High school biology quiz: The greenhouse effect and climate.

📚 Quick Study Guide

• ☀️ Greenhouse Effect: The process where certain gases in the Earth's atmosphere trap heat, warming the planet. Think of it like a blanket!
• 🌡️ Greenhouse Gases: Key gases include carbon dioxide ($CO_2$), methane ($CH_4$), nitrous oxide ($N_2O$), and water vapor ($H_2O$). These gases absorb and emit infrared radiation.
• 🏭 Human Impact: Activities like burning fossil fuels, deforestation, and industrial processes increase greenhouse gas concentrations.
• 📈 Climate Change: The long-term alteration of temperature and typical weather patterns in a place. Primarily caused by increased greenhouse gas emissions.
• 🧊 Consequences: Rising global temperatures, melting ice caps and glaciers, sea-level rise, altered precipitation patterns, and more frequent extreme weather events.
• 🌱 Mitigation: Efforts to reduce greenhouse gas emissions, such as using renewable energy sources and improving energy efficiency.
• 🔄 Feedback Loops: Processes that can amplify or diminish the effects of climate change. For example, melting ice reduces Earth's reflectivity, leading to further warming.
