| Question | Answer |
|---|---|
| The Coriolis effect refers to | the apparent deflection of the path of air currents and ocean currents that results from the earth and atmosphere and ocean water moving at different speeds. |
| When the sun, moon, and earth are all in a line_tides occur | spring |
| Ocean currents are produced by | Winds |
| Carbon dioxide gas is produced by living organisms during the process of | Respiration |
| The restoring force for large waves is | gravity |
| _are periodic changes in sea level due to the gravitional pull of the moon and the sun. | winds |
| The relativity high boiling and freezing points of water are due to | the ability of water molecules to form hydrogen bonds |
| A zone that exhibits a rapid change in temperature with depth is called a | thermocline. |
| Compounds that release hydrogen ions when they dissolve in water are called | acid |
| Long-period, uniform waves that can travel for thousands of kilometers are called | breakers |
| The apparent deflection of the path of air | Coriolis effect |
| Sudden movements of the earths crust that produce earthquakes. | Tsunami |
| Where salinity increases with depth to about 1,000 meters. | Halocline |
| Periodic changes in water level that occur along coastlines | Tides |
| Force that causes the water to return to the undisturbed level | Restoring Force |
| Ekman Transport | the net movement of water to the 100 meter depth. |
| Breaker | when the bottom of the wave slows but it crest continues moving towards the shore at a speed faster than that of the waves. |
| Greenhouse gases | the accumulation of certain gases. |
| Gulf Stream | the biggest of these western boundaries currents moving at average speed of 2 meters per second. |
| Sverdrups | the volume of water transported in an ocean current in measure. |
| Ekman transport | The net movement of water to the 100 meter depth. |
| Breakers | When the bottom of the wave slows but it crest continues moving towards the shore at a speed faster than that of the wave. |
| Greenhouse gases | The accumulation of certain gases. |
| Adsorption | the process responsible for removing the largest amount of salt however involves ions sticking to the surface of the fine particles |
| Salinity | The concentration of salt in a given volume of water |
| Buffer | A substance that can maintain PH of a solution at relativity constant point. |
| Slack Water | during the changes of tide from high to low or low to high |
| Ions | salt crystal are made of individually charged particles |
| Ekman spiral | spiral flow of water |
| Vertical mixing | Any process that increases the density of surface water will cause vertical movement of the water |
| Alkaline | Substance that can bind hydrogen ions and remove them from a solution. |
| Plungers | Breaker formed when the beach slope is steep |
| Spiller | Breakers formed when the beach slope is steep. |
| Gyres | The position of the continents and the features of the ocean basin interfere with the continues flows of water and contributes to the deflection of currents so that water flows in a circular pattern around the edges of an ocean basin. |
| How does a sponges body structure affect its size? | by its ability to circulate water through its body |
| What are a boring sponges role in the enviroment? | they make their own habitat by boring into coral or dead shells |
| What are advantages bilateral symmetry have? | they are more in active lifestyles by giving concentration for sense organs and they also have a more streamlined body. |
| What are ecological contribution burrowing organisms have? | they form s habitat for thousands of organisms. |
| What is the ecological role of meiofauna? | they adapt to small space between sediment particles and they use cilia to crawl or glide and they leave a track of mucus. |
| How do sponges feed and reproduce? | Feed by filter feed when they take food from water and reproduce asexually or sexually. Reproduce asexually by budding. |
| How are nematocyst activated in cniderians? | stinging cells are activated when the capsule in the cellos open by the nematocyst when it is discharged. |
| what is the difference between selective desposit feeders and nonselective deposit feeders? | nonselective deposit feeders injest both organical minerals and digest organic minerals while selective deposit feeders separate organic material and mineral and only injest organic material. |
| How does radial symmetry have more advantages than sessile organisms? | Radial symmetry allows them to meet and respond to their environment equally well from all sides. |
| What is the difference between hydrozoans an scypozoans? | Hydrozoans medusa are release into theater when they are mature while scypozoan medusa are release into the water when they are immature. |
| Meiofauna | Tiny organisms that are adapted in the spaces between sediment particles |
| Stylet | A hard, sharp point and the end of an organ |
| nematocyst | the stinging organelle found with tn the stinging cell of cniderian |
| Nematodes | A round wormlike animal that belongs to the phylum Nematoda |
| Hydroid | A colonial organism belonging to the cnidarian class Hydrozoa. |
