Oceanography Week 8
1. What is a tidal bore?: A large wave caused by the funneling of a flood tide as it enters a long, narrow,
shallow inlet.
2. How do snails move (quickly) to find food?: Snails are slow so they use the incoming tidal current
as a ride up to the beach, using their heightened sense of smell to track down food.
3. How do flounder take advantage of the tides?: Incoming tides create a strong current. Like
snails flounders catch a tidal lift from the currents that bring them into the shallows.
4. During what moon phases do Spring tides occur?: Immediately after the new moon and
again after the full moon.
5. What special challenges does life face along a rocky coast?: Tidal currents in rocky
coastal areas can be a damaging force as the shore gets pounded by waves and strong currents.
6. How do some fish take advantage of gentle tidal currents?: Use it as a resting place
where they can ride the current without expending energy (stingrays). Also the current is useful in sweeping food by
smaller fish (demoiselle fish).
7. What is special about the tides near the equator?: The moon's gravitational pull is weaker
at the equator so the more equatorial the location the smaller the tides.
