What is groundwater, and where is it stored?1 / 8

Groundwater is water that has soaked into the ground and now fills the spaces between soil particles and cracks in rock beneath the surface. It's not stored in vast open caverns everywhere — mostly it fills the tiny pore spaces of permeable soil and rock, like water in a sponge.

What is a life-cycle assessment (LCA)?1 / 9

A systematic method for evaluating the total environmental impact of a product or material across its entire life — from raw material extraction through manufacturing, use, and disposal — rather than looking at just one stage in isolation.

Radioactive decay and half-life Radioactive isotopes decay at a constant fractional rate. If N₀ atoms are present at time zero, the number remaining at time t is N = N₀ · e^(−k·t), where k is the decay constant. The half-life t½ = ln(2)/k i

Why do wetland soils decompose organic matter so much more slowly than dry upland soils?1 / 9

Wetland soils are waterlogged, which blocks oxygen from diffusing in. Most efficient decomposition needs oxygen (aerobic respiration), so in these anaerobic conditions dead plant material breaks down far more slowly than it accumulates.
