2.ESS.1 The atmosphere is primarily made up of air.
2.ESS.1.a Air has properties that can be observed and measured. The transfer of energy in the atmosphere causes air movement, which is felt as wind. Wind speed and direction can be measured.
2.ESS.2 Water is present in the atmosphere.
2.ESS.2.a Water is present in the atmosphere as water vapor. When water vapor in the atmosphere cools, it forms clouds, fog, rain, ice, snow, sleet or hail.
2.ESS.3 Long- and short-term weather changes occur due to changes in energy.
2.ESS.3.a Changes in energy affect all aspects of weather, including temperature, precipitation, and wind.
