Based on what you learn about Jovian moons by watching the videos or reading the textbook, what types of evidence for recent or ongoing geological activity have been observed on one or more jovian moons?

They have an active layer of volcanic crater, and have presence of the tidal heatings.

Explanation:

All the Jovian planets are considered as the gas giants and they have thick ice layers of rocks and these layers have lower temperatures than rocks and allow for the icy volcanism and tectonic activity at lower temperatures. Given the presence of the active crater on the LO, the moon has 400 plus volcanoes, along with more than 100 mountains. Europa has a young creator and tectonic young surface and subsurface oceans within 100 metes of depth. Callisto is heavily created mass of crater and has a thin atmosphere, with icy rocks.
