100
In this process _______ is crystallized beneath the surface to form igneous rocks.
What is magma?
100
This texture is affected by slow cooling creating large crystals.
What is Course-Grained texture.
100
Pieces of solid material that have been deposited on Earth's surface by wind, water, ice, gravity or chemical precipitation.
What are sediments?
100
What is a clastic sedimentary rock?
a rock that is formed from the abundant depositis od loose sediments found on Earth's surface
100
What is granitic composition?
Igneous rocks made up of mostly the light colored silicates quartz and feldspar?
200
The types of igneous rocks below and on the earth's surface.
What are extrusive and intrusive?
200
This texture is affected by rapid cooling of magma or lava.
What is Fine-Grained texture?
200
The five steps in the formation of sedimentary rocks.
What are weathering, erosion, deposition, compaction and cementation?
200
What are the three types of clastic sedimentary rocks?
Coarse-Grained Clastics, Medium-Grained Clastics, and Fine-Grainned Clastics
200
What is basaltic composition?
Rocks that contain dark silicate minerals and plagioclase feldspar.
300
Type of igneous rock that forms when lava hardens on the earth's surface.
What is extrusive igneous rock?
300
The textures of rocks are greatly affected by this.
What is rate of cooling?
300
The part of the process that involves glueing dissolved minerals into tiny spaces among sediments.
What is cementation?
300
What are the three most common evaporite minerals and there chemical composition?
Calcite (CaCO3), Halite (NaCl), and Gypsum (CaCO4)
300
Rocks with composition between granitic and basaltic with 25 percent dark silicate minerals.
What is andesitic?
400
Rocks that are formed when magma hardens beneath the earth's surface
What are intrusive igneous rocks?
400
the rocks texture made by large well-formed crystals called phenocrysts and surrounded by smaller grained crystals.
What is porphyritic texture?
400
The squeezing or pressing together of sedimentary rocks.
What is compaction?
400
What are examples of nplaces to find Medium-Grained Clastics?
Streams, river channels, beaches and deserts
400
Rhyolite is an extrusive rock that has a _________ composition.
What is granitic?
500
The two characteristics used to classify igneous rocks.
What are texture and composition?
500
This texture results when there is not enough time for ions in lava to arrange themselves.
What is glassy texture?
500
Removal of rocks by water, wind, gravity or ice.
What is erosion?
500
What are the three rock types?
Clastic, Chemical, and Organic
