Study Guide Overview

This study guide covers the water cycle (hydrologic cycle), including key processes like evapotranspiration (evaporation and transpiration), precipitation, runoff, percolation, and plant uptake. It emphasizes the importance of the water cycle in nutrient transport and explores human impacts such as deforestation, climate change, urbanization, and water diversion. Finally, it provides practice questions and exam tips focusing on key terms, human impacts, and connections to other biogeochemical cycles.

πŸ’§ The Water Cycle: Your Ultimate Guide 🌧️

Hey there, future AP Environmental Science superstar! Let's dive into the water cycle, or as the science folks call it, the hydrologic cycle. This is the most basic of all the biogeochemical cycles, and it's super important to understand because water is the ultimate delivery service for other chemicals and matter. Think of it as the Earth's circulatory system! 🌎

Key Concept

The water cycle isn't just about water; it's a key player in moving nutrients and other substances around the planet. It's all connected! πŸ’‘

πŸ’¨ Evapotranspiration

Quick Fact

Evapotranspiration is the fancy term for all the water leaving Earth and entering the atmosphere as water vapor. It's a combo of evaporation and transpiration. πŸ’¨

  • Evaporation: The sun's heat turns liquid water into water vapor, which then rises into the atmosphere. Think of a puddle disappearing on a hot day! β˜€οΈ
