You can identify minerals by color‚ streak‚ luster‚ hardness‚ cleavage‚ and fracture. Minerals form by magma erupting and forming lava then cooling. They can also form by evaporation of water containing dissolved ions. Silicates are the most common group of minerals found in the earth’s crust. The structure of minerals are orderly. They form crystalline. A crystalline has flat faces and smooth surfaces. Igneous rocks are formed from magma. If they are intrusive (plutonic)‚ they have large

Elements‚ Mixtures and Compounds An element is a pure substance made of one type of particle (atom). Particles can join up with other particles of the same type to form molecules. Examples: Hydrogen = H2 . This means there are two atoms of hydrogen joined together to form a molecule of hydrogen gas. Oxygen = O2‚ Nitrogen is H2‚ Chlorine is Cl2. A compound is a pure substance of two or more elements chemically combined together in a set ratio. Example: Water = H20 this means there are always

The atmosphere is practically everything above the Earths surface. It starts at ground level and then just goes on upward‚ getting thinner and colder until it finally dissolves into space. The atmosphere makes our world livable. It is responsible for winds‚ weather‚ temperature and a lot more features that make the Earth different than other planets. Without it‚ the Earth would be more like the moon. From a general point of view‚ the atmospheres composition seems simple. It contains oxygen produced
