Meteorite strike in South Africa: scientists offer clues about what it is and where it came from Original
On a Sunday morning in late August 2024 a nine-year-old girl named Eli-zé du Toit was sitting on her grandparents’ porch near a small town in South Africa’s Eastern Cape province, when she heard a long rumble, then heard a rustling in a nearby fig tree. As she watched, a rock fell out of the tree. When Eli-zé picked it up, she noticed that the rock had a black crust and a grey interior “like concrete”. It was warm on the crust and cold on the inside.

THE CONVERSATION: Curious Kids: Why are there so few impact craters on Earth?
Scientists call these “impact craters”: a bowl-shaped depression in the rocky crust of a planet, moon or asteroid that is caused by another rocky piece of space debris slamming into it really fast. This high-speed collision – over 36,000 kilometres per hour! – releases a huge amount of energy that causes a lot of destruction. I am a geoscientist who studies impact sites in Africa and on other continents. Scientists like me have identified the remains of around 200 impact craters across our planet.
Curious Kids: Why are there so few impact craters on Earth?
