Why does land heat up to higher temperature than an adjacent area of water?

Water is a slow conductor of heat, thus it needs to gain more energy than the sand or dry land in order for its temperature to increase. On the other hand, soil loses its heat much faster Water has to lose more energy than the sand (dry land) in order for the temperature to decrease.

The answer is c) people evacuated but almost all returned

Increasing the release of greenhouse gases and pollution
