Martian geology is the study of the geology of the planet Mars. Scientists who study Martian geology investigate the planet's surface features, rock formations, geological processes, and history of geological evolution. They are interested in understanding the planet's past climate, water history, tectonic activity, and the potential for past or present life on Mars. Martian geology research often involves the analysis of data collected by spacecraft, rovers, and landers on Mars, as well as laboratory studies of Martian meteorites that have landed on Earth. By studying the geology of Mars, scientists are able to better understand the planet's geological history and its potential for past or present habitability.
