\n\nGravity was rather poorly understood until Isaac Newton formulated his law of gravitation in the 17th century. Newton's theory is still widely used for many practical purposes, though for more advanced work it has been supplanted by Einstein's general relativity. While a great deal is now known about the properties of gravity, the ultimate cause of the gravitational force remains an open question and gravity remains an important topic of scientific research.\n\nContents [hide]\n1 Overview of the history of gravitational theory \n2 The Earth's gravity \n2.1 Comparative gravities of the Earth, Sun, Moon and planets \n3 Mathematical equations for a falling body \n3.1 Gravitational potential \n3.2 Acceleration relative to the rotating Earth \n4 Gravity and astronomy \n4.1 Self-gravitating system \n5 Practical uses of gravity \n6 Newton's law of universal gravitation \n6.1 Acceleration due to gravity \n6.2 Bodies with spatial extent \n6.3 Vector form \n6.4 Gravitational field \n7 Problems with Newton's theory \n7.1 Theoretical concerns \n7.2 Disagreement with observation \n7.3 Newton's reservations \n8 Einstein's theory of gravitation \n8.1 Experimental tests \n9 Comparison with electromagnetic force \n10 Gravity and quantum mechanics \n11 Alternative theories \n11.1 Recent alternative theories \n11.2 Historical alternative theories \n12 Notes \n13 See also \n14 References \n15 External links \n \n\n\n[edit]\nOverview of the history of gravitational theory\nThe first mathematical formulation of gravity was Isaac Newton's law of universal gravitation, published in his 1687 work Principia Mathematica. Professor William Whewell of Cambridge University, author of History of the Inductive Sciences (1837) stated:\n\n"The law of gravitation is indisputably and incomparably the greatest scientific discovery ever made, whether we look at the advance which it involved, the extent of the truth disclosed, or the fundamental and satisfactory nature of this truth." [In A Treasury of Science ed. Harlow Shapley et al, Harper & Bros. NY: 1946] \nAlthough the law of universal gravitation was first clearly and rigorously formulated by Isaac Newton, the phenomenon was observed and recorded by others. Even Ptolemy (c. 100-178) had a vague conception of a force tending toward the center of the Earth which not only kept bodies upon its surface, but in some way upheld the order of the universe. Indian astronomer Brahmagupta (598-668), who followed a heliocentric solar system, was the first to recognize gravity as a force of attraction. He explained that "bodies fall towards the Earth as it is in the nature of the Earth to attract bodies

If the Earth's radius were bigger, and the mass of it stayed the same, then you would weigh lighter.  That's because with a bigger radius, you're farther away from the centre of gravity, therefore less pull.  If the mass change, then the situation would be different.

Due to Newton's Law of Gravitational Force (see link), as the distance between two objects decreases, the gravitational force will increase exponentially.  \n\nIt all depends on your position in reference to the center of mass.  If you are on the surface of the earth, your distance from the earth is normally defined as the distance from you to the center of the earth, or center of mass.  \n\nAs you get closer to the center though, the force due to gravity changes differentially since your position in the mass itself is changing and gravitational forces are acting on you from various directions (the earth can be thought of as a sum of different aggregate masses at this point).  Therefore, the gravitational force of the earth will be "less" at the center, since the sum of all aggregate forces would be acting in opposition of each other.  However, since gravity is a relatively weak force, it would not be your biggest concern, because, at the center of the earth, it's not the force of gravity on you that matters, it's the pressure and temperature that will kill you.\n\nMagnetic and gravitational forces are completely separate types of forces and should not be considered in the formulation of this answer.

The Earth is a balanced system. Changes within certain parameters may sway the system this way or that, but won't throw it out of balance completely. \nSo yes, the Earth can compensate for changes caused by global warming, but only to a certain extent.
