Environmental Science Quiz: Test Your Knowledge of Carrying Capacity & Air Quality

📚 Quick Study Guide

• 🌱 Carrying Capacity: The maximum number of individuals of a species that an environment can support indefinitely.
• ➕ Factors Affecting Carrying Capacity: Food availability, water, shelter, disease, predation, and competition.
• 📉 Overshoot: When a population exceeds its carrying capacity, often leading to a population crash.
• 💨 Air Quality Index (AQI): A measure of air quality, with higher values indicating worse air pollution.
• 🏭 Major Air Pollutants: Particulate matter (PM2.5 and PM10), ozone (O3), sulfur dioxide (SO2), nitrogen dioxide (NO2), and carbon monoxide (CO).
• 🌡️ Temperature Inversion: A condition where warm air traps cooler air near the surface, exacerbating air pollution.
• 📜 Clean Air Act: A US federal law designed to control air pollution.
• 🌍 Sustainable Practices: Reduce your carbon footprint by using public transport, conserving energy and supporting eco-friendly initiatives.
