We would all die and we would have to kill each other for supplies so get your shotguns ready.
That depends on where you are on the Earth and where the meteor hits. ________________ Wherever you are on earth, if an object the size of the earth collided directly with us (at that size it would be a rogue planet, I think, rather than a meteor) then certainly all life on earth would come to an end, and likely within minutes.
it is
From the size of a grain of sand, to about the size of a grain of rice. A meteor the size of e kernel of corn would be rare. Bigger ones do come along, but things the size of a baseball probably only hit the Earth once a week or so.
When an asteroid enters the Earth's atmosphere, it is considered a meteor. Usually, depending on the size and mass of the asteroid, it will burn up in the Earth's atmosphere. If it is really big, or high in mass, or both, it will penetrate the atmosphere, thus making an impact crater on Earth. When it does this, it is now considered a meteorite.
It already does happen on Earth but just not that offten.The size doesn't matter.
It'd be bad on earth
If a baseball size meteor entered our atmosphere, it would get burned up and not hit the ground. Most meteors that strike the Earth hit at around 20 km/s, therefore if a baseball sized meteor actually hit the ground, it would release roughly 10^9 joules of energy. That's roughly equal to the energy released by the explosion of 1000 kg of TNT.
Which degree of decreasing are you talking about ?
No, a single meteor would not be able to take over the whole state of Florida. Meteors are space rocks that burn up in the atmosphere or impact the Earth's surface in a localized area. The size of a meteor would not be large enough to cover an entire state like Florida.
A depression in the earth's surface caused by a volcano or meteor impact or other explosion is known as a crater. Craters can vary in size and depth depending on the force and size of the impact.
If the meteor was large enough it might significantly affect the environment as to make life difficult. It would have to be extremenly large (moon size) to destroy the earth. However no asteroids of this size exist in our solar system.
The orbit of a meteor depends on the size of the meteor. Different meteors have different orbits and it is hard to calculate its size.
