    Do you go to school on a bike, car, or bus? Titanium is a mineral that is used to make bikes, since it is light and strong. Metal is a mineral used to make cars and buses, because metals are strong and useful. Minerals are everywhere and they help us make our lives easier and more enjoyable.
    There are many kinds of minerals. Titanium is one of the minerals that make up a rock. There are three kinds of rocks. Igneous rocks, metamorphic rocks, and sedimentary rocks. Many kinds of minerals make up these three main kinds of rocks.

    Minerals From Solutions
    By Mayli Yang & Lennan Sarathchandra {Benitoitel.jpg} Benitoitel Minerals can be formed from solutions, in two different methods. One of the methods is when water evaporates as in a dry climate from a solution and leaves behind ions which later come together to form crystals. The other method can be formed when there are too much substance dissolved in water, and ions will eventually come together to form crystals in that solution. Using this process you would not need evaporation. Both of these techniques are very similar and also different in many ways.

    A mineral is a solid inorganic substance which has a definite chemical composition formed inside blocks of rocks. The atoms inside the mineral are arranged in an orderly pattern. There are three main ways in which minerals can be formed, and all minerals are fromed naturally. One way is when magma cools down, and the minerals are formed with a definite crystal pattern. The other method in which minerals are formed is when water from a mineral solution evaporates and leaves behind the crystals. The last technique is when minerals precipitate out of the water. These processes of mineral formation are called crystallization.

    By Lennan Sarathchandra One way they form is by magma. When magma reaches earth surface or is even trapped below it, magma {Zoisite.jpg} ZOISITEcools, it turns into silicate rock. Atoms will then lose heat energy, moving closer together and begin to combine into compounds. During this process atoms of the different compound will start to arrange themselves into orderly repeating patterns. Each different eruption of the volcano, which comes to the earth is made of slightly different chemicals, which leads to different rocks. The type and amount of elements present in magma will determine which minerals will form. The speed that the magma cools will determine the size of the mineral. If it forms for a long period of time, the crystals will be large enough for a human eye to see. This is because atoms have a good amount of time to combine and form into a large crystal enough for you to see. But when magma cools down rapidly, you’ll have a disadvantage since you won’t be able to see, and this is due to the rapid speed of the magma’s cooling down.

    The second method of minerals forming form solutions is quite similar to the first. For this method, you have to heat up you water and have it saturated. Then you let it cool down. According to the theory, hot water holds more substances than cold air. Since the solution is saturated while the water is hot, it could hold a lot more substances. As the water cool down, the minerals precipitate out of the solution, for the space within the water is restricted. As the minerals precipitate out, they arranged themselves in an orderly pattern of atoms.

    Basaltic igneous rocks form from magma that is rich in iron and magnesium, and poor in silica. The iron and magnesium give it the dark color. They are dense, and dark colored. Basaltic lava is fluid, and flows freely from volcanoes,especially in Hawaii. Basalt forms on the surface of the Earth, it is an extrusive rock.
