Properties of Minerals #1
A solid inorganic material found in nature but not from living things such as plants and animals.
What is a mineral?
Metallic, Dull, Glassy, Pearly, or Earthy
What are the types of luster?
This forms when melted rock from inside Earth cools and hardens
What is igneous rock?
Sediment is known to have what in it
What is tiny pieces of rocks, shells, mineral grains, and other minerals?
A metamorphic rock is considered a "recycled" rock due to the process of
What is heat and pressure?
A solid material that has an orderly repeating pattern of atoms
What are crystals?
Scraping a mineral across an unglazed white tile to produce a color that is more accurate to identifying a mineral
What is streak?
Cracks within the Earth's crust
What is fissures?
Formed when sediment collects in layers to form a rock which takes thousands to millions of years
What is sedimentary rock?
Means "change of form"
What is metamorphic?
A mineral can come in many types of these which can fool many people when trying to identify them.
What is color?
To identify the firmness of a mineral you must use this based on their scratch
What is the Mohs scale?
When lava flow cools on Earth's surface or in water
What is extrusive igneous rock?
Formed when tiny mineral and rock grains are deposited in layers, pressed down, and cemented together
What is detrital sedimentary rock?
Due to the heat and pressure put onto this rock, there are visible layers of different colored minerals
What are foliated rocks?
Minerals break into smooth pieces with flat even surfaces that reflect light
What is cleavage?
How light reflects off of a minerals surface
What is luster?
Melted rock inside the Earth
What is magma?
For a chemical sedimentary rock to form, what needs to take place over and over time which leaves behind a layer of minerals
What is water that is rich in minerals (ocean water) evaporates?
With non-foliated rocks you cannot see the individual grains of minerals due to them have
What is a more even-color?
Minerals that break into uneven chunks with rough edges which do not have even patterns along the breaks
What is fracture?
This mineral is considered the hardness mineral on the scale
What is a diamond?
When a huge glob of magma cools below the surface of Earth is forced upward but never actually gets to the surface
What is intrusive igneous rock?
Form from the remains of dead creatures that pile up in layers, where the layers compass together to form rock over millions of years
What is organic sedimentary rock?
A great example of a non-foliated rock is
What is marble?
