However, we won't have time to talk about those. This material is covered in your book in Chapter 4, but the coverage is very brief. The biomes have a strong spatial correspondence to the major climatic zones as well as to major soil types. Look at the maps of biomes and climate. This map shows twelve biomes.
Some treatments show as few as five or six.
Look in your text on page 69. Your text defines nine biomes. If we look at the climate map, we see that the climate patterns are similar to the patterns that the biomes form on the landscape. A map of soils would show similar patterns as well. The chart below shows another way of looking at the relationship of biomes to climate.
