Rock Cycle
What is the change from an igneous to a metamorphic
Heat and pressure
what are the three sub classifications of metamorphic rocks
chemical, clastic, organic
what are the two sub-classifications of sedimentary rocks
foliated and nonaffiliated
what are the two sub classification of igneous rocks
extrusive and intrusive
what is humus used good for
humus is a thing that is good for the soil. A lot of humus means fertile soil
how do you get from sediments to sedimentry
how do the two types metamorphic rocks
foliated formed by pressure
Nonfoliated formed by heat low pressure
what is clastic rock made of...
clastic made of weathering debris
what is intrusive and extrusive igneous rock made of
extrusive is made of lava
intrusive is made of magma
what is pore space
Another good thing for the soil that involves extra space that is used for water and air. Helps plants grow
how do you get a sedimentary rock to a metamorphic
heat and pressure
How are metamorphic created
metamorphic rocks are created by magma. There also created when the igneous and the metamorphic get affected by the change of heat and pressure
what are organic sedimentary rocks made of
fossils and bones of animals
how are igneous rock formed
by molten magma on the surface and also molten rocks
what color is soil for it to be fertile
soil is usually a darker color
Any rock that goes into sediments has to go through the process of...
weathering and erosionn
whats the difference between foliated and nonfoliated metamorphic rock
foliated have layer banded appearance and nonfoliated don't
how are sedimentary rocks formed
sedimentary rocks formed when sediments cement and compact to form a seminary rock
what is the difference between extrusive intrusive igneous rocks
extrusive cools and solidifies cooler intrusive
what is the difference between magma and lava
magma is underground and lava is above ground
whats the only way to get to an igneous
by melting metamorphic rock to magma and then colling to igneous
what are some types of metamorphic rocks
non folliated: marble,quartize
Folliated: slate,gneiss,schist phylite
etc.
what are some types of sedimentary rocks
clastic: limestones and sandstone.
chemical: halite
organic seminary: coal
etc.
what are some types of igneous rocks
intrusive: granite
Extrusive: obsidian and basalt
etc.
what number is considered the acidic soil and fertile soil
below 7 acidic
above 7 fertile
