Q

The reason why we have seasons on earth

A

sunlight is more direct and therefore more intense in the summer because the sun is higher in our sky, particularly at noon. The sun’s path is long and high in the summer, low and short in the winter, owing to the steady 23 1⁄2 degree tilt as the earth orbits the sun each year.
