Rock
A solid aggregate of minerals or mineraloids.
Mineral
Naturally occurring inorganic substance with a definite composition.
Rock Cycle
Continuous process of rock formation and transformation.
Igneous Rock
Formed from cooled and solidified magma or lava.
Sedimentary Rock
Formed from sediment compaction and cementation.
Metamorphic Rock
Formed from existing rocks under heat and pressure.
Magma
Molten rock beneath the Earth's surface.
Lava
Magma that reaches the Earth's surface.
Extrusive Rock
Igneous rock formed from lava on the surface.
Intrusive Rock
Igneous rock formed from magma below the surface.
Mafic Rock
Igneous rock rich in magnesium and iron.
Felsic Rock
Igneous rock rich in silica and aluminum.
Weathering
Process breaking down rocks into sediments.
Erosion
Movement of sediments by wind, water, or ice.
Deposition
Accumulation of sediments in new locations.
Compaction
Process of sediments being pressed together.
Cementation
Binding of sediments by minerals during lithification.
Clastic Rock
Sedimentary rock formed from fragments of other rocks.
Biogenic Rock
Sedimentary rock formed from biological activity.
Chemical Rock
Sedimentary rock formed from mineral precipitation.
Foliation
is the movement of minerals into layers
Dichotomous Key
Tool for identifying rocks based on characteristics.
Chemical weathering
a process that breaks down rocks and minerals through chemical reactions with water, air, or other substance
biogenic
processes related to living organisms that contribute to the formation of rocks and minerals.
clastic
relating to sediments or rocks composed of fragments of pre-existing rocks or minerals.
chemical
related to substances and their interactions, often involving reactions that alter mineral composition.
biological weathering
the process by which living organisms contribute to the breakdown of rocks and minerals, often through physical or chemical means.
deposition
the geological process in which sediments, soil, and rocks are added to a landform or land mass, often occurring through water, wind, or ice.
physical weathering
the process of breaking down rocks and minerals through physical forces without altering their chemical composition, often caused by temperature changes, freeze-thaw cycles, or abrasion.
the process of a sedimentary rock
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock
Foliation
process when minerals under pressure become squashed flat and rocks develop layers or bands (wavy)
regional metamorphism
Is when the rock is altered by both heat and pressure
Contact metamorphism
When it is mostly altered by heat it occurs over small areas of hot magma
Dynamic metamorphic
when the rock is altered by mostly pressure it occurs in a small area where the crustal rocks are scraping
crystal structure
he particular repeating arrangement of atoms (molecules or ions
granite
Granite is a light-colored plutonic rock found throughout the continental crust, most commonly in mountainous areas big crystals
basalt
Basalt is a dark-colored, volcanic rock that's made of fine-grained crystals no crystals
magma
hot fluid or semi-fluid material below the earth crust
