How Water and Carbon Cycle Through Earth

CrashCourse

In this engaging episode of Crash Course Ecology, Hank Green explores the fundamental recycling systems of our planet: the Hydrologic (Water) Cycle and the Carbon Cycle. The video explains that Earth is essentially a closed system regarding matter, meaning every atom currently on Earth has been here since the planet's formation, constantly being repurposed through biogeochemical cycles. The narration breaks down complex processes into understandable components, moving from the movement of water through states of matter to the movement of carbon through living and non-living reservoirs.
