What are the fragments that come out of the Yellowstone supervolcano?

The fragments that erupt from the Yellowstone supervolcano primarily include volcanic ash, pumice, and lava. During explosive eruptions, fine ash can be ejected high into the atmosphere, while larger pumice fragments and volcanic rocks may fall closer to the vent. These materials can spread over vast areas, impacting the environment and climate. The most significant eruptions in Yellowstone's history have produced extensive layers of these volcanic deposits.
