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.

the depth at which the layer starts

the age of each layer

whether the layers are solid or liquid

the chemical composition of each layer
