Rocks
This type of Igneous rock most likely has pores (holes) in it and is not very dense
What is Extrusive Igneous Rock
This rock forms by heat and pressure applied to an existing rock.
What is Metamorphic
This is the type of luster that reflects light resembling a polished metal surface.
What is Metallic.
This type of igneous rock forms following a volcanic eruption.
Extrusive igneous rock.
This type of rock is most likely to have fossils imprinted on it.
What is Sedimentary rock.
This rock forms by magma/lava cooling and hardening.
What is Igneous
These two forces create metamorphic rocks.
Heat and Pressure
This is the state of matter for all minerals.
This is used to determine the hardness of a mineral.
What is the Mohs Hardness Scale.
This metamorphic rock is shale the protolith for
What is Slate.
This type of rock would be formed when sediments are deposited, compacted, and cemented together.
What is Sedimentary Rock.
The crystal of an igneous rock that formed from lava cooling slowly would be this size.
What is large.
The property that states - all minerals must be made in nature and they can not be man-made - is called this.
What is Naturally Occuring.
This is how a rock forms that has large crystals and is relatively dense.
What is - magma cools slowly beneath the Earth's surface.
This can be inferred about Pennsylvania's history due to the large deposits of limestone throughout the state.
What is PA used to be a shallow sea.
This rock forms by sediment compacting and cementing together.
What is Sedimentary.
This type of sedimentary rock forms when sediments get compacted and cemented together.
What is clastic sedimentary rock.
This is the streak of a mineral.
What is the color of the mineral powder.
When lava cools too quickly for an extrusive igneous rock, these do NOT form.
What are crystals.
The protplith of the metamorphic rock quartzite is this.
What is sandstone.
This is the process that breaks rock down into smaller pieces.
What is weathering.
This type of rock forms when an existing rock is subjected to extreme heat and pressure.
What is metamorphic rock.
This is how the density of a mineral is determined.
What is by the Mass and Volume.
These are the pre-existing features found in nature that forms limestone.
What are coral reefs.
This would be the color of an igneous rock that is formed from magma and has a high amount of the element Silica.
What is light colored.
