Rock Test

QuestionAnswer
ways magma is formed changes in composistion
what texture does igneous rock have when magma cools slowly coarse-grained
what texture does igneous rock have when magma cools slowly fine-grained
what kind of rock forms when magma intrudes other rock intrusive igneous rock
what kind of rock is formed when lava cools on the earths surface extrusive igneous rock
solid mixture of crystals or one or more minerals rock
process by which new rock forms from old rock rock cycle
prosses by which sediment is removed from its source erosion
prosses by which sediment is dropped and comes to rest deposition
the chemical make up of the rock composition
size shape and position of grains that make up a rock texture
which rock is not normally used as a constrution material halite
which prosses changes rock on earths surface erosion
when sedimentry rock is exposed to heat and pressure what does it change into metamorphic rock
what do scientists classify rocks by composition and texture
a naturaly occuring solid mixture rock
prosses by which new rock form form old rock rock cycle
what have rocks been used for in history buildings and tools
what affects rockin earth pressure
a rock on earths surface is affected by weathering and erosion
a rock under ground is affected by extrem heat and pressure
what mineral is formed when metamorphic rock melts magma
what rock is formed when igneous rock is subjected to weathering erosion compaction and cementation sedimentary rock
what new kind of rock is formed when sedimentary rockis subjected to heat and pressure metamorphic rock
magma in the earths crust that has risen to the surface and cools and solitifys igneous rock
rock that is forced downward and is exposed to heat and pressure metamorphic rock
rocks that are partially or completlly melted magma
igneous rock at the earths surface that is weathered and wears away sediment
sediment that washes down into rivers and oceans and is pressed and cemented together sedimentary rock
the process in which water wind ice and heat break down rock is called weathering
one reason that weathering is important is because it breaks rock down into fragments or ______ from which sedimentary rocks are made sediment
the process by which sediment is removed from its source is called erosion
during ______ sediment is deposited in bodies of water and other low lying areas depostion
sedimentary rock can be made when sediment is pressed and cemented together by ______ dissolved in water minerals
some ______ rock is made when sedimentis squeesed by the weight of the rock materials that lies above it sedimentary
movement within the earth that causes buried rock to be exposed at the earths surface is called uplift
when uplifted rocks reach ______ weathering erosion and deposition begin earths surface
beyond the three basic types of rock rocks can be divided into subcategoris based on composition and texture
what is the chemical makeup of a rock based on compostion
a rock that consists mostly of the mineral quarts will have a composition very similar to quarts
what do the size shape and positions of the grains that make up a rock determine the rocks texture
what factors can affect the texture of a sedimentary rock size of the grains
what factors can affect the texture of an igneous rock length of time the magma had to cool
what factor can affect the texture of a metamorphic rock pressure and tempureature the rock was exposed to
strata layers of rock
stratification the process in which sedimentary rocks are arranged in layers
deposition the prosses in which material is laid down
rock a naturaly occuring solid mixture of one or more minerals or organic mater
rock cycle the series of processesin which a rock forms changes from one type to another is destroyed and forms again by gelogical processes
erosion the process by which wind water ice or gravity transports soil and sediment from one location to another
