Coal forms naturally from the remains of plants that are squeezed tighly together. ]]> 2017-10-19 20:27:18 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/198867499 Solid marias8 https://padlet.com/marias8/5mfa1jj5cy56/wish/198868156 A mineral is always solid and has a definite volume and shape. Both Coal and Quartz are solids]]> 2017-10-19 20:30:10 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/198868156 Crystal structure marias8 https://padlet.com/marias8/5mfa1jj5cy56/wish/198868209 A mineral´s particles line up in a pattern that repeats over and over again. This repeating pattern forms a solid called crystal. 
A crystal has flat sides, called faces that met at sharp edges and corners. 
While Quartz has a crystal structure , most coal lacks a crystal structure. ]]> 2017-10-19 20:30:23 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/198868209 A mineral is a naturally occuring solid that can form by inorganix processes and that has a crystal structure and a definite quemical composition. For a substance to be a mineral it must have all 5 of these characteristics, so it´s a quartz or a coal mineral. marias8 https://padlet.com/marias8/5mfa1jj5cy56/wish/198868765 2017-10-19 20:32:16 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/198868765 Forms by Inorganic Processes marias8 https://padlet.com/marias8/5mfa1jj5cy56/wish/198870113 Every mineral must be able to form from materials that were not part of a living thing. But, Coal comes only from living things(The remains of plants that lived thousands of years ago). ]]> 2017-10-19 20:36:35 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/198870113 Definite Chemical disposition marias8 https://padlet.com/marias8/5mfa1jj5cy56/wish/198870744 Every mineral always contains certain elements in defintie proportions. An element is a substance composed of a single kind of atom. 
Quartz always contains 1 atom of silicon for every 2 atoms of oxigen. ]]> 2017-10-19 20:39:18 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/198870744 Hardness jalvarez17 https://padlet.com/marias8/5mfa1jj5cy56/wish/199597485 The Mohs harness scale is used to rank the hardness a ranking from 1 to 10 hardness can be determine by a scratch test. A mineral can scratch any mineral softer than itself, but can be scrathed by any mineral that is harder]]> 2017-10-23 14:33:03 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/199597485 Minerals from solutions pferrari1 https://padlet.com/marias8/5mfa1jj5cy56/wish/199598358 Sometimes the elements and compounds that from minerals can be dissolved in water o from solutions. 
A SOLUTION is a mixture in which one substance is dissolved in another

In a compound, 2 or more elements are combined so that the elements no longer have distinct properties. marias8 https://padlet.com/marias8/5mfa1jj5cy56/wish/199598557 2017-10-23 14:35:08 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/199598557 Cleavege and Fracture jalvarez17 https://padlet.com/marias8/5mfa1jj5cy56/wish/199600407 A mineral that splits easily along flat surfaces has the property called cleavage. The way atoms are arranged in micaallows to slit easily in one.  Fracture describes how a mineral looks whn it breaks apart in an irregular way.]]> 2017-10-23 14:38:15 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/199600407 Minerals from Magma and Lava pferrari1 https://padlet.com/marias8/5mfa1jj5cy56/wish/199601493 many minerals form from magma and lava. 

MInerals from as hot magma cools inside a crust , or as lava hardness on the surface. When these liquids cool to a solid state, they form crystals.

Elements such as copper, silver, and gold are also minerals. Almost all pure, solid elements are metals. ]]> 2017-10-23 14:42:22 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/199602759 jbolanos3 https://padlet.com/marias8/5mfa1jj5cy56/wish/199603625 The streak of a mineral is the color of its powder. However, the streak color and the mineral color are often different.]]> 2017-10-23 14:43:59 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/199603625 Where mineral Resources Are Found pferrari1 https://padlet.com/marias8/5mfa1jj5cy56/wish/199603921 Less common minerals are not found evenly throughout the crust. Instead, several processes can concentrate these minerals, o bring them together, in deposits. An ore is a deposit of valuable minerals contained in rocks. 
These ores are mined and the iron or lead is separated from the rock  ]]> 2017-10-23 14:44:32 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/199603921 jbolanos3 https://padlet.com/marias8/5mfa1jj5cy56/wish/199604584 Luster is the term used to describe how light is reflected from a mineral's surface.]]> 2017-10-23 14:45:48 UTC https://padlet.com/marias8/5mfa1jj5cy56/wish/199604584 Special Properties jalvarez17 https://padlet.com/marias8/5mfa1jj5cy56/wish/199605790 Some minerals can be indentified by special physical properties.

Recal that density is the mass in a given space, or mass per unit volume.

Then they plac the mineral in water to determine how much water the sample displaces. The volume of the displaced water equals the volume of the sample.
