explanation[1]="A DROUGHT is a long period of time (usually months or years) when an area receives less rainfall than expected. A drought can affect one state or an entire region, and it can be temporary or long-term. Some parts of the United States, like Arizona and New Mexico, have dry weather most of the time and drought is declared only after a long period without rain. Other regions, such as New England and the Pacific Northwest, usually receive a lot of rainfall, so drought can occur after only a few months without much rain. Scientists measure drought by recording precipitation, soil moisture, and water levels in streams and rivers. Drought has a big impact on the environment and people. It causes farmland to dry up and farmers to lose their crops. Because most drinking water comes from rain, melting snow, rivers, and groundwater, our water supplies can get very low during periods of dry weather, and we must conserve water."
explanation[2]="Phoenix and Denver are located in ARID climates, and do not receive as much average rainfall as Boston and Atlanta. The average annual (yearly) rainfall for Phoenix, Arizona, is about 8 inches. Arizona has a DESERT climate, meaning it has very dry weather and receives only 10 or less inches of rain and other precipitation per year. Denver, Colorado receives about 15 inches of precipitation per year. Boston, Massachusetts, receives an average of 41 inches of precipitation per year, and Atlanta, Georgia, receives over 50 inches per year. By measuring average rainfall, scientists know how much rainfall to expect in a certain area. This helps them determine whether the area is receiving more or less rainfall than it usually does."
explanation[3]="Animals that live in deserts or areas with periods of dry weather often have to deal with hot temperatures, a lot of sunlight, and little water. Since all living things need water to survive, these animals have ADAPTATIONS such as being nocturnal (sleeping during the day and being active at night), finding other sources of water (like eating plants that hold a lot of water), or living underground. Rattlesnakes, desert bighorn sheep, and mountain lions are all adapted to living with dry weather. However, the American bullfrog is an aquatic frog, meaning that it needs to live in permanent bodies of water, such as swamps and lakes."
explanation[4]="Conifers are trees that house their seeds in cones. Pine trees are an example of a conifer. When a pine cone drops to the forest floor, it requires just the right conditions to grow, including a lot of minerals in the soil. If a wildfire sweeps through a forest and burns dead leaves and branches lying on the surface of the soil, mineral-rich soil below is exposed. Wildfires can occur within the United States, even Alaska! They are a natural process for clearing out dead brush from the forest, rejuvenating the soil, and helping new plants and trees to grow. Wildfires are common in many areas of the United States that typically have dry weather, such as the West and Southwest. They can start by lightning or human activities, such as campfires, and spread by burning dry vegetation."
explanation[5]="Conserving water is important all year long, no matter where you live. During dry weather and drought, it is especially important to do your part to save water. You can help by doing all of the tips mentioned above. Some sink faucets use between 3 and 7 gallons of water per minute, so shutting off the water while you brush your teeth can save a lot. Taking showers that are 1-2 minutes shorter will save 700 gallons a month - that’s like saving 700 milk jugs full of water! You can even save 150 gallons of water by turning off the hose in between rinses while you help to wash your family car! "
