Chapter Seven. Most of the year the desert looks lifeless.. But when rainy season comes, the land explodes with life.. Plants and animals hurry to feed, grow and reproduce.. When the rain is done life seems to disappear again, until the next rainy season.. By: Ethan Thimmesch and Eli Bailey. Deserts on earth. Deserts in America. The deserts in America are very hot and dry. There are many different herbivores, carnivores and producers in the desert.. Average rainfall . : . Global Food Waste Prevention. Düsseldorf.

Deserts are all over the world but not in Europe.Not all deserts are sandy. The Antarctica desert is the biggest ice desert in the world.The Sahara desert is the biggest sandy desert in the world.. DESERTS. RECEIVE LITTLE RAIN – 10-25 cm per year. SOIL IS RICH IN MINERALS – but poor in organic material (nutrients) because there is NO LEACHING – rain that carries minerals deeper into the soil. Marshall . Plumley. Dmitriy. . Adamia. What is a Desert?. Deserts cover over 1/5 of Earth’s surface . Less than 50cm of precipitation annually. Some deserts receive less than 1.5cm . Very little/no vegetation. HOT . or . COLD. . But they are all very . DRY. . All deserts have more evaporation then rainfall.. Deserts cover 20-35% of the Earth’s land surface, and 25% of the world’s people.. ANTARCTICA is actually a large desert. There are four major types of deserts. There are four major types of deserts . Hot and Dry. Semiarid.  Coastal. Cold. Semiarid. The summers are moderately long and dry, while the winters normally bring little rainfall. Summer temperatures usually average between 69-80° F.. Deserts Adiabatic Warming and Cooling Warm, moist air masses forced up and over mountains experience decreasing atmospheric pressure and, as a result, expand. This process causes the expanding air mass to release a portion of its latent heat, resulting in a decrease in air temperature. This is called adiabatic cooling. Depending on the height to which the air is forced the air mass temperature may drop below the dew point, resulting in the formation of water droplets and precipitation in the form of rain or snow. As a result, when the air mass reaches the summit, it is cold and dry. Crossing the summit, the air mass descends and compresses. This produces a corresponding increase in atmospheric pressure and, as descent continues, the compressing air mass begin to warm. This is a called adiabatic warming. However, because the moisture was released during the cooling stage, the descending air mass is warm and dry. If sufficient moisture is removed the descending air mass could be dry enough to create a rain shadow effect where precipitation is much lower than surrounding areas. In some cases a rain shadow desert can form. Most magazines have a bifurcate . structure:. Creative Engine (Editorial and Art).
