The Crater on Mercury That Defied Conventional Models: MESSENGER Images part 2

The video explores Mercury's volcanic past, highlighting its extreme temperatures and geological changes. It discusses how craters and valleys provide evidence of past lava flows and volcanic activity. The video also explains the formation of volcanic ash and the impact of meteors on Mercury's surface. Despite its violent past, Mercury is now geologically quiet, with no active volcanoes.

What are the two theories regarding the source of lava in craters on Mercury?

How did volcanic activity contribute to the surface features observed on Mercury today?

Discuss the implications of volcanic ash found on Mercury's surface.
