Rocks
Rock that forms from the cooling of magma below the surface or lava at the surface is called
Igneous
Metamorphic rocks form under these two conditions.
What are heat and pressure?
When mineral grains in a metamorphic rock line up in bands or layers, the rock is called this.
What is foliated?
This is the measure of how easily a mineral can be scratched.
What is hardness?
This process turns rocks into smaller sediments.
What are weathering and erosion?
Igneous rocks with large crystals cooled (slowly/quickly)?
What is slowly?
Rocks formed from cooling magma below Earth’s surface are called this.
What are intrusive igneous rocks?
Rocks formed from lava cooling quickly on Earth’s surface are called this.
What are extrusive igneous rocks?
A mineral that breaks along smooth, flat surfaces shows this property.
What is cleavage?
When sediments are pressed and glued together, they form this type of rock.
What are sedimentary rocks?
Rocks that form when minerals dissolved in water crystallize are called this.
What are chemical sedimentary rocks?
What rock forms from a layering of weathered sediments?
What is sedimentary rocks?
Although brick, steel, and glass all come from substances found in Earth’s crust, they are NOT classified as minerals because
What is not naturally occurring?
The color of a mineral’s powder when rubbed on a plate is called this.
What is streak?
When any rock melts and cools, it turns into this type of rock.
What are igneous rocks?
All rocks can eventually melt into this molten material.
What is magma?
Igneous rocks with small crystals cooled this way.
What is quickly?
If a mineral can scratch calcite (3) but not quartz (7), its hardness is most likely around this number.
What is 4–6?
The way a mineral reflects light (shiny, glassy, dull) is called this.
What is luster?
When any rock is buried and exposed to extreme heat and pressure, it becomes this type of rock.
What are metamorphic rocks?
Sedimentary rock turning into metamorphic rock requires this.
What are heat and pressure?
Gneiss has this banded texture.
What is foliated?
Chalk is made from the tiny shells of ocean organisms. It is an example of what type of rock?
What is sedimentary rock?
The repeating pattern of atoms that makes up a mineral forms this solid structure.
What is a crystal?
The cycle that describes how rocks change from one type to another is called this.
What is the rock cycle?
