I've had
Feel Good Inc on loop for close to four hours while i frantically tried to mug "Slope Profile Analysis" for Physical Geography.
Yes, i was insane enough to take it up at A levels. But it's really cool; let me just regurgitate G K Gilbert's Theory of Soil Creep to annoy everyone: There is a natural downslope increment of soil, because soil formed at each point on the slope is added to be soil creeping from above. As the transport rate of soil creep is directly proportional to slope angle, the angle of the slope will likewise increase with distance from the slope crest. Hence, the slope steepens downslope to allow increasing amounts of soil to be evacuated." Makes soil sound like fire victims or something.
