B) 5.92 k 10^14 Hz.
C) 1.02x10^14 Hz.
D) 3.53 k 10^14 Hz.
E) 2.05 k 10^14 Hz.

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
