Meteor Impact Craters Around the World

METEOR IMPACT CRATERS ACROSS THE WORLD EUROPE 39 IMPACT STRUCTURES NORTH AMERICA ASIA 58 IMPACT STRUCTURES 30 IMPACT STRUCTURES SOUTH AMERICA AFRICA AUSTRALIA IMPACT STRUCTURES 19 27 IMPACT STRUCTURES IMPACT STRUCTURES NAMING SPACE ROCKS COMET A chunk of ice and rock originating from the outer solar system often accompanied by a coma and tail. ASTEROID A rock in orbit generally between Mars and Jupiter. Sometimes gets bounced towards Earth. METEOROID A space rock that bigger than a dust grain but smaller than an asteroid. If it strikes Earth then it is then a Meteorite. МЕТЕOR The streak of light seen when a space rock enters the atmosphere and starts burning up. A.K.A "falling star" METEORITE If a meteor doesn't entirely burn up, a piece of space rock that lands on Earth is called a meteorite. TYPES OF METEORITES IRON primarily iron and nickel from the core of large asteroids Credit: Smithsonian institution STONY IRON Mixture of iron and stony material. Credit: CHONDRITE Most common type of meteorite; similar in composition to the mantles and crusts of terrestrial planets Credit: CARBONACEOUS CHONDRITE Very similar in composition to the sun but with less volatile components Credit:Chip Clark, Smithsonian institution ACHONDRITE Similar to terrestrial basalts; believed to have originated from another planet or asteroid Credit: Lunar and Planetary Institute DANGERS OF IMPACT Similar to terrestrial basalts; believed to have originated from another planet. A very large number of meteors enter the Earth's atmosphere each day. But most are just a few milligrams in size. The most dangerous asteroids, those capable of causing major disasters, are extremely rare. Meteor Diameter : UNDER 50 METERS ( UNDER 164 FT) Meteors disintegrate in the uppper Force ( megatons) : LESS THAN 10 atmosphere; most don't reach Earth's surface Interval (years): LESS THAN 1 Meteor Diameter : 75 METERS( 246 FT.) iron meteors make craters like Meteor Crater ( map ); stones produce airbursts like Tunguska (map); can Force ( megatons) : 10-100 Interval (years) : 1,000 destroy a small city irons will make craters stones produce 160 METERS (525 FT.) airbursts;can destroy a large urban area the size of New York or Tokyo METEOR DIAMETER : FORCE ( MEGATONS): 100-1,000 INTERVAL (YEARS) : 5,000 METEOR DIAMETER : 350 METERS ( 1,148 FT.) FORCE ( MEGATONS): 1,000 - 10,000 INTERVAL (YEARS) : 15,000 land impact can destroy an area the size of small state ocean impact produces mild tsunamis Land impact can destroy an area the size of Virginia ocean impact makes big tsunamis METEOR DIAMETER : 0.7 KILOMETERS ( 0.4 MILE) FORCE ( MEGATONS): 10,000-100,000 INTERVAL (YEARS) : 63,000 METEOR DIAMETER: 1.7 KILOMETERS ( 1.1 MILES) FORCE ( MEGATONS): 1,00,000-1,000,000 INTERVAL (YEARS) : 250,000 land imapact raises dust with global implications; can destroy an area the size of California or France.
