  • Understanding Earth's Impact Craters: Why Aren't There More?
    It's actually not true that craters from meteorites are uncommon on Earth. We have discovered thousands of impact craters on our planet! The reason we don't see them everywhere is due to a few factors:

    * 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.
