Much of the geological activity at the surface of the Earth takes place at the boundaries between

• Tectonic plates

• Seismic Waves
• Earthquakes
• Volcanic Eruptions

Scientist can infer about the components of each layer of the Earth based upon measurements using seismic waves because

• the pressure inside the Earth decreases with depth

• of the moon

• of gravity

• seismic waves change speed and direction as they travel through different materials
