The color of a mineral's powder when rubbed against a porcelain plate.
What is streak?
The process where water, wind, and ice break down rocks into smaller pieces.
What is weathering?
This metamorphic texture is characterized by a "banded" or "layered" look.
What is foliation?
Resources like solar and wind that can be replaced in a short period of time.
What are renewable resources?
This term refers to any useful mineral or rock that can be mined for a profit.
What is an ore?
Of the three main types of fossil fuels, this one is considered the 'cleanest' burning because it releases the fewest emissions, yet it is often the most difficult to transport without pipelines.
What is Natural Gas?
This scale is used to rank a mineral's resistance to being scratched, from 1 to 10.
What is the Mohs Hardness Scale?
This type of igneous rock forms on the Earth's surface and usually has very small or no visible crystals.
What is extrusive rock?
These are the three main types of sedimentary rocks: Clastic, Chemical, and this type made from once-living things.
What is organic?
This solid fossil fuel formed from the remains of ancient swamp plants.
What is coal?
This type of mining involves removing the "overburden" (top layer of soil and rock) to reach resources near the surface.
What is surface or strip mining?
This term describes a mineral that was never alive and did not come from a living thing.
What is inorganic
The two-part process of "lithification" that turns sediment into solid rock.
What are compaction and cementation?
This common sedimentary rock is made of shells and often fizzes when it touches acid.
What is limestone?
This type of energy is generated by using the heat from inside the Earth's crust.
What is geothermal energy?
This is the process of restoring land to its original state after mining operations have finished.
What is reclamation?
This mineral group is the most common in Earth's crust and is defined by the presence of Silicon and Oxygen.
What are Silicates?
DAILY DOUBLE
If an igneous rock is subducted deep into the Earth, it must first undergo this process before it can eventually become a new igneous rock.
What is melting
"Contact Metamorphism" happens when rock is "cooked" by this substance.
What is magma or lava?
This is the most abundant fossil fuel in the United States, often moved by trains.
What is coal?
To conserve non-renewable resources, we can use the "3 Rs": Reduce, Reuse, and this.
What is Recycle?
While color can be misleading, this property refers to the way a mineral surface reflects light, such as "pearly" or "vitreous."
What is luster?
To transform a sedimentary rock into a metamorphic rock, it must be subjected to these two forces without melting.
What are heat and pressure?
When the sedimentary rock Shale is metamorphosed, it usually turns into this "daughter" rock.

What is Slate?
Fossil fuels are essentially "stored" energy from this original source.
What is the Sun?
This environmental phenomenon occurs when sulfur-rich minerals in mining waste react with water and oxygen to create highly acidic runoff.
What is Acid Mine Drainage?
