3. The relatively weak, irregular current produces when the water from breaking waves is pulled back to deep water is:

Drift

An undertow

A longshore current

A rip current

7. When a river enters the ocean through a long bay, the ocean tide may rush into the river creating a surge of water called a tidal

Bore

Oscillation

Range

Flat
