Why Cities Are Hotter Than the Countryside

~60 min · 15 stations

Why Cities Are Hotter Than the Countryside is a self-paced learning path in Architecture & Design, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify the primary characteristics of urban heat islands; compare rural surface cooling with urban heat retention; analyze how sunlight interacts with various building materials.

Conductor

The Conductor

Welcome aboard the urban climate express. We are diving into why our concrete jungles hold onto the sun's heat so tightly. Mind the gap between the rural grass and the city asphalt.
