Earth Layers
The thickest layer of Earth's interior
what is the Mantle
the formula to calculate density
what is D=M/V
ways energy (heat) is transferred from one place to another: 3 types - conduction, convection and radiation
what is heat transfer
where does the rock cycle start?
anywhere!
the state of matter of the inner core
what is solid
This layer often gets grouped with the crust. It is the first layer in the mantle.
what is the lithosphere?
a measure of how much matter is in an object
what is mass
a type of heat transfer that happens when 2 objects make physical contact.
what is conduction
these are the only rock type that can contain fossils
what is sedimentary rock
Heat always transfers from __________ to __________.
what is warmer objects to cooler objects
As depth increases, ________, ________, and density are also increasing.
What is temperature and pressure
________ is the the measurement of how much matter of a substance is contained in a given volume
what is density
a type of heat transfer that is invisible to our eyes and is felt with NO contact
what is radiation
metamorphic rocks form when exposed to what?
intense heat and pressure
the three layers of the mantle (in order)
what is the lithosphere, asthenosphere, and the mesosphere
The reason why the mantle is constantly in motion. (Hint: we talked about this in heat transfer!)
what are convection currents
You find this by measuring the difference in water levels (must be specific)
what is the volume of an irregularly shaped object
these currents are found in the ocean, in our atmosphere controlling the weather, and even deep underground in the mantle
convection
an example of a surface event
what is weathering, erosion, or deposition
differentiate between magma and lava
magma: molten rock that is still underground
lava: molten rock that has reached the surface
The layer responsible for Earth's magnetic field (must also explain why)
What is the liquid iron outer core
1- density =1.23
2- density= 0.256
3- density= 0.123
4- density= 0.0279
Put them in order according to their densities
4 (least dense)
3
2
1 (most dense)
in order for heat transfer to occur, there must be what?
a difference in temperature
rocks that form when magma cools and crystallized outside of a volcano (must be specific)
what is an extrusive igneous rock
obsidian (black, glossy, smooth) is what type of rock?
(extrusive) igneous
