does the earth weigh any more than what it did millions of years ago?

If one could actually weigh the Earth, the answer would be yes because the mass has increased over the past millions years due to falling of metorites onto the Earth's surface. I forget how many metorites fall onto the Earth each day but it is in the thousands. Most burn up in the atmosphere, but the atmosphere is part of the Earth and the resulting material is added to the balance of the mass.

It will pretty much look the same. Normal plate techtonics\nmoves continents very very slowly and you need more then a\nthousand year window to see any real difference. Just look\nat maps from the year 1006 if you don't believe me.

No, living things 're'turn to dust, meaning that the net weight gain is 0.  The Earth's mass does increase slightly (relative to the size of the Earth) from all of the space dust and meteors that constantly burn up in the atmosphere and fall to the ground.

You need to be more specific.\n\nWhat exactly do you mean by "Size"? Do you mean if Earth has the same mass as Jupiter, the same Volume as Jupiter, Both?\n\nIf Earth had the mass of Jupiter but the same volume as it has today, gravity would be much stronger.  The force of gravity is largely dependent on the distance away from the center of mass, thus we would be much closer to a larger center of mass.....we would weight A LOT more.\n\nIf Earth has the same mass as it does today, but had the volume of Jupiter gravity would seem to be a lot weaker.  We would be farther away from the Earth's center of mass and gravity would have a weaker effect on us, we would be much lighter.\n\nIf Earth has the same volume and mass as Jupiter, we would weigh more since the increase in volume is more than canceled out by the (excuse the term) massive increase in mass.

the earth is about 4.5 billion years old

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.

I think its not that earth is bearing any weight.When you put something like a block on the earth,earth exerts a force on the block.BUT the block also exerts the SAME force on the earth.So \nthe earth and the block are attracting each other,or are pulling each other with the same force.Therefore, no matter how much wieght you put on the earth,that thing will also attract the earth with same force.(So Earth wont ever fall!).I hope this helps.

The Earth would weigh the same. The material you used to build the wall would come from the earth, yet just be relocated.

If an object has mass, then it exerts gravity. The larger the mass the more gravity it exerts. Earth exerts gravity, but so does the moon, and the sun. The sun exerts a lot more gravity because it has more. Weight is a function of mass and gravity. So if you're asking about weight of earth, then in relation to what?

no.  it changes over millions of years as the universe changes and our relationship to the sun changes, but i'd guess it was pretty close as to what is now.

No. You can understand the difference by going back to its source: the Newton's Second Law.\n\nF = ma\n\nThe weight of an object is the attractive force (F) exercised by the Earth on that object.\n\nAs the above equation shows, the mass (m) of an object is the constant of proportionality that links any force exercised on the object with the consequent acceleration (a).\n\nSo you see that the weight is a special case of force, that you have when a is the Earth's gravity acceleration. \n\nNow suppose you bring the same object on another planet, say Mars, where the gravity acceleration is different. Its mass doesn't change, but the weight does!\n\nThe weight of an object is an Earth accident, while its mass is a more fundamental concept because its value remains constant (at least within the non-relativistic limit, but this is another story).

No, the Earth moves around the sun at a rate of once per year.\n\nReligion cannot beat fact.

No, they have ice cores from it that go back 100,000 years. Its edges were a little less icy up to about 600 years ago.

Scientists say that the Earth is about 4.5 billion years old. The oldest rocks that have been found are 3.8-3.9 billion years old. They actually think the Earth is 4.55 billion years old to be specific. Just to let you know i got it off  a website.

Well, maybe a little, but if they have it, it is really old and altered.  Below is a link to the geologic map.

Around 4.57 billion years old.

Matter and energy is constant in the Universe.  The fact that more people are born doesn't necessarily mean that the total mass of all compounds on the Earth has increased.  The compounds have simply been redistributed.  Therefore there would be no increase in weight
