Using Map T-22b, the “SP Mountain, Arizona,” quadrangle (scale 1:24,000; contour interval 40 feet), calculate the gradient of SP Mountain (35°34'56"N, 111°37'55"W) from the north base of the cone (at the 6200' contour) toward the crater rim. On the edge of a piece of paper measure out a distance of 0.2 miles using the graphic map scale, and then determine the elevation change over that distance.
In this problem, you will compute the gradients of Mauna Loa in Hawai‘i, Mount Vsevidof in Alaska, and SP Mountain in Arizona. (You may also determine the elevation changes and distances needed to calculate these gradients by using Google Earth™.) The recommended starting point and distance to measure are given for all three volcanoes.
If surface pressure readings were plotted on weather maps, they would give a false representation of the atmosphere because
A) high elevations have higher surface pressures than low elevations, even if the sea-level pressures are the same B) high elevations have lower surface pressures than low elevations, even if the sea-level pressures are the same C) the surface pressure at high elevations is often greater than sea-level pressure D) the surface pressure at high elevations is often the same as sea-level pressure
The general chemical equation for photosynthesis is shown below. Through this reaction, is the carbon oxidized or reduced? How can you tell? 6 CO2 + 6H2O ? C6H12O6 + 6 O2
A. Reduced, since in carbon dioxide there are two oxygen atoms for every one carbon, but within the product, C6H12O6, (glucose), there is only one oxygen for every one carbon. B. Oxidized, since carbon is in the +4 oxidation state in CO2 but in the +6 oxidation state in the product, C6H12O6, glucose. C. Neither, since carbon does not change its oxidation state and is neither oxidized nor reduced. D. Both, since the carbon atoms within the glucose molecules display two different charge states.
Reclamation bond money is routinely collected from mining companies with the idea that this money
will insure that the mined areas will be cleaned up and made safe once mining ceases? What actually happens when a mining operation goes bankrupt? Who ends up paying the bill? What will be an ideal response?
