Its getting hot in here!
My magma has lots of children, some were born inside, some were born outside.
igneous rock
We lava this molten material from which igneous rock is formed below the surface.
magma
As more sediment is deposited in an area, the bottom layers are subjected to increasing pressure and then glued together. These conditions cause this to happen
lithification
Metamorphic rock can be created by heat from this igneous invader.
intrusion
Rock Cycle
The process of changing and remaking rocks.
This is the type of magma that contains the highest amount of silica.
What is Rhyolitic.
An Igneous rocks form when magma cools and crystallizes below Earth’s surface. This causes the rock to form slowly, grow large crystals and creates a rock with low density.
Intrusive igneous rock
These types of sedimentary rocks form when rock fragments are compacted and cemented together.
Clastic
In order for any rock to change into a different kind of rock it needs to be exposed to one of these three types of metamorphism.
regional, contact, and hydrothermal
Igneous rock is transformed into metamorphic rock by this...
Heat and/or pressure
These are the four main factors involved in the formation of magma.
1. temperature
2. pressure
3. water content
4. mineral content of the crust or mantle.
Dark rocks made of silicate minerals like Olivine, pyroxene, amphibole are this type of rock.
Ferromagnesian
This is the percentage of open spaces between grains in a rock.
Porosity
This type of metamorphic rock texture could be compared to a prisoners wardrobe.
Banded
This igneous rock texture has air pockets
vesicular
Magma is often a slushy mix of crystals and molten rock, because of this.
Minerals found in igneous rocks have different melting points and not all parts of a rock melt at the same temperature.
This term refers to igneous rocks with silica content typical of granite and rhyolite?
Felsic
I was a leaf on a tall tree surrounded by shallow water. After I fell into the water and sank to the bottom I was covered by more leaves. Over time I was squeezed into this type of sedimentary rock.
Bioclastic Sedimentary Rocks (organic)
examples of these kind of metamorphic rocks are quartzite and marble
non-foliated
Clay sized particles that are cemented and compacted together form shale. that same shale rock gets squeezed by lots of pressure to become this..
slate
This is molten rock that is higher in ferromagnesian minerals and usually forms at higher temperatures
Basaltic Magma
When a basaltic liquid first starts to crystallize the first mineral in the Continuous Reaction Series to form is
olivine
The important difference in the clastic sedimentary rocks types -- conglomerate, sandstone, shale and siltstone -- is:
sediment size
When very hot water reacts with rock and alters its chemical and mineral composition
Hydrothermal metamorphism
Minerals make up rocks, but we classify rocks based on this....
How they are formed
