Minerals
True/False: A mineral must be a solid.
True!
This process breaks down rock due to storms, rain, freezing, and wind.
What is weathering?
This is how igneous rocks are formed.
What is the cooling of magma or lava?
This is how metamorphic rocks are formed.
What is heat and pressure?
How many rock types make up the rock cycle?
3!
These are the type of minerals that make up rocks.
What are rock-forming minerals?
Sedimentary rocks are made up of these things:
Particles of rock, remains of plants and animals
What is magma?
This is the process by which metamorphic rock turns into igneous rock.
What is melting (and/or cooling)?
True or false: there is just one path that a rock can take through the rock cycle.
False! There are MANY paths a rock can take through the rock cycle.
Minerals form from this type of process, which means it forms from nonliving things.
What are inorganic processes?
This process packs particles together.
What is compaction (or cementation)?
This type of igneous rock is formed when lava cools above the Earth's surface.
What is extrusive rock?
Rocks need _____ & ________ to change into metamorphic rocks.
What is heat and pressure?
Earth's crust is made up of enormous _______, or slabs of rock, that float and move over the mantle. When they move, they cause earthquakes, tsunamis, and volcanoes.
What are tectonic plates?
What is crystal structure?
During this process, wind and water move and blow particles of broken-up sediment away and apart from the rock formation.
What is erosion?
This type of igneous rock is formed when magma cools beneath the Earth's surface.
What is intrusive rock?
Rocks with stripes have different materials that are tightly packed together. We call these rocks...
Banded (or foliated)
When magma cools, what type of rock does it become?
Igneous rock
This is the type of composition a mineral must have.
What is a definite chemical composition?
This type of sedimentary rock is made up of different pieces of rock compressed together.
What is clastic rock?
This type of igneous rock is shiny and black, and has historically been used to make tools and weapons because of its sharp edges.
What is obsidian?
This type of metamorphic rock is used for to build buildings, or statues such as David by Michaelangelo.
What is marble?
When sedimentary rock is exposed to heat and pressure, what type of rock does it become?
Metamorphic rock
