Hi there! Let's talk about the desert and how it changes temperature.
During the day, the sun shines very brightly and makes the sand in the desert warm. The sand gets hot because it absorbs the sun's heat. That's why the desert feels so hot when the sun is up!
But when the sun goes down and the night begins, there's no more sunlight to warm the sand. So, the sand starts to cool off, and the desert becomes much cooler and sometimes even cold.
So remember: the sun warms the sand during the day, making the desert hot, and when the sun sets, without the sun's heat, the desert cools down quickly.
