sure! here are three questions related to the article:\n1. what physical property of a rock helps determine how it reflects light, and what are two common types of this property?\n2. why might color alone not be a reliable indicator when identifying a rock?

Answer

Brief Explanations:

  1. The physical property is luster. Two common types are metallic and non - metallic luster. Luster describes the way a mineral or rock reflects light. Metallic luster gives a shiny, metal - like appearance, while non - metallic luster can be described as vitreous (glassy), resinous, etc.
  2. Color alone is not reliable for rock identification because impurities can change a rock's color. Also, different minerals can have the same color, and the same mineral can have different colors depending on factors like oxidation state or the presence of trace elements.

Answer:

  1. The physical property is luster. Two common types are metallic luster and non - metallic luster.
  2. Because impurities can change color, different minerals can have the same color, and the same mineral can have different colors due to factors like oxidation state or trace elements.
