DESERT - Essay Example Deserts can be found across the world but the geographical areas are classified in four regions. The subtropics are the ones where most of the deserts around the world are found as these regions are immensely dry and their dryness is usually because of the circulation of hot and dry atmosphere. The second is the middle-latitude continental interiors which are arid regions and their aridity is mainly due to their far distances from the oceans. The deserts in these regions are cloudless and mostly have average temperatures of below-freezing in winters. The third is the leeward sides of mountains which covers the region of Southwest America. The clouds release the moisture on windward slopes of mountains, leaving dry air on the leeward side. The last are coastal areas where deserts are formed with the cold currents as they stabilize the air over the shore (Greenberger 132). The desert biome has many unique characteristics that make it different from rest of the biomes. The temperature at first is the most defining characteristic of a desert. The deserts are usually warm in the day as compared to nights but the differences of temperatures are very drastic. The average temperature at day time in a desert would be 100Â °F while at night it would be 25Â °F (Greenberger 133). This is a large temperature difference and it is because the moisture is very little in the desert air. Other unique characteristics are the lack of plantation and animal life in deserts. The plants which grow in deserts are unique such as the cactus which require low amount of water to survive. One of the major environmental problems in deserts is desertification which is an issue in the entire world. The main cause of desertification is humanly activities due to which desert areas are expanding. Some of the human activities that increase desertification are over farming, over grazing, poor irrigation systems, mining, and digging for search of fossil fuels (Greenberger 134). People who
