my vocab over chapter 4

A naturally occuring solid mixture of 1 or more minerals & organic matter is? ROCK
The continual processes in whick new rock forms old rock material is called? ROCK CYLCE
The process by which wind, water, ice, or gravity transport soil & sediment from one location to another is called? EROSION
A process in which material is laid down is called? DEPOSITION
A chemical makeup of a rock; describes either the materials or other materials in a rock is called? COMPOSITION
The quality of a rock that is based in the sizes, shapes, & positions of the rocks grains is called? TEXTURE
A movement within the earth causes rocks inside the earth to be moved to the earths surface? UPLIFT
What rock formed from the cooling & solification of magma beneath the earth's surface? INTRUSIVE INGNEOUS ROCK
What kind of rock forms as a result of volcanic activity at or near the earth's surface? EXTURSIVE IGNEOUS ROCK
What are the layers of rock called? STRATA
The process in which sedimentary rocks are arranged in layers is? STRATAIFICATION
The texture of metamorphic rock in which the mineral grains are arranged in planes or bands is? FOLIATED
A texture of metamorphic rock in which the mineral grains are NOT arranged in planes or bands is? NONFOLIATED
the continual process by which new rock forms from old rock material ROCK CYCLE
the four processes that SHAPED earth's surface 1. weathering 2. erosion 3. deposition 4. uplift
breaks down rock into framents weathering
removes sediment from its source erosion
as a sediment drops & comes to rest, sedimentary rock is formed deposition
the process by which rock within the earth moves to the earth's surface uplift
occurs when the temperature & pressure are high enough change sedimentary rock into metamorphic rock. Metamorphic rock formation
occurs when the rock gets hot enough to melt. Once it melts it forms magma, when it cools, it forms igneous rock igneous rock formation
the four processes that changed INSIDE the earth 1. compaction & cementation 2. metamorphism 3. melting 4. cooling
the minerals that a rock contains composition
describes the size, shape, and position of a rocks grains. also gives clues on how a rock was formed texture
texture determines how fast OR slow magma cools. If magma cools quickly the rock is fine grained. If it cools slowly the rock is medium to course grained Igneous Rock
*when rock is heated *when pressure is released *when rock changes composition are 3 ways magma can form
*light colored *less dense than dark colored rocks *Aluminum (AL) Potassium (K) Sodium (NA) Silicon (SI) Felsic Rocks
*dark colored rocks *rich in calcium (CA) Iron (FE) and Magnesium (MG)and is POOR in Silicon (SI) Mafic Rock
rock that forms BELOW earth's surface Intrusive Igneous Rock
Rock that forms ABOVE the earth's surface Extrusive Igneous Rock
*plutons, *batholiths, *Stocks, *dikes, * sills are types of intrusive igneous rock
rock that is formed when clasts are cemented together CLASTIC SEDIMENTARY ROCK
a rock that forms when a mineral crystallizes out of solution EX: sea water --> rock CHEMICAL SEDIMENTARY ROCK
a rock that forms from the remains of plants and animals that were once living ORGANIC SEDIMENTARY ROCK
formed from the remains of sea animals that have cemented together Fossiliferous Limestone
a type of organic sedimentary rock coal
the direction of wind and sand on sand dunes is called? Ripple MArks and Mudcracks
a form of clay, which is a sedimentary rock Benodite
means (changed) Meta:
means (shape) Morphos
means (gneiss) Shale
rocks in which structure, texture, or comopistion has changed MEtamorphic Rock
this is when rock is headed by nearby magma. Contact Metamorphism
*intense pressure when peices of earths crust collide Regional Metamorphism
forms only in metamorphic rock at certian temperature and pressure Index Minerals
these are usually formed minerals that are flat Foliated Metamorphic Rock
contact metamorphism involves a VERY high temperature Nonfoliated Metamorphic Rock
a change in shape of a rock caused by a force places on it. Deformation
the arrangement of sedimentary rock inot layers Stratification
minerals that form only in metamorphic rock at certian temperatures and pressure Index Minerals
These are usually formed from minerals that are flat FOLIATED Metamorphic Rock
contact metamorphism involves a very high temperature that results in nonfoliated metamorphic rock formaion Nonfoliated metamorphic Rock
a change in shape of a rock caused by a forcce on it Deformation
