Earth's Processes Close-Up explores what lies beneath our feet - the land and water that make up our ever-changing Earth. The series explains how landforms such as mountains, caves, valleys, and coastlines are shaped by wind, water, and gravity. Designed to support the NGSS topic: Earth's Systems: Processes that Shape the Earth, the series explores gradual land changes such as those caused by weathering and erosion, as well as events such as volcano eruptions and earthquakes, which can quickly alter the landscape. Also featured are the ways to prevent these changes and the reasons behind them. Text-based questions, key vocabulary, and an investigation make content meaningful and relevant to young readers.
