... plates. Be sure to explain where the energy comes from to make this process happen. The inner core is so hot that it heats up the other layers. The “puttylike” layer of the asthenosphere slowly moves – as particles get heated from core they spread out & become less dense – and they rise. They then c ...

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.
