A geographer is interested in conducting an analysis of possible spatial associations. Which of the following geospatial technologies will be especially significant in conducting this research, and why? A.
remote sensing, because it conveys information about physical changes in a location over time

B.
GIScience, because it will help the geographer conduct quantitative analysis of layered information

C.
mental mapping, because it will help the geographer analyze images

D.
volunteered geographic information, because it will help the geographer see where life expectancy is low

E.
GPS, because it will help the geographer identify locations using geotagging

If you could drill a hole straight to the center of the earth, and keep track of what the hole is going through, youwould find: a) you would go through one sort of material, and then a different, denser material, and then a still-different, still-denser material, because the planet is made of concentric layers, sort of like an onion.b) you would go through one sort of material all the way to the center, because the planet is all mixed up.c) if your hole started at the north pole, you would go through different layers of different materials, but ifyour hole started at the equator, you would go through one sort of material all the way to the center.d) if your hole started at the equator, you would go through different layers of different materials, but if yourhole started at the north pole, you would go through one sort of material all the way to the center.e) you would strike diet pepsi when you got to the center.

Extensive and unusual cold snaps have occurred here recently. is this evidence that global warming is lessening or not occurring? no—although the long-term trend is for warming, short-term weather patterns can still be variable. no—melting of glaciers and ice caps is making the oceans cooler, which can cause cold snaps. yes-- if global warming really were occurring, cold snaps wouldn’t happen. yes—due to global warming, weather patterns should be become less—not more—variable.
