rock cycle
why do we have events like rain, wind, and things like that
because of the suns energy
what is the rock cycle
It is a procces where rocks change from one another over time due to various earth processes.
what types of rocks can become metamorphic
what are the two types of Igneous rocks
Intrusive and extrusive
sedimentary rocks are formed by what
sediments and minerals
what are the three types of rocks
sedimentary, igneous, metamorphic
what does erosion do
Carries sediments through wind, water, gravity or other means.
how can rocks become metamorphic
by extreme heat and pressure
where do extrusive igneous rocks form
what happens to the sediments in order to become sedimentary rocks
it gets burried deep and gets compacted and cemeted
after weathering happens, what occures after that
erosion
what is litification
the compaction and cementing of sediment into a rock
what are the heat sources to make a metamorphic rock.
Magma, geothermal heat, anf friction along faults
what is an igneous rock texture like
they feel glassy and have a vesicular texture
how do the sediments get to the bottom of bodies of water
erosion
what causes weathering
wind, ice, plants, animals, and change in tempature
what is the definiton of depostion
the laying down of sediment carried by wind, flowing water, the sea or ice
Where does the pressure come from to make metamorphic rocks
weight from overlying rocks deep in the earth
how do igneous rocks form
when maga cools and forms crystals, and solidifies
where are sedimentary rocks found
at the bottom of boddies of water
this is how rocks get pressed down to the layers below the surface
by Compaction and cementation
what is the lithosphere
It is the rigid outer part of the earth
where are metamorphic rocks found
deep within the earth
where can you find igneous rocks
by erupting volcanoes
why are sedimentary rocks found in the bottom of bodies of water
because the water helps weather exsiting rock, creating sediments
