How was Mercury (planet) formed?

[Emma]

I'm writing a report on Mercury, and one of the requirements is that we write about how/when Mercury was formed. I was wondering if you could please let me know the answers, or give me a good site (preferably) that will help me out. Thanks so much!!

I don't remember signing up for the beech volunteering committee.

"Mercury's history of formation is similar to that of Earth's. About 4.5 billion years ago the planets formed. This was a time of intense bombardment for the planets as they scooped up matter and debris left around from the nebula that formed them. Early during this formation, Mercury probably differentiated into a dense metallic core, and a silicate crust. After the intense bombardment period, lava flowed across the surface and covered the older crust. By this time much of the debris had been swept up and Mercury entered a lighter bombardment period. During this period the intercrater plains formed. Then Mercury cooled. Its core contracted which in turn broke the crust and produced the prominent lobate scarps. During the third stage, lava flooded the lowlands and produced the smooth plains. During the fourth stage micrometeorite bombardment created a dusty surface also known as regolith. A few larger meteorites impacted the surface and left bright rayed craters. Other than the occasional collisions of a meteorites, Mercury's surface is no longer active and remains the same as it has for millions of years"

Presumably it was formed by hot dust and gas which collected together while circling the Sun. Obviously gravity would have played an important role.

looks like it's your job to find out

What the heck? Why don't kids do their own research anymore? Get an encyclopedia.

let's say on second thought, GOD?
