Abundant water and plate tectonics facilitate these processes on Earth, aiding in remelting.

- Perseverance's Mastcam-Z captures detailed stereo and multispectral images, offering a comprehensive view of the geology in Jezero crater on Mars.
- The rocks depicted show features indicating they are of igneous or impactite origin, with minimal water alteration and include various mineral compositions like mafic silicates and olivine.
- Additional imaging reveals important atmospheric conditions, including dust variations and unique interactions caused by dust devils and the Ingenuity helicopter, which aid in understanding Mars' environment and assist in rover operations.
