Seeking the answer to the question of the twilight line in high school geography
The twilight line was formed by the sun's rays passing through a point on the earth's surface. This line was called the twilight line. The closer the twilight line is to the equator, the smaller the angle of the sun's rays. Because the closer it is to the equator, the smaller the angle of the sun's altitude. The sun travels on the equator for about 12 hours, so the difference in longitude on the twilight line is also the smallest. On the contrary, the further away from the equator, the greater the sun's altitude angle, the longer the sun's rays travel on the equator, so the difference in longitude on the twilight line is greater. In high school geography, the twilight line was often used to describe the change in the length of day and night and the change in the position of the sun. When the sun is on the equator, the sun's rays are vertical to the ground. The length of day and night is equal to the twilight line. When the sun rises or sets, the rays of the sun gradually tilt so that the twilight line gradually bends. In the northern hemisphere, when the sun is due north, the twilight line points due north. The closer it is to the equator, the straighter it is. In the southern hemisphere, when the sun is due south, the twilight line points due south. The closer it is to the equator, the straighter it is. In addition, the twilight line was also used to describe the time zones and seasonal changes in different regions. By comparing the position and shape of the twilight line, one could determine the time zone and seasonal changes in different regions. For example, the area near the equator could be classified as a tropical time zone because the length of day and night was equal to the length of the twilight line. The areas near the polar circle could be divided into polar day or polar night time zones due to the small bending of the twilight line at the sun's elevation angle.

A mystery question, seeking the correct answer
Title: A person heard a strange sound at night, but there was no other sound around him. Where did the sound come from? Correct answer: The sound came from the wall or the roof. Analysis: The key to this puzzle was that the sounds people heard at night were often noisy and it was difficult to determine the source of the sound. However, if the source of the sound was limited to the night without any other interference, then the sound was likely to come from the wall or the roof. Because walls and roofs usually don't make any sound at night, other objects such as furniture and windows will also make sound at night. Therefore, the sound was most likely coming from the wall or the roof.
