What Are Earthquakes?

The earthquakes that happen at convergent boundaries can be very strong because so much pressure is produced. When one plate ...

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.
