Igneous Rocks
Can all rocks become igneous?
Yes
These are the two processes that form Sediments
What is Weathering and Erosion.
This is how metamorphic rocks form
What is when existing rocks of any type are pushed deep within the earth and are exposed to extreme amounts heat and pressure.
This changes a Sedimentary rock into a metamorphic rock
What is heating and pressure?
2 ways Metamorphic rock is classified
Foliated vs Non-foliated/Texture
This process makes an igneous rock
What is melting to magma to cooling and crystallization?
This forms clastic-sedimentary rocks
What is Pre-existed rock cemented together
This is how we describe the texture if crystals are obvious
What is coarse grained
This turns a Metamorphic rock into a Sedimentary rock.
What is erosion to sediments to burial?
Two things that happened in intrusive igneous
Magma cools slowly and larger crystals form
These are the things people look at when identifying Igneous Rocks
What is Texture and color?
This is what it means when a sedimentary rock has coarse texture
Rock is composed of of large obvious particles
This is what it means when a rock is foliated.
What is the rock cleaves along their layers.
This turns an Igneous rock into a Sedimentary rock.
What is erosion to sediments to burial?
3 things that happen in extrusive rocks
Lava cools quickly, small or no crystals form, have vesicles and contain air bubbles
These are the 4 textures of an Igneous Rock
What is Pyroclastic, Glassy or vitreous, fine grained, and Coarse
This is what it means when a Sedimentary Rock has a Fine texture
What is Color is uniform and there is no visible sediments
This is what a parent rock is
What is the rock a metamorphic rock was before it was exposed to extreme amounts of heat and pressure
What turns an Igneous rock into a Metamorphic rock.
What is intense heating and pressure
4 types of Sedimentary rock sizes
Boulders/cobble stones/sand/clay
This tells if an Igneous Rock is intrusive or extrusive.
What is intrusive is uniform and extrusive is coarse?
These are the tree types of Sedimentary rocks.
What is chemical, organic, and clastic
This is the parent rock for Schist
What is Phyllite.
What is the Rock Cycle?
What do geologists call coarse texture?
