Rock Forming Mineral
|
The common minerals that make up most of the rocks in Earth's surface
|
|
|
Granite
|
A usually light colored igneous rock found in the conitental crust
|
|
|
Basalt
|
A dark, dense igneous rock found in the oceanic crust.
|
|
|
Grains
|
Gives a rock its texture
|
|
|
Texture
|
The look and feel of a rocks surface detrimined by the size , shape, and pattern of its grains
|
|
|
Igneous Rock
|
A type of rock that forms from the cooling of magma or lava.
|
|
|
Sedimentary Rock
|
A type of rock that forms from the fragments of rock or the remains of animals and plants cemented togethor.
|
|
|
Metamorphic Rock
|
A tpye of rock that is formed from an excising rock changed by heat, pressure, or chemical recations.
|
|
|
Sediment
|
Small, solid piecies of material that came from rocks or living oraginisms, Earth materials deposited by erosion.
|
|
|
Erosion
1 |
The destructive process in which water, wind, or gravity lossens and carries away fragments of rock.
|
|
|
Deposition
2 |
Process which a sediment is laid down in new locations.
|
|
|
Compaction
3 |
Process which sediments are pressed togethor under their own weight.
|
|
|
Cementation
4 |
Process which dissolved minerals crystallize and "glue" particles of sediment togethor in one mass.
|
|
|
Orangic Rock
|
A type of sedimentary rock that forms from the remains of oraginisms depositied in thick layers.
ex: coal,limestone |
|
|
Clastic Rock
|
A tpye of sedimentary rock that forms when rock fragments are squeezed togethor under high pressure.
ex:conglomerate, breecia, sandstone, and shale. |
|
|
Chemical Rock
|
A tpye of sedimentary rock that forms when minerals crystallize in a soulution.
ex:rock salt,tufa limestone |
|
|
Extrusive Rock
|
A tpye of igneous rock that forms from lava on Earths surface.
ex: basalt, obsidion |
|
|
Intrusive Rock
|
A tpye on igneous rock that forms from harden magma underground.
ex: granite |
|
|
Silica
|
A material that is formed from elements oxygen and silica.
ex: high silica-light rock low silica-dark rock |
|
|
Weathering
|
The chemical and pysical process that breaks down rock on Earths surface.
|
|
|
Abrasion
|
The grinding away rock by other rock particles carried by water, ice, wind
|
|
|
Mechanical Weathering
|
The type of weathering in which rock is pysically broken into smaller pieces.
Causes: freezeing and thrawing release of pressure plant growth animal actions abrasion |
|
|
Chemical Weathering
|
The process that breaks down rock through chemical changes.
Causes: water actions oxygen cardon dioxide acid rain living oraginisms |
|
|
What detrimines how fast weathering occurs?
|
climate
type of rock |
|
|
How does weathering and erosion affect Earths surface?
|
They wear down and carry away rocks.
|
|
|
What charactics are used to classife igneous rock?
|
mineral compostion, texture, origin
|
|
|
What are the uses of igneous rock?
|
buliding materials and tools
|
|
|
Ice wedging
|
The process that splits rock when water seeps into it and freezes and expands it.
|
|
|
Permable
|
charactic of a material that is full of tiny connecting air spaces that water can seep through.
|
|
|
oxidion
|
forms rust
|
|
|
Rock Cycle
|
Series of processes on Earths surface, crust, and mantle that slowly changes rocks from one kind to another.
|
