A) True
B) False

Answer 1

True. The color and shape of quartz can vary, requiring geologists to examine other physical properties for proper identification.

Step-by-step explanation:

True

The statement is true. The color and shape of quartz can vary from sample to sample, making it necessary for geologists to examine other physical properties to properly identify the mineral. The color of minerals is influenced by small impurities in their chemical composition, and elements can substitute for one another, leading to variations in color. Quartz, for example, can come in a wide range of colors.
