Many objects collided with Earth during its formation, ranging in size from dust grains to small planets. The one believed to be responsible for the formation of the moon was about the size of Mars.
The earth is still forming!
As far as I know, they still aren't quite sure on that. One theory that I believe has been recently disproven is that we collided with a Mars sized object in the early formation of the solar system and that became the moon. However, the chemical composition of the moon's soil is very similar to that of the earth, so I believe the most credible theory is that we were involved in some sort of collision very early on while things were still forming and a piece of the earth became the moon
Scientists believe that the layers of the Earth were formed through a process called differentiation, where heavier materials sank towards the center, forming the core, while lighter materials rose to the surface, forming the crust. This process occurred early in Earth's history when the planet was still molten, allowing for the separation of materials based on their density.
Your mass remains the same regardless of where you are in the universe. So, if you weigh 25kg on Earth, you would still weigh 25kg in space. Weight is a measure of the force of gravity acting on an object, while mass is a measure of the amount of matter in an object.
It would still weigh 100lbs, though the gravity on Io would affect its apparent weight so you could lift it like was about an 18 lb weight on earth.
The moon formed when a Mars-sized planet collided with Earth when the solar system was still forming, ejecting a portion of Earth into orbit. That rocky debris came together to form the moon.
The moon was thought to have formed 4.527 billion years ago, when a large planetoid the size of mars collided with the earth, as the solar system was still in its infancy. The remains of this impact went into orbit around the Earth, forming into the moon we have today.
Billions of year ago, when the Earth was still molten, a Mars-sized object collided with Earth ejecting material into orbit. This material coalesced to form the Moon. The Moon was once much closer to the Earth, but due to the tidal bulges of the Earth and Moon, the Moon moves farther away (about 1.5 inches) every year.
The earth is still forming!
Well yes and no the coal was forming just a tiny bit only it was still not giantly flowing like today.....
No, it has the speed of the spinning earth.
Assuming you meant 'Why does the moon orbit earth as opposed to the sun?'The moon is still quite mysterious to us and there are multiple possible theories out there regarding its creation. But the moon is a natrual satellite of the earth, same as the moons of the other planets in our solar system. The currently accepted theory of how the moon came to be is that another planet, similar to Mars, collided with Earth in the early solar system, resulting in debris and rocks forming in orbit around our planet, later forming into the shpere that is our natrual satellite. As the moon was formed around Earth and pulled into our orbit, it stayed there, as Earth's gravitational pull is stronger than than that of the moon.
There are several theories out there for the formation of the moon. The current most widely accpeted one is called the Giant Impact Hypothesis. The basic idea is that at some point after the young earth had formed but while the surface was still molten a Mars sized object collided with Earth and the material ejected and began orbiting the Earth. This material later formed the Moon.
By comparing the object with a stationary object. For instance, we are standing apparently still on earth, yet by comparing our position against the sun and stars, we have proof that the earth is actually moving.
Scientists believe that the water on earth came from icy comets that collided with the planet. This would have mainly happened billions of years ago when the earth was still quite young, and when bombardment from such bodies was more frequent.
As far as I know, they still aren't quite sure on that.

Thee are three theories: 1) spin-off:when Earth was young and still cooling, a piece of Earth broke off at the eqautor while Earth was spinning rapidly 2)Capture-Earth captures a passing moon 3)Collision- A planet (orpheus) collided with Earth, creating fragments. The fragements came back together creating the new Earth with a moon. This is the accepted theory.
