“Over millions of years, material from this ring gradually fell to Earth, creating the spike in meteorite impacts observed in the geological record... We also see that layers in sedimentary rocks from this period contain extraordinary amounts of meteorite debris,” said lead study author Andy Tomkins in a statement.

When earthquake energy is sent into these sedimentary basins, it amplifies the intensity of the shaking — perhaps 10 times worse than if someone were on bedrock — and also causes shaking to resonate like a bowl of Jell-O, extending the duration.

He and his family live in Colorado on top of a geological feature known as the Morrison Formation, a stretch of sedimentary rock dating back to the Jurassic period which covers 600,000 square miles of the western United States.

Perseverance was then to leave Ingenuity behind and begin studying ancient sedimentary rocks along the rim of Jezero crater, which held a lake of water several billion years ago.

They noticed there was a clear sedimentary change from pre-earthquake lagoon silt to post-earthquake rooted soil.
