Document Summary
Office hours - dr. j. weaver - 3-5pm thursdays ss 5061. Geography - science that studies the relationships among parts of the earth and the interdependence of them over space. Spatial - nature/character of physical space, measurement and distribution of things within it. Physical geography - patterns/processes in our physical environment. Within it, the inputs are either stored or converted in some way: ex: car. Gets converted and such, then outputted as heat. Open systems - have an input and output. Closed systems - shut off from surrounding environment, and is self-contained. The earth and its atmosphere is an example, in terms of air, water and materials. **feedback - when an output loops and becomes an input. Ex: meltpods - areas of ice that are melted. The are a darker colour than the ice, so they absorb more sunlight, and therefore grow more.
