Earth's Layers
The Earth's thinnest layer.
What is the crust?
The processes that form a mineral.
What is inorganic?
What are the 3 types of rocks?
Igneous, sedimentary, and metamorphic.
Which of the following lead most directly to the production of igneous rock?
a. formation of magma
b. cementation of rock
c. weathering of rock
a. formation of magma
The part of the Earth's interior that has two distinct layers.
What is the core?
True or false: a mineral must have a crystal structure.
What is true?
Where are sedimentary rocks likely to form?
In the ocean or in another body of water.
How can an igneous rock become a metamorphic rock?
Heat in the core and the ____________ cause __________ ______________, which help to cycle material on Earth.
Heat in the core and mantle cause convection currents, which help to cycle material on Earth.
Metallic, glassy, earthy, and pearly are words that describe a mineral's _____________.
Which process acts on Earth's surface to break rocks into pieces?
What is weathering?
What is a step in the process of a rock changing from sedimentary to igneous?
Melting
Layers of the Earth from thickest to thinnest.
What are the mantle, outer core, inner core, and crust?
True or false: minerals do not have a crystal structure.
Metamorphic rock forms as a result of changes in ________ and _________ in Earth's interior.
Metamorphic rock forms as a result of changes in heat and pressure in Earth's interior.
True or false: Any type of rock can transform into another type of rock with the right conditions.
The reason that the inner core is solid and the outer core is liquid.
What is the inner core is under so much pressure that it pushes the particles into a solid?
If a substance is naturally occurring and solid but doesn't have a crystal structure or a definite chemical composition, is it a mineral?
No.
A rock sample contains tiny pieces of other rocks that are cemented together. Is it an igneous, sedimentary, or metamorphic rock? Explain.
It is a sedimentary rock, which is the type of rock that is formed from sediment that is cemented together.
How is a sedimentary rock formed?
First weather and erosion happens. Then the sediment is deposited, compacted, and cemented.
