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 |
