The seasons change because of Earth’s tilted axis, which does not change direction as Earth orbits the Sun.
In June, the northern hemisphere is tilted towards the Sun so has summer, and the southern hemisphere has winter.
In December, the northern hemisphere is tilted away from the Sun so has winter, and the southern hemisphere has summer.
The seasons that occur at a place on Earth can be explained by the different angles made to the sun's rays over a year.
Countries near the Equator do not experience summers and winters as they stay close to ‘face-on’ to the Sun all year.
