supported rivers and lakes over a time span of more than a billion years. But, like Earth …

This revised and updated edition continues to provide a comprehensive introduction to the
subject, exploring the world's landforms from a broad systems perspective. It covers the …

Mars exhibits diverse surface changes at all latitudes and all seasons. Active processes
include impact cratering, aeolian sand and dust transport, a variety of slope processes …

The rate of occurrence of High Frequency (HF) marsquakes, as recorded by InSight at
Homestead Hollow, Elysium Planitia, increased after about LS= 33∘, and ceased almost …

Due to its significance in astrobiology, assessing the amount and state of liquid water
present on Mars today has become one of the drivers of its exploration. Subglacial water …

Many discoveries of active surface processes on Mars have been made due to the
availability of repeat high-resolution images from the High Resolution Imaging Science …

Fan-shaped sedimentary landforms on Mars are important geomorphic markers of past
water flow and characterizing the distribution and morphology of these features can yield …

The formation process for Martian gullies is a critical unknown for understanding recent
climate conditions. Leading hypotheses include formation by snowmelt in a past climate, or …

The mid-to high latitudes of Mars host assemblages of landforms consistent with a receding
glacial landscape on Earth. These landforms are postulated to have formed> 5 Ma under a …

Carbon dioxide is Mars' most active volatile. The seasonal and diurnal processes of when
