Igneous rock
Is Igneous rock Extrusive or Intrusive.
The majority of igneous rocks are Intrusive.
What are the tree types of Sedimentary rock
Clastic Rock
Chemical Rock
Organic Rock
The two kinds of Metamorphic Rock
Foliated and Non-Foliated
How to make a Gneiss rock
The most common path begins with shale, which is a sedimentary rock. Regional metamorphism can transform shale into slate, then phyllite, then schist, and finally into gneiss.
Rock
A combination of one or more minerals or organic matter.
True or False: Most granite has a mixture of quartz, mica, and feldspar
True
Forms when sediment is deposited, compacted, or cemented together.
What might happen to an Igneous rock that is exposed to high temperatures and pressure
It will turn into a Metamorphic rock
How to make Shale
Shale forms via compaction from particles in slow or quiet water, such as river deltas, lakes, swamps, or the ocean floor. Heavier particles sink and form sandstone and limestone, while clay and fine silt remain suspended in water. Over time, compressed sandstone and limestone become shale.
Composition
The minerals or organic matter that a rock contains.
What is one of the types of Igneous
Intrusive rock
True or False:
Sedimentary rocks that are made up of large pebbles and stones have a coarse-grained texture
True
Suppose a metamorphic rock is exposed to weathering and erosion what would result from this type of exposure
It will break down and turn into Sediment
How to make Diorite
Diorite is a course-grained igneous rock that forms when magma rich in silica cools slowly deep within the Earth's crust.
Texture
The size, shape, and positions of the grains that make up a rocks texture
What is the other type of Igneous rock
Extrusive rock
What is Chemical Sedimentary rock is
It is when water, usually seawater evaporates
Explain what Foliated means
Occurs when pressure causes the mineral grains in a rock to realign to form parallel bands. Minerals may be squeezed into sheet-like layers.
How to make Marble
Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz. It forms when a quartz-rich sandstone is altered by the heat, pressure, and chemical activity of metamorphism.
All rocks can be
Considered to be mixtures of minerals.
How does the cooling rate of magma or lava affect the texture of the Igneous rock that forms
The faster it cools the smaller or no crystals there are. The slower the crystals cool the larger they are.
Explain what a Organic rock is
An Organic rock is a rock that forms from the remains, or fossils of once-living plants or animals.
Explain what Non-foliated means
Mineral grains that are aligned in planes or bands. During metamorphism, minerals grains or crystals may change size or shape, and some may change into another mineral.
How to make Sandstone
Must be naturally occurring, solid, inorganic, definite chemical composition, crystal structure
