Question

Quizplus · Accepted Answer

The presence of a mass of salt, solidified magma, or volcanic layers/fragments does not specifically support a meteoroid impact origin for Upheaval Dome. Meteoroid impacts are typically identified by features such as a circular structure, shocked minerals, and sometimes a layer of ejecta around the crater, none of which are described in the options provided.
