1. Chicxulub Crater, Mexico
The Chicxulub impact is widely believed to have led to the extinction of dinosaurs, because of a global firestorm or because of a dramatic and widespread greenhouse effect that caused long-term environmental changes.

2. Manicouagan Crater, Canada
Some 212 million years ago, a 3 mile (5km) wide asteroid hit the earth, to causing a 62 mile (100km) wide giant hole. It has been worn away by the passing of glaciers and other erosive processes, ever since.
3. Kara-Kul Lake, Tajikistan
The lake is actually located within a 28 mile (45km) wide circular depression, which was hit by a meteorite approximately 5 million years ago. Kara-kul was only discovered recently, through satellite imagery.
4. Clearwater Lakes, Canada
Two circular lakes/impact craters on the Canadian Shield in Quebec formed simultaneously by the impact of an asteroid pair which crashed on Earth approximately 290 million years ago, near the eastern shore of Hudson Bay. The larger of the two craters is West Clearwater Lake with a 20 mile (32km) diameter, while the smaller one, East Clearwater Lake, has a 13.7 mile (22km) diameter.
The lakes are a great tourist location mostly because of the number of sprinkling islands that form a sort of a “dotted line”. The lakes are also, obviously, famous for their clear waters.
5. Mistastin Lake, Canada
6. Gosses Bluff, Australia
7. Aorounga Impact Crater, Chad
The crater is about 11 miles (17 km) across and is accompanied by two nearby circular features that have been revealed by the Space Shuttle's SIR-C radar after picturing an area of about 22 miles (36 km). If the assumptions and the hypothesis that the dark band in the upper right corner could be a second impact crater, then Aorounga may be part of a chain of multiple impact craters.
8. Deep Bay, Canada
9. Lake Bosumtwi Crater, Ghana
10. Barringer Crater, Arizona, US
It measures 0.75 miles (1.2 km) across, is 575 ft (175 m) deep and has a rim 148 ft (45 m) higher than the surrounding plain. Discovered in 1902, the Barringer Crater was named after Daniel Barringer, a successful mining engineer. Today it is still owned by his family and is also known as Meteor Crater, Coon Butte, and Canyon Diablo.
