Document Summary

Be able to identify these on a map: be able to identify and know the definitions of the different ways that wind transports sediment in deserts. Where do we find loess: know the dune diagram, and be able to identify different kinds of dunes. You should also be familiar with the conditions under which particular kinds of dunes will form. Deserts and steppes cover ____________% of the land surface on earth (42 million square kilometers). We define these dry climate zones as areas where yearly precipitation is not as great as the loss of water by evaporation. ____________________________________: extremely arid, driest of the dry climate zones. Where we find deserts: primarily between _______________ n and s (concentrated at the tropic of.
