True or False: Scientists have been able to make observations beneath Earth's crust.
TRUE:
Those observations come from seismic waves
TRUE:
Those observations come from rock samples of the asthenosphere
FALSE:
Scientists have not been able to take samples beneath Earth's crust
FALSE:
Scientists can only make guesses about Earth's interior
Select all that are true about P-waves
P stands for primary
They are slower than S waves
They travel as longitudinal waves
They cannot travel through liquids
Select all that are true about s-waves
They are slower than P waves
S stands for stationary
They travel as transverse waves
They cannot travel through liquids
How many major layers are there in Earth's interior?
2
3
4
6
What is Earth's inner core like? Select all that are true:
Solid metal ball
About as hot as the surface of the sun
Intensely pressurized
pretty dangerous, lots of weird fungi and dinosaurs, don't recommend for vacation.
Scientists know that Earth's outer core is liquid because....
P-waves can't travel through it
S-waves can't travel through it
They are just guessing
They've taken direct samples
What is the most common element in earth's inner and outer core?
iron
hydrogen
potassium
gold
Which layer of Earth's interior generates its magnetic field?
Mantle
Crust
Outer core
Inner core
This layer is solid to semi-solid and is slowly circulating because of convection
Mantle
Crust
Inner core
Outer core
The asthenosphere has a consistency much like...
Sand on the beach
Canola oil
Carmel candy
Melted chocolate
Which of Earth's layers is defined as thin & brittle?
Crust
Mantle
Inner core
Outer core
Which layer of the Earth can be described as "plastic and flowing"?
Asthenosphere
Inner core
outer core
crust
Where do Earthquakes occur?
At the boundary between tectonic plates
Randomly across the crust
In the center of tectonic plates where there is the most mass
Under cities with heavy buildings
What kind of waves are seismic waves?
Kinetic
Mechanical
Electromagnetic
Elastic
What would happen if a p-wave were to pass from a solid to a liquid?
It would slow down because the molecules are spaced further apart.
It would speed up because it has more room to move between molecules.
It would stop because p-waves can't pass through liquids.
It would maintain a constant speed.
What would happen if an s-wave were to pass from a solid to a liquid?
It would slow down because the molecules are spaced further apart.
It would speed up because it has more room to move between molecules.
It would stop because s-waves can't pass through liquids.
It would maintain a constant speed.
