Water Facts Booklet & Heat Capacity
Water's unique properties — especially its high heat capacity — are what make Earth's climate livable. Oceans absorb enormous amounts of heat in summer and release it slowly in winter, moderating temperatures far more than land surfaces do.
Water Facts Booklet
A student booklet covers key water properties including chemical formula, states of matter, density, and surface tension.
Heat Capacity Page
One booklet page focuses on heat capacity — why oceans warm and cool more slowly than land, and how this drives coastal climates.
Why water's heat capacity matters for climate
Water absorbs about four times more heat per degree than most land surfaces. This is why coastal cities have milder, more stable temperatures than inland cities at the same latitude — the ocean is constantly absorbing and releasing heat, smoothing out the extremes. Ocean currents driven by this heat difference are one of the primary forces that distribute warmth around the planet.
