Igneous Rocks
This can cool and harden and form igneous rock.
What is magma or lava?
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
What are sediments?
What are the two types of mining
Surface/Subsurface
Name the three types of rock groups.
What is Sedimentary, Igneous and Metamorphic?
The process of rocks changing from one kind of rock to another kind of rock over long periods of time.
What is the rock cycle?
This kind of igneous rock is formed when magma cools beneath the Earth's surface.
What is Intrusive igneous rock?
These are two ways that sediments are formed.
What is weathering and erosion?
Which form of mining has a greater impact on the environment?
Surface mining
A fossil is ___________.
What is the impression of an organism on a rock?
Name two ways people use rocks.
What is buildings, walls, roads, jewelry, decoration, countertops?
This type of igneous rock forms when lava cools on the Earth's surface.
What is Extrusive igneous rock?
These 2 things cause metamorphic rocks to form.
What are heat and pressure?
What is the process of searching for minerals called?
What is prospecting?
A naturally occurring, inorganic solid, that has a definite chemical composition and crystal structure.
What is a mineral?
What happens if an igneous rock weathers? What rock does it turn into?
What is sedimentary rock?
This type of igneous rock is black with a glassy texture. We looked at it in class.
What is obsidian?
For an Igneous rock to become a sedimentary rock, what needs to happen?

Costs/Geology/Climate/Accessibility/EIA/Supply and Demand
Are made of minerals (sometimes fragments of other rocks) and in some cases, they also contain organic material
What is a rock?
The hardest mineral.
What is a diamond?
This determines the size of crystals that form in igneous rocks.
What is the cooling rate of the magma or lava?
The type of sedimentary rock that can contain fossils.
What is organic sedimentary?
Searching for minerals: Samples are sent to a laboratory for ___________ analysis
What is geochemical?
This is a process in which pollutants from waste are removed via living organisms. They break it down and process them into less harmful substances
What is bioremediation?
Explain the difference between bioaccumulation and biomagnification.
The process by which a chemical substance builds up inside a living organism over time because the organism absorbs it faster than it can break down or excrete.
The process by which the concentration of a substance (like toxins) increase as it moves up the food chain.
