The name for magma that forces its way into surrounding rock layers.
What is intrusion?
The way a mineral reflects light
What is luster?
Rocks that are light in color are called this.
What is felsic?
The hardness of a copper penny.
What is 3.5?
Some minerals like fluorite and calcite can glow in the dark when you shine this invisible light on them.
What is ultraviolet (UV) light?
The two primary ways minerals form from liquids are cooling (in magma or lava) and this process (in a solution).
What is evaporation?
Quartz and Halite have different crystal shapes due to this.
What is the internal arrangement of atoms?
The four main groups of igneous rocks.
What are Ultramafic, Mafic, Intermediate, and Felsic?
This process occurs directly after sediments are sorted.
What is deposition?
The official NYS gemstone
What is Garnet?
Heat and pressure form this SPECIFIC type of rock with bands of minerals that look like stripes.
What is Gneiss?
Which two minerals are softer than a human fingernail?
What are graphite and halite?
This mineral would be the third to melt when heated.
What is Potassium Feldspar?
With heat and pressure, metasandstone turns into this rock.
What is quartzite?
This liquid chemical compound fails to be a true mineral because it is naturally a liquid at room temperature instead of a solid.
What is water?
This fine-grained, dark volcanic rock makes up most of the oceanic crust and is the extrusive equivalent of gabbro.
What is basalt?
The most common mineral in beach sand.
What is quartz?
Basalt contains this type of plagioclase feldspar.
What is calcium-rich?
This grain size found in sedimentary rocks is the largest.
What are cobbles?
The name of the only rock that can float
What is Pumice?
As water or wind carries sediment farther from its source rock, a drop in this measure of speed and direction causes the grains to become sorted.
What is velocity?
Quartz, Amphibole, Pyroxene, and Galena are placed together in a closed, dry container and shaken vigorously for 10 minutes. This mineral sample would experience the most abrasion.
What is galena?
As you move from the top of the Bowen's Rxn Series Chart, these two things increase and these two things decrease.
Increase: Stability and Silica
Decrease: Pressure and Temperature
As coal is forming from plants it is first called this.
What is peat?
