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