The notion that the Moon is geologically dead has been challenged by new evidence suggesting continued dynamism beneath its surface. Traditionally, the Moon was considered a relic of the solar system’s past, with all volcanic and tectonic activities ceasing billions of years ago. However, several lines of evidence indicate ongoing geological processes.
Firstly, the presence of young volcanic features, known as “lunar swirls,” hint that volcanic activity might have persisted more recently than previously thought. Additionally, data from lunar missions have identified small-scale quakes, known as “moonquakes,” revealing that the Moon is not entirely inert. These quakes may be triggered by tidal forces from Earth or ongoing contraction of the Moon as its interior cools.
Moreover, evidence points to active tectonic processes. Imagery from spacecraft has shown fault scarps across the lunar surface, indicating that sections of the crust are being pushed together, suggesting that the Moon is still shrinking.
Thus, while the Moon might not be as geologically exuberant as Earth, recent evidence indicates it still retains some level of geological activity, challenging the long-held view of the Moon as a dormant celestial body.
