The answer is: Earthy luster.

Explanation:

  • An earthy luster is characteristic of minerals that appear dry and chalky. This type of luster is typically dull and non-reflective, resembling the appearance of soil or clay.
  • Other types of luster, such as metallic, vitreous, or pearly, do not fit the description of a dry and chalky appearance. Metallic luster is shiny and reflective like metal, vitreous luster is glass-like, and pearly luster has an iridescent sheen similar to a pearl.
  • Therefore, the correct description for a mineral that looks dry and chalky is that it has an earthy luster.
