Question 1

1.

What processes contributed the energy that helped to melt the interior of the early Earth

collisions with asteroids

forest fires

radioactive decay

solar energy

Question 3

3.

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

Question 4

4.

Scientists define the layers of the earth based on differences in

density

Whether the rocks are rigid or can flow

 The asthenosphere is the part of the _________________ that can . The part of the _________________ that touches the crust is part of the ________________  and is __________

What purpose do high-temperature and high-pressure experiments serve in studying Earth's interior?

Question 10

10.

For each characteristic. click on the type of Seismic wave which best fits it.

Question 11

11.

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

distance from the center of the earth

temperature

chemical composition

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
