* Erosion and Plate Tectonics: Earth is a very dynamic planet. Over time, erosion from wind, rain, and glaciers, along with the movement of tectonic plates, wear down and destroy impact craters.
* Earth's Atmosphere: Our atmosphere acts as a shield, burning up smaller meteors before they reach the surface. Only larger objects can survive the journey and create significant craters.
* Ocean Coverage: Approximately 70% of Earth's surface is covered by oceans. Many impacts likely occur in these areas, leaving no visible evidence.
So, while it might seem uncommon, Earth actually has a rich history of meteorite impacts. We just need to know where to look and understand the processes that erase these scars.
