What Happened to the Dinosaurs?

7. An Asteroid or Meteor

One of Science’s most common theories on the extinction of dinosaurs involves a meteor or asteroid hitting the earth with such great velocity that its impact wiped them all out. When an asteroid collides with the Earth's surface, the kinetic energy of its motion is converted into explosive energy. This blows out debris, dust, rocks, and a mass of energy that far surpasses the area of impact. As well as all of this debris being blown into the planet, it would have also sent it into the atmosphere. With so much dust shrouding the Earth's orbit, the sun would have been blocked out for years, plummeting the planet into cold and darkness. As well as this, scientists have also more recently calculated that, after the impact, the debris could have also rained down balls of fire all over the world.
