What is much of Everest covered by?

Could you please clarify the context of this question? As it stands, the phrase "What is much of Everest covered by?" seems to be referencing Mount Everest, the world's tallest mountain. However, without additional context, it's difficult to give a precise answer. Assuming you're asking about the natural coverings or features of Mount Everest, I would pose the question in a way that invites elaboration or speculation, such as: "What types of natural elements and features does a significant portion of Mount Everest's surface area seem to be covered by? Are there any particular geological or climatic factors that contribute to its unique appearance?" Keep in mind that Mount Everest, being a towering peak in the Himalayas, is subject to extreme weather conditions and is home to a variety of geological formations, including glaciers, snowfields, and rocky terrain. The specific answer to your question would depend on the season, weather conditions, and the specific area of the mountain being observed.
