Minerals
This category include Vitreous, Earthy, and Pearly.
What is luster.
What determines the size of the grains in an igneous rock?
What is how it cools.
Small pieces of rock that are broken off of larger rock beds.
What are sediments.
The term we use to describe a metamorphic rock that displays clear layers caused by the parallel alignment of mineral crystals.
What is foliated.
When heat and pressure are applied to a rock.
What is a change of the original rock to a metamorphic rock.
The scale used to test a mineral's hardness.
What is Moh's hardness scale.
Igneous rocks that cool or crystallize on the surface of the earth.
What are extrusive igneous rocks.
Forces such as water and wind that produce rock and mineral fragments.
What is weathering.
The recrystallization of existing rock under high temperature and pressure creates this type of rock
What is metamorphic
The process by which rocks are broken down into sediments, by agents such as water and wind.
What is erosion.
A naturally occurring, solid, inorganic compound or element.
What is a mineral.
The term used for igneous rocks that are dark colored, have low silica content, and contain mostly plagioclase and pyroxene.
What are basaltic or mafic igneous rocks.
The three classifications of sedimentary rocks.
What is clastic, chemical, and biochemical.
Metamorphic rocks are classified by?
What are foliated and nonfoliated.
True or False. In the rock cycle, we can go from magma to sediments.
What is False
The term refers to the regular, geometric shapes that occur in many minerals.
What are crystals.
The term used for igneous rocks with well-formed crystals surrounded by finer-grained crystals.
What is Porphyritic.
The type of bedding results in a sedimentary rock with grains sorted by size, largest on the bottom, finest on the top
What is graded.
When molten rock (lava or magma) comes into contact with solid rock and the high temperature causes the rock to undergo a metamorphic change.
What is contact metamorphism.
True or False. Igneous rock can become a metamorphic rock without ever breaking down into sediment.
What is True.
The combination of the elements, silicon and oxygen, form this mineral group.
What are silicates.
Pumice is an example of this igneous rock texture.
What is vesicular.
Occurs when sediment gets deposited as the energy of the transporting agent, especially water, decreases.
What is deposition.
When temperature and pressure affect a large area of Earth's crust.
What is regional metamorphism.
True or False. A rock can go straight from metamorphic to igneous.
What is False.
