Venus Coronae
The feature of Venus' geography called a "Corona" is a deep, curving, trench surrounding an elevated plain. Coronae is the plural term for corona.
This is an image of Artemis Corona which is found on Aphrodite Terra, and is the largest of the coronae.
This coronae shows a nearly circular trench, called Artemis Chasma, which has a diameter of over 1250 mi.
Based on the similarity of the shape of the trench to the shapes of island arcs (near subduction zones) on Earth, coronae may provide evidence that the planet's surface is in motion.
