What processes contributed the energy that helped to melt the interior of the early Earth
collisions with asteroids
forest fires
radioactive decay
solar energy
The interior of the earth is more dense near the core than the crust because
lighter elements like silicon and oxygen form less dense compounds which float
the pull of gravity is equal for different types of elements
heavier elements like iron and nickel tend to form more dense compounds that sink
heavier elements tend to float
Scientists define the layers of the earth based on differences in
density
Whether the rocks are rigid or can flow
distance from the center of the earth
temperature
chemical composition
For each characteristic. click on the type of Seismic wave which best fits it.
P-Wave
S-wave
Arrives first
Moves through all layers of the earth
Can only move through liquid layers
Can travel through the outer boundary
has different speeds in different layers
What does analysis of seismic waves reveal about the interior of the earth.
