    4. 4. Feb 15, 2013 MOSCOW—A meteor streaked through the sky and exploded Friday over Russias Ural Mountains with the power of an atomic bomb, its sonic blasts shattering countless windows and injuring hundreds of people. The spectacle deeply frightened thousands, with some elderly women declaring the world was coming to an end. The meteor — estimated to be about 10 tons — entered the Earths atmosphere at a hypersonic speed of at least 54,000 kph (33,000 mph) and shattered about 30-50 kilometres (18-32 miles) above the ground, the Russian Academy of Sciences said in a statement.

    17. 17. Meteoroids, Meteors and MeteoritesMeteoroid – a piece of rock moving through space (smaller than asteroids, likely rocky chunks that have broken off of asteroids and planets)
    18. 18. Meteoroids, Meteors and Meteorites ... What is this a picture of?
    19. 19. Meteoroids, Meteors and MeteoritesMeteor – a meteoroid that enters Earth’s atmosphere and burns up (Shooting stars are meteors)
    20. 20. Meteoroids, Meteors and MeteoritesMeteorite – a meteoroid that passes through Earth’s atmosphere and reaches the ground without burning up.
    21. 21. Asteroids• An object that ranges in size from approx. 1km to 50km wide• Found in the asteroid belts
    22. 22. Asteroid and Meteorite Impacts65 Million Years Ago – an asteroid the size of amountain struck the Earth, some scientists believethis caused a mass extinction of thousands ofspecies
    23. 23. Asteroid and Meteorite ImpactsVredefort Crater-largest and oldest crater-South Africa-diameter = 250 km-2 billion years old
    24. 24. Asteroid and Meteorite ImpactsManicouagan Crater-fifth largest crater-Quebec, Canada-diameter = 70 km-212 million years old
    25. 25. Asteroid and Meteorite ImpactsClearwater Craters-two lake-filled craters-Quebec, Canada-diameter = 32 km(West crater) & 22 km(East crater)-290 million years old
    26. 26. Asteroid and Meteorite ImpactsChicxulub Crater-third largest crater-Yucatan Peninsula,Mexico (mostlyunderwater)-diameter = 170 km(size of a small city)-65 million years old(time of extinction ofthe dinosaurs)
    27. 27. Asteroid and Meteorite ImpactsJune 30th, 1908– an object hit in Siberia and destroyed an area larger than the whole city of Kingston Ontario
    28. 28. CometsAn object composed of rocky material, ice, and gaswhich orbits the sun.Has 2 tails – one of gas/water vapour, and one ofdust.
    29. 29. CometsThe radiation from the Sun releases gases andparticles in the comet and the tails form.
