Target 7 Explain the difference between a meteor and meteorite.
What is a Meteor? A Meteor is a Comet or Asteroid that completely burns up when it enters the Earths atmosphere As the Comet or Asteroid burns up, a streak is left behind. This sometimes known as a “shooting star”
What is a Meteorite? A Meteorite is a Comet or Asteroid that does not completely burn up when it enters the Earths atmosphere. As a result the comet or asteroid lands on the Earth’s surface. This is known as a “meteorite”
The largest Meteorite found in the USA. Discovered in 1902
What is more likely going to be a meteor or a meteorite? Due to their composition, comet is more likely to burn up in the atmosphere while an asteroid is more likely to make it to the Earth’s surface
Target 8 Analyze the impact that meteorites of varying size (meteoroid and asteroid) have on the Earth.
Meteoroid A meteoroid is a chunk of rock, metal, or dust in space.
Meteorite Meteoroids that survive as they pass through the atmosphere and hit Earth’s surface are called meteorites.
Barringer Meteor Crater, Arizona A meteorite can make a hole, or crater, in the ground when it hits it. The larger the meteorite, the bigger the hole.
- Scientists think that the crater was formed sometime between 25,000 and 50,000 years ago by an iron meteorite, somewhere between 30 and 100m in diameter, weighing roughly 60,000 tons. - The energy released by the impact was roughly equivalent to 3.5 million tons of TNT.
Most Meteorites are small, however there are scars of larger scale meteorites still visible today.
