MATALLIC MENIRALS ROLL NO: 07 Metallic Minerals On an auspicious day‚ sometime around a million years ago‚ a member of the Homo habilis species stood erect and walked steadily on his two feet and his two hands became totally free. A new species – Homo erectus—began its journey on a new evolutionary track. This great change took around four million years after his ancestors – the hominids — broke free from the lineage of apes and chimpanzees. But ‚ perhaps for the next seven to eight hundred

Minerals are elements that originate in the Earth and cannot be made by living organisms. They are natural compounds formed through geological processes and are what remains as ash when plant or animal tissue is burned or decompose completely after death. Minerals are inorganic substances which means they are not formed by living matter and contain no carbon‚ and can be simply defined as chemical molecules which cannot be reduced to simpler substances. To be classified as a "true" mineral‚ a substance

A mineral is any naturally occurring‚ inorganic substance‚ often additionally characterized by an exact crystal structure. Its chemical structure can be exact‚ or can vary within limits. Minerals possess a number of properties that are used as an aid in their identification just like color‚ luster‚ streak‚ cleavage‚ hardness‚ specific gravity‚ and even by their chemical properties‚ composition‚ Hardness‚ Crystal Form‚ Electrical Properties and Melting Points. Here I got a mineral as shown in the

All minerals have four properties: 1. All minerals are naturally occurring 2. All minerals are inorganic (that means non-living) 3. A different chemical formula can be written for each mineral and that formula is constant for that mineral. ex. Galena is PbS- that is it has one lead atom (Pb) and one sulfur (S) atom in each molecule. 4. Most minerals have an unique crystalline shape given the right growing conditions (like in a cave). Compounds are substances that has two or

A mineral is a naturally occurring substance that is solid and stable at room temperature‚ representable by a chemical formula‚ usually abiogenic‚ and has an ordered atomic structure. It is different from a rock‚ which can be an aggregate of minerals or non-minerals

Rocks and minerals are all around us. Earth’s crust and part of its mantle are made of rock. Rocks are made of minerals and have different properties. The properties of rocks include color‚ texture‚ luster‚ and hardness. We use rocks and minerals in many different ways. The steel in our buildings is made with iron‚ which is a mineral. The clay and glass used in our pottery and dishes are made of a mixture of rocks and minerals. We even need minerals to stay healthy‚ and we get them from a variety
