A natural, solid mixture of minerals or particles is called this.
Rock
Igneous rock that formed from magma and cooled very slowly UNDERNEATH the earth's surface is called this.
Intrusive Igneous Rocks
These small pieces or particles make up the sedimentary rock. They can be other rocks or plant and animal organisms.
Sediments
Metamorphic rocks are created by these two primary forces.
Extreme Pressure and Temperature
Geologists classify rocks into these 3 major groups.
Igneous, Sedimentary, and Metamorphic Rocks
The type of rock that forms from magma or lava cooling is termed this.
Igneous Rock
This type of rock is formed from lava ON the earth's surface.
Extrusive Igneous Rocks
The process that squeezes out fluids and decreases the space between the grains in a sediment deposit is called this.
Compaction
These types of rocks can become metamorphic rocks.
Igneous, Sedimentary, and other Metamorphic Rocks
A rock transforms into sediment through these two processes.
Weathering and Erosion
The fragments that make up a rock and its texture are called this.
Grains
This intrusive igneous rock has larger crystals and is what Stone Mountain is primarily composed of.
Granite
The crystallization of minerals from water into the spaces between sediment grains that makes sedimentary rocks stick together is called this.
Cementation
This occurs when magma comes in contact with existing rock and its thermal energy and gases interact with the surrounding rock to make new metamorphic rock.
Contact Metamorphism
Prior to becoming igneous rock, this process must occur to any rock.
Melting
The grain size and the way grains fit together in a rock are called this.
Texture
This type of extrusive igneous rock is black with a glassy texture.
Obsidian
A broken piece or fragment of rock that comprises a sedimentary rock is called this.
Clast
A rock that contains parallel layers of flat and elongated minerals is termed this.
Foliated Metamorphic Rock
The tectonic process that forces rocks onto the earth's surface is called this.
Uplift
The series of processes that change one type of rock into another type of rock is called this.
Rock Cycle
This igneous rock is very light and can float in water. It also has holes due to the release of gases and is used as an abrasive.
Pumice
This type of sedimentary rock is made up of broken pieces of rock and minerals.
Clastic Sedimentary Rock
The formation of metamorphic rock bodies that are hundreds of square kilometers in size often occurs when rocks undergo pressure at fault lines is called this.
Regional Metamorphism
The cause of chemical weathering which combines the element oxygen with other elements or molecules is called this.
Oxidation
