Earth has craters just like the Moon! Here is what NASA says

Our planet Earth too has craters on its surface. Here is what NASA has informed about the same.

Other than the Moon and our Solar System, Earth too has been hit by several asteroids and other objects creating craters on its surface. But it needs to be noted that not every object heading towards Earth reaches its ground mainly because of the atmospheric layers. Here are some of the biggest craters impact that dented the surface of the Earth. (Google Earth)

What is an impact crater? According to the information provided by Space Place, NASA, "An impact crater is formed when an object like an asteroid or meteorite crashes into the surface of a larger solid object like a planet or a moon. To form a true impact crater, this object needs to be traveling extremely fast—many thousands of miles per hour! When a solid object crashes into something at these super fast speeds, it forms a crater regardless of how hard or tough it is." (Pixabay)

Evidence of really big impacts – such as Arizona’s Meteor Crater – is harder to find on Earth. The impact history of our home world has largely been erased by weather and water or buried under lava, rock, or ice. Nonetheless, we still find new giant craters occasionally, NASA said. In 2019, a NASA glaciologist discovered a possible impact crater buried under more than a mile of ice in northwest Greenland. That followed the finding, announced in November 2018, of a 19-mile-wide crater beneath Hiawatha Glacier – the first meteorite impact crater ever discovered under Earth’s ice sheets. Though these impact sites in northwest Greenland are only 114 miles apart, at present they do not appear to have formed at the same time. (Pixabay)

Meteor Crater (also known as Barringer Crater) in Arizona was the first crater discovered to be formed by an extraterrestrial impact. It formed 50,000 years ago from a meteorite that may have been up to about 150 feet wide traveling more than 28,000 mph, according to the information provided by NASA.

Vredefort crater in South Africa is the largest known impact crater on Earth—almost 200 miles across. At over 2 billion years old, it is also one of the oldest. Because of erosion over this long time period, the crater is a bit difficult to see. (NASA)
