astronomy - What's the reason for the seasons?



Diagram of Sun and Earth


In the diagram, it shows that the fundamental reason for different seasons is when the northern hemisphere is titled towards the sun there's summer in northern hemisphere and winter in southern hemisphere and vice-versa after the six months.


But because the earth spins around its axis, why doesn't the seasons change during day and night? is there something missing in the diagram to prove that?
