The Oldest Crater from a Meteorite…Isn’t a Crater after All?

The video explores the history of impact craters on Earth and the Moon, focusing on the Maniitsoq structure in Greenland. Initially thought to be the oldest impact crater, new research using zircon crystals suggests it may result from tectonic and volcanic activity. The debate continues as scientists seek to understand the structure's origins and implications for Earth's history.

Why is the Maniitsoq structure significant in understanding Earth's early history?

What geological processes were suggested to explain the features of the Maniitsoq structure if not an impact?

What challenges do scientists face in explaining the pulverized rocks at the center of the Maniitsoq structure?
