Where do asteroid came from?
Asteroids are thought to have came from the left over bits and pieces of planets when they formed.
Where meteorites came from?
Meteorites can from asteroids that landed on Earth's surface. They were originally chipped off larger planetary bodies by bolide impact.
How much years ago the solar system came into being?
it came in about 13.7 billion years ago.
What is the composition of an asteroid belt?
An asteroid is a rock made of silicon, nickel, iron, or carbon, and revolves around the Sun. Asteroids are found throughout the solar system but many are in the asteroid belt between Mars and Jupiter. Some may be formed by breaking off from a moon or comet. The name comes from the Latin for "little starlike object", tiny glowing things in the sky. An asteroid is actually more like a small planet : rocks that are big enough to reflect enough light to be seen, but not big enough to be a proper planet. The largest of the asteroids is Ceres, which was promoted to "dwarf planet" at the same time that Pluto was downgraded to that status.
Are asteroids and comets the same thing?
okay i think that they are the same because arnt comets the same as shoting stars and shoting stars are just asterids that came to close to the earth so i think that they are the same. but you might want to ask someone before using this information im only 13. ok no! your way wrong soory bro.. comets have a tail... asteroids don't comets are made up of mostly rock and ice...and asteroids of rock and metals. and by the way, a shooting star is an meteor not and asteroid
Where did the ancestors come from?
Our ancestors came from Africa billions of years ago
What happens in cell?
the cell is self-replicating, and after billions of years, homo sapiens came.
How did rain start?
rain started as soon as water came to earth,because there is water there is the water cycle, evaporation,condensation and precipitation.In fact the water we all have today is the same water millions and billions of years ago because of the water cycle.
How does the water get into the sea?
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.
Did humans come from the ocean?
A long time ago, billions of years ago, creatures came from the sea unto land, and eventually they evolved into human beings. People did come from the sea, and it took billions of years of evolution for that to happen.
Where do asteroid came from?
Asteroids are thought to have came from the left over bits and pieces of planets when they formed.
What was the best moment of 2008?
Well, that question can have billions upon billions of answers, mine is when the movie Twilight came out.
How did water came on this earth?
There are various theories as to where all the Earth's water came from, but several theories have fared better than the others. We know that the oceans existed as early as 100 million years after the formation of the Earth. When the Earth was in the process of forming, with a radius just 40% smaller than at present, it would have had enough gravity to hold on to a tenuous atmosphere with watervapor. The first water vapor on the planet would have come from the planet's internals, where volatile (low weight) chemicals would have a tendency to float to the top, and heavy chemicals (iron and nickel) would sink. Though the first of Earth's water came about through volcanism, this alone probably didn't produce enough to form stable pools on the surface. More water was added to the planet during several hypothesized large impacts from asteroids from the outer asteroid belt. Comparing the isotope ratios of water on Earth and water from comets and asteroids has revealed that the majority of the Earth'swater comes from asteroids.
How long as hell been around before earth?
Hell is a human construct (it's not even in the bible), so the Earth came first - by billions of years.
Where did asteroids came from?
Current theory is that the asteroids formed along with the rest of the planets, until Jupiter reached its current mass, at which point gravitational resonance caused ejection and/or disruption of most of them.
What is Cambrian's Big bang?
I assume you are referring to the Cambrian Explosion... It was a period on Earth many millions of years ago after heavy bombardment from asteroids. A huge "explosion" of species and life came to form on Earth.
What does asteroids mean in science?
its a big flying rock in space that came from other plantes when the universe was created
