    Understanding Moon’s Valleys and Rilles

    Definition of Valleys and Rilles

    Valleys and rilles are geological features found on the surface of the Moon. Valleys are long, narrow depressions that can stretch for hundreds of kilometers. They are typically formed through the collapse of lava-filled underground tunnels or due to tectonic activity. Rilles, on the other hand, are narrow channels or grooves that are believed to have been formed by the flow of lava or by the collapse of subsurface structures.

    Formation of Valleys and Rilles

    The formation of valleys and rilles on the Moon is primarily attributed to volcanic activity and tectonic movements. The Moon was once geologically active, with volcanic eruptions and the movement of tectonic plates shaping its surface. During volcanic activity, magma would flow and fill underground tunnels, forming lava tubes. Over time, these tubes could collapse, creating the long, narrow valleys that we observe today. Tectonic activity, similar to what occurs on Earth, can also lead to the formation of valleys and rilles.
