 * = **Key Ideas** || **Standard 4: The Physical Setting
 * = **Standards** || * //**Performance Indicator 2.1: Explain how the atmosphere (air), hydrosphere (water), and lithosphere (land) interact, evolve and change.**//
 * **2.1a: Nearly all the atmosphere is confined to a thin shell surrounding Earth. The atmosphere is a mixture of gases, including nitrogen and oxygen with small amounts of water vapor, carbon dioxide, and other trace gases. The atmosphere is stratified into layers, each having distinct properties. Nearly all weather occurs in the lowest layer of the atmosphere.**
 * **2.1b: As altitude increases, air pressure decreases.**
 * **2.1c: The majority of the lithosphere is covered by a relatively thin layer of water called the hydrosphere.**
 * //**Performance Indicator 2.2: Describe volcano and earthquake patterns, the rock cycle, and weather and climate changes.**//
 * **2.2i: Weather describes the conditions of the atmosphere at a given location for a short period of time.**
 * **2.2j: Climate is the characteristic weather that prevails from season to season and year to year.**
 * **2.2k: The uneven heating of Earth's surface is the cause of weather.**
 * **2.2l: Air masses form when air remains nearly stationary over a large section of Earth's surface and takes on the conditions of temperature and humidity from that location. Weather locations at a location are determined primarily by temperature, humidity, and pressure of air masses over that location.**
 * **2.2m: Most local weather condition changes are caused by movement of air masses.**
 * **2.2n: The movement of air masses is determined by prevailing winds and upper air currents.**
 * **2.2o: Fronts are boundaries between air masses. Precipitation is likely to occur at these boundaries.**
 * **2.2p: High-pressure systems generally bring fair weather. Low-pressure systems usually bring cloudy, unstable conditions. The general movement of highs and lows is from west to east across the United States.**
 * **2.2q: Hazardous weather conditions include thunderstorms, tornadoes, hurricanes, ice storms and blizzards. Humans can prepare for and respond to these conditions is given sufficient warning.**
 * **2.2r: Substances enter the atmosphere naturally and from human activity. Some of these substances include dust from volcanic eruptions and greenhouse gases such as carbon dioxide, methane and water vapor. These substances can affect weather, climate and living things.** ||  ||
