Worksheet time: 30mins
Which of the following apply to p-waves? (choose ALL that apply)
compressional waves
travel through solids, liquids, and gases
only travel through solids
fastest moving seismic waves
shear waves
Where is heat and pressure the greatest in the Earth?
crust
mantle
outer core
inner core
How have scientists been able to infer the internal structure of Earth without being able to directly observe inside the Earth?
Scientists analyze how earthquake waves move throught Earth's interior.
Scientists use satellite radar and sonar technologies to map Earth's internal layers.
Scientists make educated guesses about Earth's internal structure based on previous hypothesis.
Scientists study different types of rocks from many different locations on Earth's surface.
What kind of seismic wave is being modeled by the slinky?
p-waves
s-waves
What kind of seismic wave is being modeled by the rope?
p-waves
s-waves
Why don't any s-waves travel through Earth's core?
the outer core is liquid and s-waves can't travel through liquids
the outer core is solid, and s-waves can't travel through solids
the outer core is metallic and s-waves can't travel through metals
the outer core is very hot, and s-waves can't travel through hot materials
Which 3 things increase as depth increases into the Earth?
time
Pressure
temperature
density
Why is the core more dense than the mantle or crust?
It has more aluminum
it has more iron
it has more tin
it has more basalt
What processes causes tectonic plates move?
mountain building
earthquakes
convection currents
water cycle
subduction zones
What phenomena takes place that results in the formation of new crust at mid-ocean ridges?
Earthquakes
Inner Core turbulence
plate tectonics
erosion of mountain ridges
magma rising to the surface
Choose the statement that is true:
Oceanic crust is thinner than Continental Crust and denser than Continental Crust
Oceanic crust is thicker than Continental Crust and denser than Continental Crust
Continential crust is thinner than OceanicCrust and denser than Oceanic Crust
Continental crust is thicker than Oceanic Crust and denser than Oceanic Crust
What are the sources of heat within the Earth? (multi-select)
