A. Summer
During summer in the northern hemisphere, the region is tilted towards the Sun, receiving more direct sunlight. This tilt of the Earth's axis is what causes the change in seasons. As a result, the northern hemisphere experiences longer days, warmer temperatures, and vegetation in full bloom. Summer solstice, which occurs around June 21st, marks the beginning of summer and is the longest day of the year in terms of daylight hours.
