Question | Answer |
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 |
