Branches of Geology
Interior of Earth:
Seismic (energy) waves travel through the earth some energy bounces off harder layers called Reflectionsome energy travels through but gets bent, changing the direction the wave is traveling called refractionsome energy is absorbed as it encounters materials Called attenuation
Allow us to model what waves show up at given locations, and when they arrive at given locations.
