0 00:00:00,000 --> 00:00:16,000 Minerals do rocks by Benjamin, Martina, Nadia, Lucas and Daniel de Vicente. 1 00:00:16,000 --> 00:00:25,000 Information of minerals. Minerals are inorganic and solid substances that we find on earth. 2 00:00:25,000 --> 00:00:30,000 Minerals can be made from a single element or pure, like gold. 3 00:00:30,000 --> 00:00:35,000 They can also be made of a combination of elements. 4 00:00:35,000 --> 00:00:39,000 All minerals have crystal structure. 5 00:00:39,000 --> 00:00:41,000 Mineral properties. 6 00:00:41,000 --> 00:00:45,000 Color. Minerals have different colors. 7 00:00:45,000 --> 00:00:49,000 For example, quartz can be pink and cobalt is blue. 8 00:00:49,000 --> 00:00:51,000 Crystal structure. 9 00:00:51,000 --> 00:00:54,000 Minerals have different shaped crystals. 10 00:00:54,000 --> 00:00:59,000 For example, sodium crystals and quartz crystals have six sides. 11 00:00:59,000 --> 00:01:03,000 Cluster. Minerals react differently to light. 12 00:01:03,000 --> 00:01:08,000 Some reflect a lot of light and look shiny, like diamond or gold. 13 00:01:08,000 --> 00:01:13,000 Others reflect less light and look dull, such as graphite. 14 00:01:13,000 --> 00:01:20,000 Hardness. The hardness of a mineral consists on its resistance to scratching. 15 00:01:20,000 --> 00:01:24,000 We can scratch the mineral with other minerals. 16 00:01:24,000 --> 00:01:27,000 Kind or point of objects. 17 00:01:27,000 --> 00:01:31,000 Minerals can be soft, hard or very hard. 18 00:01:31,000 --> 00:01:33,000 Examples of minerals. 19 00:01:33,000 --> 00:01:35,000 Diamond. Square, shiny and very hard. 20 00:01:35,000 --> 00:01:39,000 This is the most expensive and weirdest diamond of the world. 21 00:01:39,000 --> 00:01:41,000 The name of this diamond is enigma. 22 00:01:41,000 --> 00:01:43,000 Cobalt. Flat and shiny. 23 00:01:43,000 --> 00:01:46,000 It has six sides, shiny and hard. 24 00:01:46,000 --> 00:01:48,000 Gold. Square, shiny and hard. 25 00:01:49,000 --> 00:01:50,000 Information of rocks. 26 00:01:50,000 --> 00:01:54,000 Sedimentary rocks. Sedimentary rocks are rocks made from sediments. 27 00:01:54,000 --> 00:01:57,000 Sediments are thin layers of rocks. 28 00:01:57,000 --> 00:02:03,000 Sand, shales and remains of living things that were deposited over time. 29 00:02:03,000 --> 00:02:10,000 Over time, a very long time, these sediments get compacted into what forms a rock. 30 00:02:10,000 --> 00:02:15,000 Sometimes these sedimentary rocks have fossils of animals or plants. 31 00:02:15,000 --> 00:02:17,000 Metamorphic rocks. 32 00:02:17,000 --> 00:02:25,000 Metamorphic rocks are ingenious or sedimentary rocks due to heat, pressure or friction. 33 00:02:25,000 --> 00:02:28,000 These rocks turn into metamorphic rocks. 34 00:02:28,000 --> 00:02:36,000 Marble is a metamorphic rock that is formed when limestone changes due to heat or pressure. 35 00:02:36,000 --> 00:02:40,000 Slate is also a metamorphic rock. 36 00:02:40,000 --> 00:02:42,000 Igneous rocks. 37 00:02:42,000 --> 00:02:46,000 Igneous rocks are formed from the solidification of solid magma. 38 00:02:46,000 --> 00:02:53,000 Magma is a liquid, very hot rock that we can sink deep inside the earth's crust. 39 00:02:53,000 --> 00:03:04,000 The magma can cool down inside the earth's crust and form an igneous rock such as the granite. 40 00:03:04,000 --> 00:03:10,000 This magma can also go up the surface in a volcanic eruption. 41 00:03:10,000 --> 00:03:12,000 This is called a lava. 42 00:03:13,000 --> 00:03:19,000 When the lava flows, it forms an igneous rock such as the basalt. 43 00:03:19,000 --> 00:03:23,000 Plaster is soft and shimmy. 44 00:03:23,000 --> 00:03:27,000 Limestone is resistant and hard. 45 00:03:27,000 --> 00:03:30,000 Granite is heat-resistant. 46 00:03:30,000 --> 00:03:35,000 Grave is hard and it has gravity. 47 00:03:35,000 --> 00:03:36,000 Difference. 48 00:03:36,000 --> 00:03:45,000 A mineral is a natural solid with a characteristic crystal shape and rocks are made of mineral spices mixed together. 49 00:03:45,000 --> 00:03:52,000 Most minerals can be characterized and classified by their unique physical properties. 50 00:03:52,000 --> 00:03:58,000 However, rocks form, break down and move throughout the rock cycle. 51 00:04:00,000 --> 00:04:02,000 What is this mineral? 52 00:04:02,000 --> 00:04:04,000 Diamond or Coal? 53 00:04:04,000 --> 00:04:08,000 If you say diamond, it's correct. 54 00:04:08,000 --> 00:04:13,000 What mineral is not solid? Gold or Cobalt? 55 00:04:13,000 --> 00:04:18,000 If you say cobalt, it's not correct. It's gold. 56 00:04:18,000 --> 00:04:21,000 Thanks for listening!
