What characteristics of the climate in these regions would tend to limit the growth of forest?
Using the global map of biome distribution (Map T-30 in the back of the Lab Manual), the map of climate distribution (Map T-29), the maps of global temperature (Maps T-28a and T-28b), the map of global precipitation (on the inside front cover of the Lab Manual), as well as information about Köppen climate types from Exercise 23, answer the question. What will be an ideal response?
What is the elevation of this lowest location?
The question is based on this contour line map with elevations shown in feet.
• North is to the top of the map.
• Streams are shown with dashed lines.
• A graphic scale for measuring horizontal distances is shown below the map.
• Estimate elevations between contour lines to the nearest half-contour interval; assume that the top of a
hill is one-half-contour interval higher than the highest contour line shown.
