GED® Science: Earth's Water & the Water Cycle (Deep Dive)

A deep dive into Earth's water, expanding the single 'Earth's Water & the Water Cycle' lesson from the GED® Earth & Space Science course into a full mini-course. You'll see where Earth's water really is (and why so little is usable), follow the full water cycle from the ocean to the clouds and back into the ground, and learn the physics of how water changes state and stores energy. You'll also explore clouds and precipitation, groundwater and aquifers, and why fresh water is a limited resource worth protecting. Plain language, all-new labeled diagrams, common-misconception warnings, and GED®-style practice with full explanations throughout.
