Hard Rock
The process where rock is made, changes from one form to another, is destroyed and reforms by geological processes.
What is the rock cycle?
Rock that forms when magma cools and solidifies.
What is igneous rock?
Loose pieces of rock, minerals and organic materials.
What are sediments?
Rocks that change from one type to another without completely melting.
What are metamorphic rocks?
Large (more than 100 km2) intrusive formations exposed on Earth's surface.
What are batholiths?
Determines the chemical stability of minerals in a rock.
What is the strength of chemical bonds?
The process where minerals melt at different temperatures.
What is partial melting?
Process where minerals fill spaces between sediments and hold them together (like glue).
What is cementation?
Changes in texture, structure or chemical composition due to touching magma directly.
What is contact metamorphism?
Intrusive rock formation made when magma cuts across rock layers.
What is a dike?
The simple pattern that shows the order minerals crystallize from magma.
What is Bowen's reaction series?
When crystals form and different minerals are removed from cooling magma.
Sedimentary rock made from the remains of plants or animals such as coal and limestone?
What is organic sedimentary rock?
Then there are planes or bands of mineral grains arranged in metamorphic rocks
What is foliation?
Extrusive rock formation that is a vent by which magma, gases or ash is expelled.
What is a volcano?
The process of chemical and mechanical breakdown of rocks.
What is weathering?
What is felsic rock?
The layering of sedimentary rock.
What is stratification?
Changes in texture, structure or chemical composition due to being in the area of magma or tectonic activity.
What is regional metamorphism?
Sedimentary rock feature where largest sediments are on the bottom layer; with each layer above being smaller.
What is graded bedding?
The three factors that determine if a rock melts.
What are temperature, pressure and the presence of fluids?
Rock formed from cooling and solidification of lava at Earth's surface.
What is extrusive igneous rock?
The order sedimentary rock is classified by sediment size: (from largest to smallest)
What is conglomerate, breccia, sandstone, and shale.
The three factors that may cause metamorphism.
What are heat, pressure and hot fluids.
What are concretions?
