AS Geography Case Studies

This is the list from class for those of you who missed it. It is nothing more than what is on the specification sheets which should be your main guide. All that I have added is the names of the particualar case studies we have chosen.

TECTONICS

1. Plate margins (3 – constructive, destructive, conservative) – landforms and hazards

2. Two contrasting tectonic events – Causes and impacts

- Bam earthquake, Iran - 2003
- San Francisco earthquake, USA - 1989

- Mt Pinatubo eruption, the Philippines - 1991
- Nevada del Ruiz, eruption, Colombia - 1985


HYDROLOGY

1. Landforms of a floodplain – River Usk (between Usk and Newport)

2. Two contrasting flood events
- Flooding on the Rhone, South of France - 2003
- Flooding in Mozamique (River Limpopo and others) Mozambique - 2000


ECOSYTEMS

1. Example of a small scale ecosystem – deciduous woodland (Rougemont Wood)
- Energy flows (pyramid diagram)
- Nutrient flows (Gersmehl’s diagram)

2. Example of a soil – Brown Earth (under deciduous woodland)

3. Example of a plant succession – A psammosere - sand dunes - (Whitford Sands, Gower)

4. Example of a plagioclimax – heather moorland (Brecon Beacons)
