If you jump up, for example, with a momentum of 100 kilogram x meter / second (this can be done by jumping up at a speed of 2 meters/second, if you have a mass of 50 kilograms), then the Earth will recoil by the same amount of momentum - in the opposite direction of course. This follows directly from Conservation of Momentum.
Since the Earth is rotating, and moving through space, and the rock is moving along with the Earth, then it does, but relative to the Earth, I'd say that the momentum of the rock (mass * velocity) is essentially zero.
For a simple answer, we have to ignore air resistance. As the skydiver's downward momentum increases, the earth's upward momentum increases by an identical amount. The total momentum of the earth-skydiver system remains constant.
Mercury has the largest core relative to its overall size among the terrestrial planets. The core makes up about 85% of Mercury's radius, compared to about 55% for Earth's core size relative to its radius.
Simply because physicists discovered that it is a product that is conserved. In collisions of two objects for example, if you add up the momentum before the collision the momentum will be the same after the collision. Note that momentum is not something that has a concrete reality. A rock sitting on the ground has zero momentum relative to us here on earth but has alot of momentum relative to someone on mars. It can not have zero momentum and alot of momentum at the same time, it depends on ones frame of reference. My point is that momentum is not at 'concrete" thing.

More or less. There is a law of conservation of angular momentum, according to which Earth can't gain or lose angular momentum on its own - if for example it loses angular momentum, it has to go somewhere. A meteor who falls into the Earth, or a rocket leaving the Earth can change Earth's angular momentum - but the total angular momentum (e.g., of the system meteor + Earth) is the same, before and after the impact.

Jupiter. It has the largest moon in the solar system called Ganymede. The earth has the largest moon relative to its size though.

Saturns relative size to earth is 4,590 million square km.
Antarctica is the fifth largest continent on earth, and is about the size of USA and Mexico, combined.
Mercury has the largest core relative to its overall size among the terrestrial planets. The core makes up about 85% of Mercury's radius, compared to about 55% for Earth's core size relative to its radius.

Yes, momentum is conserved in the larger apple-Earth system. When the apple falls towards Earth, it gains momentum in the downward direction while Earth gains an equal amount of momentum in the opposite direction. The total momentum of the system remains constant, demonstrating the principle of conservation of momentum.
impulse (force x time) is equal to momentum (mass x velocity); Ft=mv
well, earth has the largest moon relative to the planet it orbits
This can be a tricky question; before answering one like this ask for the frame of reference.If you are in a closet with a floating feather, and a ball on a shelf, and measure momentum relative to the closet, the feather will have more momentum than the bowling ball.However, if you look at the larger picture, you will find thatthe earth is rotatingthe earth is orbiting the sunthe sun is moving relative to other stars near usthe sun is orbiting our galaxyour galaxy is moving relative to other galaxies.Every one of these motions involves momentum, and the total momentum is shared out among everything on or in this planet in proportion to its mass. The bowling ball is enormously massive compared to the feather, and has vastly more momentum in the universal frame of reference.The answer is correct, but the last sentence is wrong. There is no universal frame of reference.
Momentum is conserved in a closed system, so when a falling ball strikes the Earth, the Earth will experience an equal and opposite force from the ball, resulting in a transfer of momentum. The total momentum of the system (ball and Earth) remains the same before and after the collision.
