Transverse waves are a type of wave in which the particles of the medium move perpendicular to the direction of the wave. This means that the oscillation of the particles is side to side or up and down, rather than back and forth. This type of wave is commonly observed in various natural phenomena such as electromagnetic waves, lightwaves, and seismic S (secondary) waves.
Develop and use models of Earth’s interior composition to illustrate the resulting magnetic field (e.g., magnetic poles) and to explain its measureable effects (e.g., protection from cosmic radiation).
