The layer below the crust, much thicker and made of hot, semi-solid rock that can flow slowly is called .

• Crust
• Mantle
• Outer Core
• Lithosphere

The process where gravity pulls heavier materials to the center of a planet, creating layers inside.

• Radioactive Decay

• Planetary Differentiation

• Seismic Energy

A type of seismic wave, can travel only through solids, and moves in a side to side motion

• Seismic Waves

• Convection Currents

• P-Waves
• S-Waves

Why do denser materials sink to the core of a planet?

• They are lighter than other materials

• Gravity pulls them toward the center

• They are attracted to the Sun

• They cool faster than less dense materials.
