The Rock Cycle
a sequence of events involving the formation, alteration, destruction, and reformation of rocks
weathering
the destructive process by which rocks are changed on exposure at or near the earth?s surface, with little or no transport of loosened or altered material
erosion
the wearing away of soil and rock by the action of streams, glaciers, waves, wind, underground water, and gravity
transportation
the movement of sediment by natural agents either as solid particles or in solution, from one place to another on the earth?s surface
deposition
the laying-down of rock-forming material by any natural agent
SEDIMENT
solid, fragmented material transported and deposited that forms in layers of loose unconsolidated material
lithification
the conversion of newly deposited sediment into a solid rock
SEDIMENTARY ROCK
a layered rock resulting from consolidation of sediment
metamorphism
the mineralogical, chemical, and structural adjustment of solid rock to physical and chemical conditions different from where the rock was formed
METAMORPHIC ROCK
any rock derived from pre-existing rocks (by metamorphism)
MAGMA : naturally occurring molten rock material generated within the earth
eruption through the surface of earth OR move through earth
melting
the process of turning a solid rock into a liquid
MAGMA
naturally occurring molten rock material generated within the earth
intrusion
the process of emplacement of magma in pre-existing rock below the earth?s surface
INTRUSIVE IGNEOUS ROCK
rock formed by cooling and solidification of magma below the earth?s surface
extrusion
the emission of magma onto the earth?s surface (where it changes name to become LAVA)
EXTRUSIVE IGNEOUS ROCK
rock formed by cooling and solidification of lava above the earth?s surface
exhumation
the process of exposing previously buried rock at the earth?s surface by removal (erosion) of the overlying material
elementary particles
the most basic indivisible components of all the matter in the universe ? as of today; smallest known particles and all things larger are made of multiple particles; ex.
protons/neutrons/electrons (subatomic particles)
basic components of atoms and the basis upon which most chemistry and biochemistry research is derived; ex.
atoms (elements)
the smallest unit of matter that can take part in a chemical reaction and which cannot be broken down chemically into anything simpler; ex
Rocks
minerals are the building blocks of rocks and rock are what makes the world work
atoms (elements) : the smallest unit of matter that can take part in a chemical reaction and which cannot be broken down chemically into anything simpler; ex. oxygen, carbon; classified in 3 categories
- metals
- nonmetals
- metalloids
- hydrogen and helium were the only elements formed in The Big Bang
- elements up to Iron [atomic number 26 (carbon, oxygen, etc.)] were/are formed during nuclear fusion in stars
- only atoms as large as Iron can be made with stars; anything larger (copper, zinc, etc.) is only produced during supernovae
- the most abundant element in the crust is oxygen; second is silica
minerals
form as a result of geologic process which cause specific elements to combine; ex.
minerals : form as a result of geologic process which cause specific elements to combine; ex. quartz, mica, calcite; there are 5 defining characteristics of minerals
- naturally occurring
- homogenous
- solid
- definite chemical composition
- characteristic crystal structure
