The first point to learn in this
module is that we choose to study one type of geomorphic environment:
OUR CHOSEN GEOMORPHIC ENVIRONMENT IS GLACIAL. The exam questions will not refer to GLACIATED areas they will say a 'named geomorphic environment' by which they mean 'GLACIAL' for all schools who have studied this! |
|
| Generalisation A: Geomorphological processes are influenced by atmospheric processes, globally and within a region. A study of the processes involved in a geomorphic environment can be undertaken through the systems approach. |
|
|
| Key Idea 1: At a global scale, the nature of landform systems varies and is influenced by differing atmospheric processes and conditions. Thus the relative importance of weathering, water wind and ice produces distinct geomorphic environments i.e. glacial, arid or coastal geomorphic environments. |  |
|
| Key Idea 2: The distinctive landforms within ONE geomorphic environment (i.e. GLACIAL) are the product of the processes of weathering, erosion, transport and deposition. these processes also interact with geology. |  |
|
| Key Idea 3:
Landforms in a geomorphic Environment exist in a sate of dynamic
equilibrium.
(a) High energy events, separated by longer periods of relative stability and slow change, are important in landform evolution. These events could be caused by changing atmospheric conditions.
|
|
|
| (b) Landforms within the chosen geomorphic environment (i.e. GLACIAL) may show the effects of modification by other geomorphological agents or processes. |
