Welcome to Year Twelve
If you are having trouble understanding any of the concepts that we are studying this year, please come and talk to us. The new WJEC syllabus for AS Level can be downloaded here However this site is extremely helpful at examining the basics of most AS and A level geography topics:
Hydrology>>>
Hydrology - I have now put some useful links online, although there will be PowerPoint slides here soon!
Here is also a glossary page to help you with some of the definitions.
Once you have completed your hydrology lessons, give this useful crossword a go to test your knowledge!
Ecosystems
Click here to view resources, case studies, glossary and book list!
Below is a list of the topic we have been covering and the associated powerpoint presentations:
1. What is an ecosystem? |
energy flows - trophic levels - biomass - gross primary productivity (GPP) - net primary productivity (NPP)
|
2. Nutrient and energy cycling |
nutrient stores and flows - nutrient cycling between soil, biomass and litter - cation exchange
|
3. Plant succession
|
psammosere - halosere - evolution of plants and soil together over time - natural and human factors - colonisation - succession - dominance - climax - diversity
|
4. Soil formation |
climate - parent material - vegetation - relief - rate of weathering - time - human interference
|
5.Effect of woodland on micro-climate |
PowerPoint Presenatation on micro-climates, ecosystems, and a woodland microclimate's influence on an ecosystem
|
6. The Nitrogen Cycle |
The Nitrogen Cycle Power point - complete with killer-bunnies® and souped up tractors - Remember how those nitrates move around the cycle!
|
7. Small scale ecosystems |
Hedgerows - Ponds - Psammoseres
|
Tectonic Hazards >>
Okay, on this site there are the EARTHQUAKE mini-site, the TSUNAMI mini-site, giving further insight as well as the VOLCANO site. and if that's not enough...
Plate Tectonics, Earthquakes and Lithosphere (including an online test) pages are available on this site.
There is also this BRILLIANT resource from the United States Geological Survey (USGS) which shows you how volcanic eruptions are predicted and then puts you in the role of Chief Scientist in a volcanic area. Will you make the right call? Click here to find out
