Basic questions 1. Can you correctly identify lines of latitude versus longitude? a. Latitude is the horizontal line (parallels) b. Longitude is the vertical line (meridians) i. Both measured in degrees, minutes, and seconds 2. Do you have basic definitional and applied grasps of the major concepts listed above in section A? a. Location a. Absolute location- coordinate system like latitude and longitude i. This is important primarily for aspects of physical geography. b. Relative location- with respect to some other object. i. As surfers, we care about our location relative to storm systems. b. Site/Situation a. Site- take the absolute location coordinates and expands it to include natural environment, characteristics of the areas at and near the location. i. Site characteristics of Hawaii would include descriptions of the climate, geology, etc. b. Situation - almost identical to relative location. The only difference is that situation is often used to describe how a place is attached to other places through social, economic, or cultural ties. i. Hawaii became increasingly connected to the U.S. because of its military importance (military network), it was attached to the mainland through a cable (communications network), and ferry service increased (transportation network).

c. Place- similar to absolute location and site but emphasizes the human cultural landscape and its relationship to the natural landscape. d. Spatial diffusion- theory has been used either casually (informal classification) or formally (mathematically) to study how culture, infectious disease, or other phenomenon spread from one area to others. a. Carriers are the agent/medium that spread the culture trait b. barriers are aspects of the natural/cultural environment that act to block, mitigate, or redirect the spread of that culture trait. i. Expansion diffusion- occurs when the culture trait expands from an original location (site of the innovation) to other nearby locations and the most intense use continues in that original location. ii. Relocation diffusion -the use or practice of the culture trait in the original location dies out because the population with the culture trait moves (migrates) from one location to another. iii. Contagious diffusion- spreads from person-to-person through direct contact with the carrier. Because of the need for person-to-person contact contagious diffusion is most intense close to the original source of “infection” or innovation and lessens with distance from the point. Large distances / isolation are effective barriers against contagious diffusion. iv. Hierarchical diffusion- processes spread from node-to-node in a network and follow a path of the smallest network distance instead of the smallest physical distance. The network can be formal (hubs in a set of commercial airline flight plan) or informal (networks defined on similarities in culture, economic ties, class systems 1. On a geographic map, the diffusion will appear to hop from one
