In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
The Earth's atmosphere is the origin of the weather phenomena studied in meteorology. Atmospheric composition, temperature, and pressure vary across a series of distinct sublayers including the troposphere and stratosphere. The properties of Earth's atmosphere vary by altitude across a series of distinct layers. atmospheric boundary layer (ABL)
