Mohs Hardness Scale
The ________ indicates how prone a mineral or rock is to scratching.
Rocks
________ can be classified into 3 different groups based on how they are formed.
Colour
What ray of light shines onto the substance?
Colour
What ray of light shines onto the substance
Weight
How heavy is the object
Transparency
Is the object see through
Density
How compact are the substances particles
Hardness
Can this object get scratched or cut through by another object
Lustre
What type of shine is on the mineral
Streak
When scratched an object, wat colour powder does the mineral leave off
Granite
Granite is an intrusive igneous rock which is well known because of its salt and pepper colour
Diorite
Diorite is a form of granite and looks very similar to it
Pumice
Pumice is an extrusive igneous rock that is most known for its porous texture
Basalt
Basalt is an extensive igneous rock with a curved and glassy texture
Sandstone
Sandstone is a clastic sedimentary rock formed by compressed sand particles
Conglomerate
Conglomerate is a clastic sedimentary rock which is formed by small pieces of gravel stuck together with red mud
Shale
Shale is a clastic sedimentary rock which is formed by compressed silt or mud
Rock Salt
Rock salt is a chemical sedimentary rock where it is formed by sediments that are discovered after water evaporates
Chert
Chert is a chemical sedimentary rock comprised mainly of quartz
Dolomite
Dolomite is a chemical sedimentary rock comprised of calcite
Coal
Coal is an example of organic sedimentary rock and is mostly comprised of dead plant material compressed over the years
Coquina
Coquina is an organic sedimentary rock comprised of the shells of dead molluscs or clams
Chalk
Chalk is a variety of limestone which is known for its fine texture
Gneiss
Gneiss is a foliated rock where schist and other igneous rocks are put through intense heat and pressure
Slate
Slate is a fine grained and foliated rock, which is created under the alteration of shale or mudstone
Schist
Schist is a foliated metamorphic rock
Marble
Marble is a hard smooth rock made by limestone or chalk through strong heat and low pressure
Quartzite
Quartzite is created through high heat and pressure on quartz rich sandstone, which effectively fuses them together
Hornfels
Hornfels is a non foliated metamorphic rock which is usually quite dark in colour
