Venus Shows Signs of Recent Geological Activity
Scientists have discovered that Venus, which was thought to be geologically inactive, might actually be quite active.
Recent studies using advanced computer models show that large rifts on Venus's surface, which can be up to 10,000 kilometers long, might be very young.
This suggests that the planet's crust is still stretching and breaking apart, meaning that Venus's insides are still active.
The rifts were likely caused by hot rock rising from deep inside the planet.
This new information helps us better understand the geology of Venus and shows that it is not a 'dead' planet as previously thought.
Venus's large rifts, up to 10,000 kilometers long, suggest recent geological activity.
A study by ETH Zurich researchers used a 3D computer model to analyze Venus's crust.
The rifts studied are Ganis Chasma, Dali Chasma, and Davana Chasma.
The crust is moving apart at a speed of 3 – 10 cm per year.
The rifts were likely caused by mantle plumes or columns of hot rock rising from deep inside Venus.

Venus is Geologically Active
Recent studies and images suggest that Venus's crust is still stretching and breaking apart, indicating geological activity.
Venus is Geologically Inactive
Previous assumptions and some scientists believe Venus is a 'dead' planet with no recent geological activity.
