Scientists have discovered 170 craters on Earth, but some of them are truly stunning. One example is the Pingualuit Crater in Canada, which helped researchers learn about climate change during the Ice Age. Another is the Wolfe Creek Crater in Australia, which is significant to the Djaru Aboriginal people. The Barringer Crater in Arizona is a mile-wide reminder of a massive asteroid impact, while the Nördlinger Ries crater in Germany is a unique rampart crater. Other notable craters include Tenoumer Crater in Mauritania, Lonar Crater in India, Tswaing Crater in South Africa, and Gosses Bluff in Australia.
