Rocks
The 3 main types of rocks.
What is igneous, sedimentary, and metamorphic rock?
What is a diamond?
Molten material that forms deep beneath Earth's surface.
What is magma?
The average movement of the lithosphere plates.
What is 5cm per year?
Three main sciences involved in Earth Science.
What is geology, meterology, and astronomy?
This type of rock forms as a result of heat and pressure.
What is metamorphic rock?
Name one of the characteristics that a material must have to be considered a mineral.
What is formed by natural geologic processes, solid, crystalline structure, a chemical compound made of two/more elements(most), most are inorganic crystalline solids found in nature?
The particles produced in volcanic eruptions.
What is pyroclastic materials?
What is a convergent boundary?
Main two materials that made up the cloud our solar system evolved from.
What is helium and hydrogen?
Sedimentary rocks with ripple marks suggest that the rocks formed here.
What is along a beach or stream bed?
This measures the hardness of a mineral.
What is Mohs scale?
This type of volcano is fairly symmetrical and has both layers of lava and pyroclastic deposits.
What is a composite cone volcano?
The theory of plate tectonics helps explain this.
What is how earthquakes and volcanic eruptions occur.
The asthenosphere and lithosphere are part of this sphere.
What is the geosphere?
Lava that cools so quickly that ions do not have time to arrange themselves into crystals will form igneous rocks with this texture. fine-grained, coarse-grained, or glassy texture.
What is glassy texture?
Name one of the ways that minerals can form.
What is crystallization from magma, precipitation, pressure & temperature, and hydrothermal solutions?
Name a factor that determines how violently or quietly a volcano erupts.
What is magma's composition, temperature, and concentration of dissolved gases?
What is an oceanic plate that is pushed down into the mantle? (One plate is pushed down under the other)
A Mercator project map shows tis accurately.
What is directions?
Consider coal, andesite, rhyolite, and granite. Name the example of an extrusive igneous rock.
What is rhyolite?
What is fizz?
Lava plateaus form this way.
What is fluid basaltic lava flows out of fissures?
This results when divergence occurs within the oceanic lithosphere. a rift valley, a volcano chain, a mountain ranage, or seafloor spreading
What is seafloor spreading?
On a topographic map, contour lines that form a circle.
What is a hill?
