1. Analyze the structural layers of Earth's atmosphere and evaluate their chemical composition, temperature gradients, and physical phenomena.
Learning Targets:
1. Identify and differentiate the five primary atmospheric layers based on altitude boundaries, temperature profiles, and air pressure variations.
2. Quantify the molecular concentrations of dominant and trace atmospheric gases, including nitrogen, oxygen, argon, carbon dioxide, and ozone.
3. Explain the thermodynamic mechanisms that drive temperature inversions in the stratosphere and thermosphere.
4. Correlate specific meteorological and atmospheric phenomena, such as aurorae, meteoric ablation, and weather formation, with their respective atmospheric layers.

2. Analyze the interactions between air masses, frontal boundaries, and atmospheric pressure systems to predict meteorological patterns and weather changes.
Learning Targets:
1. Classify air masses based on their source regions, temperature characteristics, and moisture content.
2. Differentiate the structural, thermal, and precipitative characteristics of cold, warm, stationary, and occluded fronts.
3. Evaluate the dynamics of high-pressure anticyclones and low-pressure cyclones, including wind circulation patterns and vertical air motion.
4. Interpret synoptic weather charts to forecast short-term atmospheric conditions and severe weather risks.
