The largest meteorites leave enormous holes in the ground called impact craters. The best-preserved impact crater in the world is the Barringer Meteorite Crater, near Winslow, Arizona. There, more than 50,000 years ago, a meteorite weighing about 270,000 metric tons (300,000 tons) slammed into the Earth with the force of 2.5 million tons of TNT. It was discovered to be 82% iron and 16% nickel. That makes it a rarity among meteorites, as only about 6% of meteorites are primarily iron. Most impressively, it weighs around 50 tons, making it the biggest intact meteorite on the planet. And yet it left virtually no crater when it slammed into the earth. How is this possible? Kentland crater. Deformation involving bending and overturning is evident in the layered limestones exposed by quarrying at the Kentland impact structure. The Kentland structure, also known as the Kentland crater or the Kentland disturbed area, is an impact structure located near the town of Kentland in Newton County, Indiana, United States. [1] The largest known stony-iron meteorites are two fragments of the Brenham meteorite found near Haviland, Kansas (and which are possibly associated with an impact crater near there); these have masses of 650 kg and 450 kg. The largest stony meteorite known is apparently a 654-kg fragment of the Chelyabinsk meteorite that fell near Chelyabinsk The Deniliquin structure, shown in red, could be the largest asteroid crater in the world. killing up to 85 per cent of Earth's species at the time. Andrew Glikson, from the University of New March 24, 2015. An artist's rendition of an asteroid impact. Mike Agliolo/Corbis. Back in 2013, scientists conducting geothermal drilling in the south Australian outback came across something am0Jsp1. 3 – Vredefort Crater, South Africa (118 Mile Diameter) Wiki Info: The Vredefort crater is the largest verified impact crater on Earth, more than 300 km across when it was formed. What remains of it is located in the present-day Free State Province of South Africa and named after the town of Vredefort, which is situated near its centre. The Cretaceous–Paleogene ( K–Pg) extinction event, [a] also known as the Cretaceous–Tertiary (K–T) extinction, [b] was a sudden mass extinction of three-quarters of the plant and animal species on Earth, [2] [3] approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs. The Yilan Crater is the largest meteorite impact crater on Earth in 100,000 years, reported Xinhua News Agency. The article noted that the crater was exposed in the Early Jurassic granite of the With a diameter of just 66 feet, the Chelyabinsk meteor was the largest object to enter Earth's atmosphere from space since 1908, 9 km diameter crater 0.6 km deep Meteor Crater in Arizona (formally called Barringer meteorite crater) viewed from the rim near the visitor center. The crater is nearly a mile across and the hole more than 550 feet deep. (Image There are several reasons for this. First, meteorites slow down or even burn out in our atmosphere before they can reach the surface. Second, 70% of Earth is covered with water—we can only see
