Peak ring (crater)

Imagine you have a big ball of playdough and you drop it on the ground really hard. The playdough will squish down and create a big dent in the ground. This dent is called a crater.

When a really big object like a meteorite crashes into the ground, it can create a much bigger crater. The meteorite hits the ground with such force that it causes a huge explosion, sending shockwaves through the surrounding area. These shockwaves create an inner part of the crater called the peak ring.

The peak ring is a circular ridge that surrounds the center of the crater. It's made up of rocks that were once deep beneath the surface of the ground, but were pushed up and out by the shockwaves from the meteorite impact. These rocks are different from the rocks on the surface and can tell scientists a lot about the history of the planet.

It's kind of like when you push your finger into a ball of playdough and it makes a ridge around your finger when you pull it out. The meteorite impact is like your finger pushing into the playdough and the ridge is like the peak ring.
