Graphite is a grayish-metalicish rock that leaves a dark gray streak, kind of like lead. often black.
Graphite is just an allotrope of the element carbon, in that it is carbon in a different form. Graphite exists in a hexagonal planar structure which allows sheets of graphite to slide over each other easily which is what you see when you write; it is also used as a lubricant (though not in a vacuum) The allotropes of Carbon include diamond, graphite and fullerenes.
The color of a powdered sample of a rock is called its streak. Streak is determined by rubbing the sample across a rough white ceramic plate to reveal the color of the mineral's powder.
China is the largest producer of clay, accounting for a significant portion of the global production. For graphite, China is also a major producer, alongside countries like India and Brazil.
The most abundant resources of North Korea include coal, iron ore, limestone, magnesite, and graphite. These resources play a significant role in North Korea's economy and industrial production.
It takes multiple countries to make a pencil. For example, the wood may come from one country, the graphite from another, and the metal ferrule may come from yet another country. The components are then assembled in another location before the pencil is distributed globally.
Graphite is a mineral that does not leave a clear streak.
i have no idea..... but its probably a no .. take my advice.
The same color as the writing from a pencil, very dark grey or black. Pencils used to be made of graphite
Graphite is a soft, black mineral that leaves a streak on paper and is used in pencils. Galena is a lead-gray mineral that is heavy and often forms cube-shaped crystals. One way to distinguish them is by conducting a streak test - graphite will leave a black streak, while galena will leave a gray streak.

The mineral that fits this description is graphite. Graphite is very soft and can be easily scratched by a fingernail. It has a metallic luster and a black streak.
Graphite leaves a streak on paper, as it is the material commonly found in pencils. The black mark left on paper is due to the graphite particles rubbing off onto the surface.
well i really don't know sorry. Here are some useful things close to that... 1. Mica shows clear cleavage. 2. Hardness is a measure of how easily a mineral can be scratched. ill tell you as soon as possible when i figure it out! Thank you
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.
Gypsum Hematite Magnetite Pyrite Galena Bornite Chalcopyrite Graphite Cinnabar Sphalerite
White, but i have no idea why or how, it is used in white pencils replacing graphite and is used to write on black paper
The streak test is not a very good identifier of rocks because rocks are composed of combinations of minerals which may have different color streaks. The streak test is mainly used in mineral identification. Even then, it is used in common with other indicators, like hardness, crystal system, and chemical composition.
