Rock Platforms: Subtidal Zone
The subtidal zone generally remains submerged except at extreme low tides.
For each physical factor presented below, indicate which of them create challenges for organisms in the subtidal zone by selecting ‘Yes’ or ‘No’:
Temperature
Yes
No

Well. While water temperature correlated with latitude affects the type of organisms found in the zone, within each climatic region the temperature is relatively stable. Try again.
This is true. The water remains a more constant temperature than those areas of the shoreline which are periodically submerged and expose.
