What does the summer solstice mean in the twenty-four solar terms?

Answer: c answer analysis: this question belongs to cultural common sense. The summer solstice is the tenth of the twenty-four solar terms. To, it means extreme, that is, the sun grows to the extreme. On this day (northern hemisphere), the day is the longest and the night is the shortest, and the weather begins to get hot. On June 2 1 or 22 every year, the sun reaches 90 degrees of the yellow meridian, which is the "summer solstice" solar term. On the day of summer solstice, the sun directly reaches the northernmost part of the year, almost directly to the Tropic of Cancer (23 26' north latitude), and the daytime in the northern hemisphere is the longest, and the farther north it is, the longer it is. From summer to the future, the position of direct sunlight on the ground gradually moves southward, and the daytime in the northern hemisphere is shortened day by day. At this time, the southern hemisphere is in the middle of winter. So the answer is C.
