How did the Earth’s interior become separated into layers?
When the Earth was young and molten, the denser metal sank to the center while the less dense rock floated to the surface.
The layering of the Earth's interior was a result of the gravity of our Moon tugging at our planet.
The layering of the Earth's interior was a result of the Earth'd double iron core.
The layering of the Earth's interior was caused by the electrostatic forces acting on small dust particles before Earth fully cooled.
Which is true of Earth's interior?
The interior gets cooler towards the center
The interior is made up of hydrogen atoms that go through nuclear fusion
The interior gets hotter towards the center.
The interior is the same temperature as the upper crust.

How do scientists know the Earth has layers?
Drilling into the mantle

ocean waves
Which statement is INCORRECT relating how seismic waves travel?
Seismic waves are bent as they travel between different materials of various densities
Seismic waves bounce off transitions as they travel through materials with different temperatures
P waves travel parallel (vibrate back and forth) while S waves travel perpendicular (vibrate up and down)
Seismic waves travel through Earth in straight lines at constant speeds.
Choose the statement that is TRUE
