The Popigai diamonds are small, about 1 mm in size, dark colored, and are used in industrial applications. The immense temperature and pressure caused the humble graphite we know from grammar school pencils to become diamonds. Vredefort crater in South Africa, also called the Vredefort Dome, was originally 185 miles (300 kilometers) across, scientists estimate. The largest known impact craters on Earth include Chicxulub – caused by the asteroid that wiped out the dinosaurs nearly 66 million years ago – which is about 200km (124.3 miles) wide.

Vredefort is located in the Free State province of South Africa and it was apparently produced by one of the largest asteroids ever to hit Earth, a huge rock of 5 to 10 km in diameter, some really long time ago (two billion years). Living things depend on water, but it breaks down DNA and other key molecules. Based on the presence of shocked quartz granules in both the K-Pg Layer and around the Caribbean, scientists concluded that the Chicxulub Crater was formed by an asteroid that crashed into Earth 66,038,000 years ago, plus or minus 11,000 years. The center of the crater is the city of Challis, Idaho. A giant block crashed into the Earth about 2 billion years ago. How the first life on Earth survived its biggest threat — water.

Iridium is rarely found in the Earth's crust because it is heavy and it sank into the Earth's core when the planet was molten. The crater is so large that a whole city fits inside it, which gave its name to the meteor crater. As a tribute to him, the crater was named the Barringer Crater and it is still privately owned by his family. © Here are the 10 biggest impact craters known, from largest to smallest.
