Question

The smooth-grained version of granite is the rock ___________.



A. andesite
B. coal
C. pumice
D. rhyolite

Answer 1

Rhyolite is a high-silica, fine-grained rock. You cannot see the mineral grains with the naked eye. Its colors are gray, light brown, tan, pale yellow, pink, and other earth-colors. Sometimes there may be a sprinkling of small crystals, but most of the rock is fine-grained. Using food terms, it resembles baloney (unidentifiable components). Rhyolite has the same chemical and mineral content as granite.
