prize1-3, Exercise 1: Heating from below

Model answer:

Most sunlight passes through the air and is absorbed by the land and sea, which warm up and then warm the air above them, so the air is heated from below.
Radiation: sunlight reaching the ground. Conduction: a warm pavement heating the thin layer of air touching it. Convection: warm air rising from a sunny field. Latent heat: heat released when water vapour condenses in a cloud.
