Carbon Cycle
Four reservoirs (atmosphere, biosphere, oceans, fossil reserves) exchanging carbon in real time. Burn fossil fuels, plant a forest, watch the bathtub fill or drain.

Water Cycle
Sun evaporates the ocean, wind moves vapour inland, mountains squeeze out rain, rivers carry runoff back to sea. Crank the temperature: feel the conveyor belt speed up.

Greenhouse Effect
Sunlight in, IR out, greenhouse molecules trap the difference. Watch CO₂, CH₄, H₂O each grab a chunk of outgoing heat. Doubled CO₂ → +3 °C. Math meets vision.

Nitrogen Cycle
N₂ is locked behind a triple bond. Lightning, root-nodule bacteria, and Haber-Bosch are the only three keys. Humans have doubled the cycle — dead zones, N₂O, biodiversity loss.
