The mineral graphite is soft enough to leave a mark on paper. We use graphite, which is a form of carbon, as pencil lead. And it works pretty darn well at leaving marks on paper.

What are non examples of streak?

Non-examples of a streak, in the context of geology, mineralogy, and everyday life, are situations or substances where the concept of a streak doesn't apply. A streak, in geology, refers to the color of the powder left behind when a mineral is scraped against an unglazed porcelain plate (streak plate). Here are some non-examples of streak: **Transparent Materials:** Transparent materials, such as glass or clear plastic, do not exhibit a streak. When these materials are scraped against a streak plate, they do not leave a visible colored powder or mark. **Liquids:** Liquids, by their nature, do not produce streaks when applied to a streak plate. They flow and do not leave a powder or solid residue. **Gases:** Gases, being in a gaseous state, do not produce streaks. They are not capable of leaving any visible mark on a surface. **Non-Powdered Substances:** Substances that are not in a powdered or solid form do not have streaks. Streaks are primarily associated with powdered materials. **Organic Materials:** Organic materials like wood, paper, or food do not exhibit streaks. When these materials are rubbed on a streak plate, they typically do not produce a discernible streak. **Unsaturated Solutions:** Unsaturated solutions (those in which a solute has not reached its maximum possible concentration) will not produce a streak when applied to a streak plate. Streaks are typically associated with solid materials. Streak is a property primarily used to identify minerals based on the color of the powdered residue they leave behind, and it is not applicable to substances or situations where no such residue is produced.
