An analysis of the potential damage of meteorites in the surface of the earth

Throughout earth history, volcanism has been responsible for producing much of the water present on the earth's surface, and for producing the atmosphere earthquakes are one of the processes responsible for the formation of mountain ranges which which direct water to flow downhill to form rivers and lakes. 1 introduction barium is the fifth element within the alkali-earth column, with an atomic number of 56 and an atomic mass of 137327 u because of its electronic configuration, ([xe] 6 s2), the common forms of ba are ba(0) and ba(ii. Studies of earth's history indicate that about once every 5,000 years or so on average an object the size of a football field hits earth and causes significant damage. I am trying to figure out if a meteorite can reach the surface of earth can kill a human doing a damage similar, upon visual inspection, to that inflicted by a fire weapon.

an analysis of the potential damage of meteorites in the surface of the earth Collisions between asteroids in space create smaller asteroidal fragments and these fragments are the sources of most meteorites that have struck the earth's surface because they are readily available for study, many meteorites have already been subjected to detailed chemical and physical analyses in laboratories.

Laser-zapping of a globular, golf-ball-size object on mars by nasa's curiosity rover confirms that it is an iron-nickel meteorite fallen from the red planet's sky iron-nickel meteorites are a common class of space rocks found on earth, and previous examples have been seen on mars, but this one. A rock bed at the gillespie lake outcrop on mars displays potential signs of ancient microbial sedimentary structures image credit: nasa a careful study of images taken by the nasa rover curiosity has revealed intriguing similarities between ancient sedimentary rocks on mars and structures shaped by microbes on earth. For instance, of all the meteorites that have fallen to earth, approximately 4% were metallic so we can assume that 4% of near-earth asteroids are also metallic.

-origin of earth/solar system (lithosphere, hydrosphere and atmosphere) - 46 bya, earth and solar system formed by collisions of many meteorites (pieces of rock and metal) and comets (dirty ice balls. Meteor strike a meteor burst into a fireball over siberia the massive explosion occurs about 15 miles above the surface of the earth an asteroid has more damage potential on the ground. So i just did a back of the envelope calculation assuming a 10cm meteorite would be big enough to do some quite serious damage to a person, using the frequency from this paper for objects that size is about 1 every three days somewhere on earth, 133 a year, the surface area of earth according to google is 5151 trillion m 2 and i intend to live.

The following table summarizes by object the potential future earth impact events that the jpl sentry system has detected based on currently available observations click on the object designation to go to a page with full details on that object. A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon. The earth's atmosphere cannot prevent ground impact damage for stony meteorites greater than 200 meters in diameter for iron meteorites that impact at greater than 20 km/sec, the critical diameter is about 40-60 meters.

The fall of meteorites to the earth's surface is part of the continuing process of accretion of the earth from the dust and rock of space when these rock fragments come close enough to the earth to be attracted by its gravity they may fall to the earth to become part of it. These are really small meteorites that are sort of like dust specks that are continually raining down onto the surface of the earth if you set out a bowl of water or a petri dish with petroleum jelly in it, you'll catch of a few meteorites after some time - along with bugs, pollen, regular dust, etc. The largest meteorite found on earth is the hoba meteorite, discovered in namibia, africa and is estimated to weigh more than 132,000 pounds (66 tons), and the second largest is the el chaco, also.

  • It turns out that the earth's atmosphere is ineffective in preventing ground impact damage for stony meteorites greater than 200 meters (about 650 feet) in diameter for iron meteorites that impact at greater than 20 km/sec (125 mi/sec), the critical diameter is about 40-60 meters (130-200 feet.
  • Any surviving chunks of rock free fall to the earth's surface to be collected as meteorites the fireballs in the sky team at curtin university has an amazing network of cameras to track incoming fireballs and predict the final land location of meteorites - and work out where in the solar system they came from.
  • The rock is believed to have originated underneath the martian surface and to have been extensively fractured by impacts as meteorites bombarded the planets in the early inner solar system.

Note: many circular features on the surface of the earth some are formed by meteorite impact, many are not some are formed by meteorite impact, many are not for example circular features may be formed by the collapse of a volcanic magma chamber forming what is known as a caldera. Doom from above: the threat of meteorites an asteroid 10km in diameter wiped out the dinosaurs and extinguished life on earth the scientific community is working to avoid a repeat. The meteorite weighed an estimated 625 tons and exploded approximately 12 miles above the earth's surface [entry updated 3/9/2013] potential to damage people.
