Final answer:
Chattanooga and Buenos Aires have different daylengths due to their positions relative to the equator and the changing seasons. Limon has longer daylight hours than the equator around the equinoxes.
Step-by-step explanation:
The length of daylight in different locations is influenced by the Earth's tilt on its axis and its orbit around the Sun. Chattanooga and Buenos Aires are both located at 35 degrees latitude, but their daylengths differ because of their positions relative to the equator and the changing seasons. The amount of daylight at a specific location is determined by factors such as the angle at which the sunlight reaches the Earth's surface and the duration of daylight as the Earth rotates.
At the equator, there are approximately 12 hours of daylight and 12 hours of night throughout the year. As we move away from the equator, towards the poles, the length of daylight varies more significantly. This is because at higher latitudes, the angle at which the sunlight reaches the Earth's surface becomes more oblique, resulting in shorter days during certain times of the year.
Limon, which is located at a latitude closer to the equator than the equator itself, would have longer daylight hours than the equator during specific periods. This occurs around the equinoxes, which are around March 21st and September 21st. During these times, the Sun is directly over the equator, and every place on Earth receives roughly 12 hours of daylight and 12 hours of night.
