Climate classification uses long-term temperature and precipitation patterns. A climate map of the United States shows how latitude, oceans, elevation, and mountain barriers shape major regions. It guides map reading, not short-term weather forecasting.
What is wastewater treatment? Learn how sanitary wastewater moves through collection and treatment, while stormwater pollution prevention keeps runoff pollutants out of drains, soil, and waterways.
Use a world climate zone map to compare temperature and precipitation worldwide. Identify the climate zones of the world, then see how U.S. regions reflect latitude, oceans, elevation, and mountains.
Use a United States climate map to identify major North American climate regions, read temperature and precipitation patterns, and understand why boundaries vary across maps.
Climates of the world become easier to read with the Köppen system: learn what the A–E groups mean, how temperature and precipitation shape them, and how letter codes reveal seasonal patterns on maps.
Explore environmental sustainability examples and learn how environmental, social, and economic choices shape food, transport, shopping, water use, and community life.
Explore the advantages and disadvantages of hydropower: how moving water drives turbines and generators, connects to the grid, and affects emissions, ecosystems, communities, reliability, and cost.
Learn how climate zones are mapped by long-term temperature and precipitation, where major climate groups occur, and how a climate zone shapes and is reshaped by human life.
