How is a sandy shore hot on a sunny day?

A sandy shore becomes hot on a sunny day primarily due to its ability to absorb and retain heat from sunlight. The sand's low thermal conductivity means it heats up quickly when exposed to direct sunlight, while its light color reflects some solar radiation. Additionally, the lack of moisture in the sand amplifies its temperature, making it feel particularly hot underfoot. As a result, the combination of direct sunlight, sand properties, and environmental conditions leads to a hot sandy shore.

在阳光明媚的日子里，沙滩上的沙子会吸收太阳的热量，导致温度升高，因此摸起来会感觉很热。
