Environments

 

1. You should know the following terms:

ecologic niche, ecologic community, food chain, food web, ecosystem, flora, fauna, diversity, terrestrial,

2. Explain your friend, or spouse the different climate zones and their characteristics such as tropical rain forest,  tropical desert, Polar-Arctic, tundra, evergreen coniferous forest, temperate forest, Mediterranean.

3. Be able to explain to someone and make her/hem very impressed why fossil plants are so good climate indicators?

4. You should know about marine life habitats, such as Plankton (zoo, Phyto), nekton, pelagic life, benthos.

5. Be sure, that you know how important the temperature and the salinity of seawater (normal, hypersaline and brackish). Also that the energy level of the water is important (high energy/low energy environments).

6. Freshwater environment. How good is it for life? Do we have higher diversity in a freshwater environment compare to the marine?

7. Sedimentary environments. 1. Soil environments; be sure and know what kind of difference the climate can cause in the soil development. What features would help to identify ancient soil, and why is it important?

8.Lake environments. How do we separate marine from lakes?

9. Glacial environments? What kind of sediments do you find in this environments, what other features would you use to determine an arid environment?

10. Desert and arid basins? What kind of sediments do you find in these environments, what other features would you use to determine a glacial environment?

11. Alluvial fan, braided river, meandering system. Be able to sketch them, and be able to label your drawings. What kind of sediments do you expect to see, and how do they change from alluvial fan to meandering river?

12.Transitional environments; explain prodelta, Delta front ,delta plain and the meaning of progradation. What kind of sediment do we have around deltas. Are deltas good places to find geological resources?

13. Organic reef environment. What parts does it have? (reef talus, back reef lagoon, reef flat), Atolls

14. Deep ocean. Carbonate compensation level (5000 m). What kind of sediment do we have down there?
