... If there were no oceans on Earth, the air temperature could vary from above 100°C to below ⫺100°C in a single day! Such large temperature changes could cause a lot of severe weather. Life as we know it could not exist in these conditions. The ocean can also affect the climate of different areas. Rem ...

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.
