Understanding Vallis Formations Across Our Solar System

Vallis is a Latin word that means "valley". In geology, a vallis is a long, narrow depression or valley that is found on the surface of a planet or moon. These features are often formed by tectonic activity, such as faulting or subsidence, and can be filled with sediment or lava. Valles can be found on many celestial bodies in our solar system, including Mars, Venus, and the Moon.
