The rock cycle

mrs hacker's 7th grade science

QuestionAnswer
What is a naturally occuring solid mixture of one or more minerals or organic matter rock
the series of processes in which rocks forms, changes from one type to another, is destroyed, and forms again by geological processes the rock cycle
the process by which wind,water, ice, or gravity transports soil aND settlement from one location to another erosion
the chemical makeup of a rock; decribes either the minerals or other minerals in the rock composition
the quality of a rock that is based on the sizes, shapes, and positions of the rock's grains texture
when pieces of the Earth's crust collide together regional metamorphism
a change in the shape of the rock caused by a force placed on it deformation
rock that's grains are arranged in planes or bands foliated metamorphic rock
Name the 3 types of sedimentary rock clastic, chemical, organic sed. rock
a sedimentary rock consisting of usually quartz sand united by some cement sandstone
formed from remains of sea animals that have cemented together fossiliferous limestone
formed when fragments called clasts are cemented together clastic sedimentary
forms when a mineral crystallizes out of solution chemical sedimentary
example of chemical sed. rock sea water
name the formation of magma rock is heated, when pressure is released, and when rock changes composition
2 elements from mafic rock origin magnesium and iron
common structure found in metamorphic rock foliated
formed when plant material is buried beneath years of sediment coal
reveal the direction the wind and sand on sand dunes ripple marks
forms from the remains of of plants and animals that were once living organic sed. rock
when rock is heated by nearby magma contact metamorphism
minerals that form only in metamorphic rock at certain temperatures and pressures index minerals
forms from the remains of of plants and animals that were once living organic sed. rock
these rocks don't have alignment of the mineral grains nonfoliated metamorphic rock
made of fine silicate crystals and is used widely in industry benotite
rock that forms above or on the surface extrusive igneous rock
the arrangement of sedimentary rock into layers stratification
large irregular shapped intrusive bodies plutons
the largest formations of igneous rock batholiths
rock that forms below the earth's surface intrusive igneous rock
these rocks don't have alignment of the mineral grains nonfoliated metamorphic rock
formed in sheets across other already formed rock dikes
sheetlike but are other oriented parralel to previous formed areas sills
long cracks in the Eath's surface through which lava can flow fissures
smaller formations of igneous rock stocks
if a large amount of lava flows out of fissures and forms a new plain lava plateau
less dense than colored rocks felsic rock
dark colored rocks mafic rocks
a dramatice rise in this can cause a rock to melt temperature
when this is released around rocks that are hot , the minerals can then melt, forming magma pressure
the process by which rock within the Earth moves to the Earth's surface uplift
breaks down rocks into fragments weathering
layers of rock strata
What determines a rock's composition? the minerals that the rock contains
If igneous rock is fine grained, what can we tell about where it was formed? It was formed at the Earth's surface
Salt is formed when halite in shallow bodies of water___________ from solution. recrystallize
What are the two types of metamorphic rock foliated and nonfoliated
What must happen to sediments for sedimentary rock to be formed? compaction and cementation
What type of metamorphism occers because of intense pressure? regional metamorphism
the four processes that change rock inside the earth compaction and cementation, metamorphism, melting, cooling
