Option C Extreme environments: Management and futures
14 revision questions with answers for Option C Extreme environments: Management and futures, marked SL and HL. Read them here, or play the set as a class game on the projector. Free to host, and students join with a code.
Land degradation in arid, semi-arid and dry sub-humid areas from climate variation and human activity?
- Salinisation
- Aridification
- DesertificationRight answer
- Deforestation
What this set covers
Pressures on fragile places and the responses to them are the focus. Desertification, overgrazing, transhumance, thermokarst, glacial lake outburst floods, qanats, fog harvesting, the Antarctic Treaty, shelterbelts and black carbon appear.
- Common mix-up
- Students often treat transhumance and nomadic pastoralism as the same: transhumance is a seasonal move between lowland and upland pastures, while nomads have no fixed settlement.
- Revision tip
- Choose one extreme environment and link a human pressure from this set, such as overgrazing or black carbon, to a management response that targets it.
