Hi there! Let me explain why the desert feels hot during the day and cold at night.
During the day, the sun shines brightly and its rays warm up everything they touch. The sand in the desert is very good at getting warm, so it heats up quickly. Because the sand gets hot, the air around it also feels hot, making the whole desert warm.
But when the sun goes down and sets, it stops sending warm rays. The sand doesn’t hold the heat for very long, so it cools down quickly. Without the sun’s warmth, the desert becomes cold at night.
So, the desert is like a big warm blanket during the day because of the sun and sand, but it turns cold pretty fast when the sun is gone!
