Meteor Impact facts

While investigating facts about Meteor Impact Sites and Meteor Impacts On Earth, I found out little known, but curios details like:

A substance called "Libyan Desert Glass"; found in the Eastern Sahara and the deserts of Libya, this glass is of unknown origin (possibly from meteoric impacts), and has been found in ancient Egyptian Jewelry such as Tutankhamun's Pectoral.

how to survive a meteor impact?

The 1833 Leonids meteor shower, the largest one ever recorded estimated at 240 000 "shooting stars" per hour (~67 every second) radiating from Leo constellation over a 9 hour period. The event had such an impact on society that it was used to date people with no birth certificate.

What happens to meteor after impact?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what would a meteor impact be like. Here are 21 of the best facts about Meteor Impact Simulator and Meteor Impact Calculator I managed to collect.

what would a meteor impact look like?

1. The Chesapeake Bay was formed by meteor impact 35 million years ago.

2. Meteorite impact crater "Meteor Crater" in Arizona was named after the nearby post office named Meteor.

3. The Moon is seismically active and has at least 4 different kinds of Moonquakes: Deep moonquakes, Thermal moonquakes, moonquakes caused my meteor impacts, thermal moonquakes, and shallow moonquakes.

4. The thick atmosphere also protects Venus from meteors as they tend to disintegrate before they can pass through to the planet's surface. This means that Venus has fewer crater impacts than on the other inner planets.

5. The asteroid impact that created Meteor Crater in Arizona hit with up to 20 megatons of energy (Hiroshima was 15 kilotons), which sent out catastrophic winds at roughly 900 mph (1,500 km/h). This debris-hurling shock wave would have killed any human-sized animals within about 4 miles (6 km).

6. A meteor the width of 3 or 4 football fields impacted near Calgary, Canada approximately 70 million years ago. It left a crater 6 miles wide, incinerated everything for hundreds of miles, & changed global weather patterns for decades. It is buried so deep that it wasn't discovered until 2009.

7. 600,000 year old Lonar crater lake in India is the only hyper velocity impact crater in the world, it has a mean diameter of 1.2 kilometres (3,900 ft), is about 137 metres (449 ft) below the crater rim, the meteor crater rim is about 1.8 kilometres (5,900 ft) in diameter.

8. There is a substance that appears to be like Jelly and appears after Meteorite impacts or even just meteor showers.

9. The Pacific Ocean had a 74 mile wide hole in it from a meteor impact

10. The period after the dinosaur extinction was "the age of turtles". When 75% of Earth's species perished, 19 species of turtle survived a meteor impact stronger than 1 billion Hiroshima bombs.

Why are meteor impact craters rare on earth?

You can easily fact check why does earth lack small meteor impacts by examining the linked well-known sources.

The impact of a meteor strike created the world's second largest lake island (René-Levasseur Island in Quebec)

Megatsunamis, giant tsunamis which, unlike regular ones, are not caused by tectonic activity but rather by a very large amount of material suddenly falling into water (e.g. a meteor impact). They can have initial wave heights of hundreds or thousands of metres. - source

Over 110 years ago a meteor 100 meters across entered Earth's atmosphere and exploded over Tunguska River in Siberia with the force of multiple Hiroshima bombs. It tore down approximately 80 million trees and to this day nothing grows in the impact zone. - source

The total kinetic energy (before atmosphere impact) of the Chelyabinsk meteor that exploded over Russia in 2013 was 26-33 times as much realeased from the atomic bomb detonated at Hiroshima

Many impact craters have a central dome that is the result of liquefied rocks splashing up in the wake of the meteor strike. - source

When was the last major meteor impact?

The Cumberland Gap was partially formed by a meteor impact over 200 million years ago.

How do meteor impacts affect the earth?

When the Yucatán meteor hit Earth (the one that killed the dinosaurs) the impact was so hard that parts of the planet got blasted into space and landed on Mars.

There are hundreds of detectable lunar impacts from meteors every year, with one in 2013 as bright as the North Star Polaris.
