How often do meteorites enter the earth's atmosphere and land intact on earth?
What size is the biggest meteorite ever found and where? In which country are you most likely to find a meteorite ?
Answers:
Land often. Never intact, just some do not burn up entirely and do land. There are literally tens of thousands of different specimens known.
The Hoba, Namibia meteorite that weights around 60 tons and is about 3 meters in diameter is often considered the biggest.
Numerous satellite photographs helped the scientists discover the world's biggest meteorite site (with more than a hundred traces of crashed meteorites) in the region of Egyptian-Lebanese border. (from Pravda)
they barely come so not many people will know. last one i heard of was in texas or something.
few times a day. I think antarctica is the best place.
All the time, like every 3 seconds or something. Most of them land in my back garden. Oh no sorry that's my neighbours throwing stones at my cat.
They come quite often and are evenly spread over the world. They are not easy to recognize, as they look much like any other rocks, so the best places to look for them are in Antarctica or some other place, where there are no rocks on the ground to begin with.
Meteorites come in all sizes, from the very tiny - about 1000th of a millimetre across - to the very large - bigger than a house. The smallest ones - micrometeorites - fall all the time: approximately 40,000 tonnes fall on the Earth each year. This sounds like a lot of dust, but the grains are so small that we do not notice them. Bigger meteorites fall less frequently: about 1,000 meteorites the size of a football arrive at the Earth each year - but many are lost because they fall into the sea. The very big ones only fall every million years or so.
The biggest meteorite that landed as a single whole piece, and that is still in the place where it fell, is at Hoba in Namibia. It is about 3 metres square and 1 metre in height, and is calculated to weigh about 60 tonnes. It is a national monument.
Im not 100% sure, but i think the earth's outer atmoshphere is pretty much bombarded by smaller meteorite and space debries quite regularly, but they are too small to make any great impact and burn up in the atmospheric levels
It depends on the size of the particle as it enters the Earth's atmosphere. If it it large enough (& if it is also entering with the Earth's movement around the Sun, then it has less "speed" than if it entered against the direction of rotation) then the friction so produced by its velocity, will be insufficient to burn the item to gases, thus allowing it to land intact.
The large crater in Arizona(?) USA is a Meteor Crater.Another one landed in Sberia early in 1900 and caused widespread devastation.
They impact all the the time, i have heard that the Earth gains approx 2000 tons per day from Space debrie, so you could say the Earth has a weight problem!
Which is the least polluting form of transport?
statisticaly speaking a chocolate fireguard is 100% safe, disprove me ?
why is he in my bath?!?
why is the sea blue and salty?
What wind speed constitutes a storm. Same question for a gale. Have asked this before,but missed the answer?
if i left my house and went in a stright line how many miles untill im back home?
Why recycle, when we can leave it in landfill for future generations to find this valuable glass etc?
how to harnes the power of radio waves?
