Rocks
Metamorphic, sedimentary, and igneous
What are the three major rocks?
Is a solid material. a repeating arrangement of crystalline atoms. It is naturally occurring. Is not inorganic, and it has a specific chemical composition.
What is a mineral?
Pumice, obsidian, and basalt.
What are types of igneous rocks?
Conglomerate, breccia, sandstone, siltstone, and shale
What are types of sedimentary rocks?
Marble and quartzite
What are types of metamorphic rocks?
Crystallization, erosion and sedimentation, and metamorphism.
What are the processes of the rock cycle?
What is a minerals physical properties?
A type of rock formed from the cooling of magma or lava.
What is a Igneous rock?
This rock forms in horizontal layers with older years on the bottom.
What is a sedimentary rock?
Existing rocks that are changed by heat and pressure underground.
What is a metamorphic rock?
The most common type of rock on Earth's surface.
What is sedimentary rock?
What is the most common mineral on Earth?
This rock cools and solidifies below the surface. It forms plutons (called plutonic). And it contains large crystals because of a slow cooling rate. Ex. granite.
What is a Intrusive Igneous rock?
Sediments that form a rock through compaction or through cementation.
What is sedimentary rock formation?
Changing a rock without melting
What is metamorphism?
Made of a collection of mineral grains that are held together in a solid mass, naturally form, and are non-living Earth materials.
What are rocks?
Every day objects being scratched on rocks and minerals to test the hardness.
What is Moh's Hardness Scale?
This rock cools and solidifies at the surface. Is usually from a volcano so called volcanic rocks. Cools quickly causing small crystals to form. It may have holes from gas bubbles.
What is an Extrusive Igneous rock?
Sediments forming a sedimentary rock through lots of pressure and being squeezed together.
What is compaction?
A wide area of metamorphic rock caused by extreme pressure from overlying rock.
What is regional metamorphism?
Minerals contained inside a rock, the texture of the rock, some rocks are not made of minerals.
What is identifying a rock?
The four sided molecule that consists of four oxygen atoms and one silicon atom. This molecule is found in All silicate minerals.
What is the silica tetrahedra?
felsic - light color and low density
intermediate - middle color and density
mafic - dark color and high density
ultramafic - very dark and heavy.
What is Igneous rock classification?
Form in oceans and salt lakes.
What are biochemical sedimentary rocks?
A rock that came into contact with magma and extreme heat.
What is contact metamorphism?
