Question

Quizplus · Accepted Answer

A geyser, like a coffee percolator, uses pressure and heat to force water through a confined space and up to the surface. Old Faithful and other geysers work by underground chambers filling with hot water and steam, which eventually become pressurized enough to force the water up and out of the vent at the top, much like a coffee percolator. The other options (vacuum bottle, canteen, teakettle, vat of molten lead) do not share this same mechanism of action with a geyser.
