Earth's Interior
A seismic wave is an example of what type of evidence
Indirect evidence
What is the equation used to find density?
Metamorphic rock forms as a result of changes in heat and ____________ in the Earth's surface.
Pressure
What process is responsible for causing a column of rock to form?
Weathering
What is a naturally occurring solid that can form by inorganic processes and has a crystal structure, and definite chemical composition.
A mineral
What is the thinnest layer of the Earth?
True or false- There are more than 5000 types of minerals.
True
The cementing of small pieces of rock and shells causes ________________ to form.
Sedimentary rocks
What is a step in the process of rock changing from sedimentary to igneous?
Melting
Rock that forms from cooled lava or magma.
Igneous rock
What drives convection currents?
Heat from the core and the mantle
List 3 properties that geologists use to identify and describe minerals.
Answers will vary: Luster, streak, color hardness, density, cleavage, fracture, and structure.
Name the 3 main types of rocks.
Igneous, metamorphic and sedimentary.
What processes can recycle sedimentary rock into sediment?
Weathering and erosion
This is formed when a rock is changed by heat or pressure, or by chemical reactions.
Metamorphic rock
True or false- The outer core is solid.
False
Metallic, glossy, earthy and pearly are all words to describe a minerals what?
Luster
How is igneous rock formed?
From the cooling of melted rock (lava and magma)
What causes sedimentary rock to change to metamorphic rock?
This forms when small particles of rock or remains of plants and animals are pressed and cemented together.
Sedimentary rock
Name the layers of the Earth starting with the innermost layer and moving outward
Inner core, outer core, mantle, crust
True or false- Naturally occurring, solid, forms by organic processes, crystal structure and definite chemical composition are the characteristics needed to be a mineral.
False- needs to be formed by inorganic process
To describe rocks, geologists observe what 3 things?
What role does plate tectonics play in the rock cycle?
It plays a major role. Moving plates help drive the rock cycle by helping to form magma. Without magma, there would not be any igneous rocks.
What is the series of processes that occur on Earth's surface and in the crust and mantle that slowly change rock from one kind to another.
