为什么夏天会热

Summer is hot because of the way the Earth tilts toward the sun. During summer, our part of the Earth is closer to the sun.

This means we get more direct sunlight, which makes the days warmer.

Another reason is that the days are longer in summer. The sun is in the sky for more hours, so it has more time to heat up the Earth. Longer days mean more sunlight and warmth.

Lastly, the atmosphere can hold more moisture in the summer. This can make the air feel sticky and even hotter.

So, the tilt of the Earth, longer days, and more moisture in the air all work together to make summer hot.
