How does a glacier form?1 / 8

A glacier forms where snowfall exceeds melting year after year. Fresh snow gets buried and compacted by the weight of new snow above it, first turning into a grainy intermediate stage called firn, then — after decades of further compression squeezing out the air — into dense glacial ice.

In one sentence, how does the greenhouse effect actually warm the Earth?1 / 9

Greenhouse gases let incoming shortwave sunlight pass through to warm the surface, but absorb and re-radiate the outgoing longwave (infrared) radiation the surface emits — trapping some of that energy instead of letting it escape straight to space.

What is a 'linear economy,' in the take-make-dispose sense?1 / 9

An economic model where raw materials are extracted, made into products, used, and then thrown away as waste — resources flow in one direction and are not recovered.
