rocks and minerals
Transcript of rocks and minerals
By Zachary T. Im doing my prezi on rocks and minerals hope you enjoy!!!=) This type of rock is called Amithist. Amithist is usually the color purple. This type of rock is called garnet.=) Garnet can come in multiple diffrent colors like for example, red, green, blue, and even orange!!!=) Did you know that amethest is a stone traditionally worn to guard against drunkeness and to instill a sober mind. The word amethyst comes from the Greek meaning "without drunkenness" and amethyst is believed to protect one from poison. This type of rock is called orange quartz.
It is a cool orange color.!!!=) This type of rock is both cystal and amethist.!!!=) This type of rock is called pyrites fools gold. It is one of my favrite types of rocks. There are many different types of pyrite. Including this iron pyrite picture. Can you guess what special thing this is? If you look closely this is actually a special iron pyrite pyrimid found in the ground. You can find rocks and minerals as little as 1 feet underground. And sometimes you can even find them above ground. This is the cicle of rocks and minerals. Yes pretty much all of the minerals in the world are hard. Mineral lonsdaleite is the hardest meterial in the world.
It can withstand 58% more pressure then diamonds themselves!!! And is however extremely more rare to find then diamond itself. A 2.33 carat diamond is worth about $56647.13 so a
lb would be about $56,647,130! One pound of gold is worth $16,310.37 today. Gold is measured in Troy ounces.
If gold is 1096.00 per ounce how much is a pound worth? 16 x 1096 =$17536 The Cullinan diamond is the largest rough gem-quality diamond ever found, at 3,106.75 carats (621.35 g). The quantity and quality of light reflected from the surface. Most identification schemes begin with a simple classification based on luster. Because of this, luster is the first fundamental test to be made when identifying any mineral. Most are relatively obvious, but some minerals can exhibit a range of lusters (ex. Hematite). The mose hardness scale is a thing were it tells people on a base of 1-10 how hard is a rock or a mineral The earth is actually a dynamic and ever-changing planet. Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth’s plates slowly reconfigures oceans and continents. Few people have changed the world with the power of an idea. Charles Darwin, the British naturalist who lived during the 1800s, was one of them. While we might equate the idea of evolution with other revolutionary scientific breakthroughs, such as Einstein's general theory of relativity, people seem to care less about what it means
to live in a universe where the speed of light is fixed than in a world in which humans descended from hairy apes. That is a tricky question because of its implications about the very nature of life, humanity, and religion. It is the reason why some greet Darwin’s name with a gut-level sense of distrust even though his contributions to our understanding of life are as solidly confirmed as are Einstein’s contributions to our understanding of the universe. So, it is no surprise that more people have an inkling - too often wrong - of what is meant by Darwin's concept of natural selection than by the terms of Einstein's famous equation E = mc2.
Gravity is the physical force of attraction between any two objects in the universe. One of the four fundamental forces (the others are electromagnetism and the strong and weak forces), gravity affects all objects on Earth. From the largest mountains to the smallest grains of sand, gravity pulls everything in a direction toward the center of the planet. As long as material remains on a flat surface, one that is parallel to Earth's surface, gravity will not cause it to move. When material is on a slope and conditions are right, however, gravity will cause it to fall, slide, flow, slump, or creep downward.
