Meteor impacts occur when meteoroids, which are small rocky or metallic bodies from space, collide with a planet or moon. When these objects enter the atmosphere, they can create bright streaks of light known as meteors. If they survive the journey and reach the surface, they are called meteorites. The size of the meteoroid determines the impact's effects, ranging from small craters to significant geological changes. These impacts can have various consequences, including the creation of craters, which are depressions formed on the surface. Notable examples include the Chicxulub Crater, linked to the extinction of the dinosaurs, and the Barringer Crater in Arizona. Meteor impacts can also trigger environmental changes, such as wildfires or tsunamis, depending on their size and location.
