Sedimentary
What the three types of sedimentary rocks?
The three types of sedimentary rocks are clastic, biochemical, and chemical.
How do igneous rocks form?
Igneous rocks form when lava cools and crystallizes.
What is metamorphism?
Metamorphism is any process that affects the structure or composition of a rock in a solid state as a result of changes in temperature, pressure, or the addition of chemical fluids.😁
What is weathering?
The mechanical and chemical processes that change objects on Earth's surface over time
What is erosion?
Erosion is the removal of weathered material from one location to another.
How do chemical rocks from?
Chemical rocks form when minerals crystallize directly from water.
Name an example of an intrusive and extrusive rock.
An intrusive rock example is it granite and an extrusive rock example is Obsidian
Under what conditions do metamorphic rocks form?
In temperatures higher than 200 C and pressures higher than 3 kb.
How does weathering break down or change a rock?
Weathering breaks down and changes a rock by breaking it down, wearing it out, and chemically.
What is deposition?
Deposition is the layering down or setting of eroded material.
How do biochemical rocks form?
Biochemical rocks form from remains of organisms
Why are there holes in some igneous rocks?
There are holes in some igneous rock because that is where the gases escaped.
What is foliated rock?
Foliated rock contains parallel layers of flat and elongated minerals.
Why is the surface area of a rock important?
It is important because the rate of weathering depends on a rock's surface area that is exposed to the environment.
How can erosion affect the shape of sediment?
It can because rock fragments bump into each other.
What is an example of clastic rock, biochemical rock, and chemical rock?
Clastic rock example is sandstone and claystone, biochemical rock example is limestone and chalk, and chemical rock example is chert and evaporites.
How do intrusive rocks form?
Extrusive rocks forms when volcanic material erupts and cools and crystallizes on Earth's surface
What is nonfoliated rock?
Nonfoliated rock is metamorphic rocks that have grains with a random, interlocking texture.
What is the result of a rock undergoing mechanical weathering?
They rock can expand and crack.
How can erosion sort sediment?
It can because when a lot of wind comes it moves the lighter rocks ,which are usually about the same size, to a place where they stop.
What is compaction?
Compaction is the weight from layers of sediment forces out fluids and decreases space between grains.
How do intrusive rocks form?
Intrusive rocks form when magma cools underground.
What is the difference between contact metamorphism and regional metamorphism?
Contact metamorphism is when magma comes in contact with existing rock, and it's thermal energy and gases interact with the surrounding rock, forming new metamorphic rock, but regional metamorphism is the formation of metamorphic rock bodies hundreds of square kilometers in size.
How does chemical weathering change a rock?
It gets a layer of red oxide on the outside surface.
What is uplift?
The process when the Earth's surface goes up.
