An example of simile in popular science writing:
"Meteorites that are suspected to have been knocked off Mars bring with them Martian atmospheric gases they trapped within their rock structure when they formed. When these samples are cracked open in laboratories on Earth, the gases trapped inside can be measured and their composition and abundance compared with the measurements made in space – like a sort of 'fingerprinting'."
