Composition of Igneous Rocks
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
What are sediments?
peices of soild material that have been deposited on Earth's surface by wind, water, ice, gravity, or chemical precipitation
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
What is lithification apart of?
burial
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
What is the bedding that is formed as inclined layers of sediment move forward across a horizontal surface?
cross-bedding
300
What are the three most common evaporite minerals and there chemical composition?
Calcite (CaCO3), Halite (NaCl), and Gypsum (CaCO4)
300
What is the process of a mineral change without the mineral melting?
fractional crystallization
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
What is the best known feature of sedimentary rocks?
fossils
400
What are examples of nplaces to find Medium-Grained Clastics?
Streams, river channels, beaches and deserts
400
What is the affect on hydrothermal fluids invading the surrounding rocks?
it changes their mineralogy, textures, and chemistry
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
What are the four main agents of erosion?
wind, moving water, gravity, and glaciers
500
What are the three rock types?
Clastic, Chemical, and Organic
500
What is the process of the rock cycle?
it starts with weathering and erosion, that makes sediment, which turns into sedimentary rocks, and over time becomes metamorphic rocks, then it produces magma, thast turns into igneous rocks, and then it starts all over
