Lesson 41
Marine Biomes and Estuaries
| Question | Answer |
|---|---|
| Euphotic zone | the portion of the ocean into which light can penetrate fully |
| Intertidal zone | shallow shoreline that constantly changes with the tides |
| Pelagic zone | shallowest area of the open ocean |
| Neritic sub-zone | shallowest pelagic sub-zone--sunlight penetrates completely |
| Epipelagic sub-zone | brightly lit second pelagic sub-zone that contains significant photosynthetic algae |
| Mesopelagic sub-zone | sub-zone- darker third pelagic sub-zone, contains many of the carnivorous ocean life and also animals that have special adaptive features to exist in dark conditions |
| Bathypelagic sub-zone | deepest pelagic sub-zone, complete darkness |
| Benthic zone | ocean floor, contains continental shelf and continental slope |
| Continental shelf | extension of the land mass into the ocean, located in the benthic zone |
| Continental slope | sharp drop-off from the continental shelf into the deeper areas of the ocean, located in the benthic zone |
| Abyssal zone | ocean floor in the deepest sections of the ocean, contains rifts and hydrothermal vents |
| Rifts | cracks in the ocean floor, formed by shifting tectonic plates |
| Coral reef | contains the exoskeletons of coral and algae, they appear in warm shallow waters, especially in the areas around land masses |
| Estuaries | bays where a river flows into a marine body |
