From the study of seismic wave refraction and reflection, scientists infer Earth’s internal structure by locating boundaries, or discontinuities, in its composition and physical properties. Pronounced compositional ...

Physical oceanography
Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters.Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanographies.
