What characterizes the seasonal changes in daylight hours in polar regions and tropical regions?

Final answer: Polar regions undergo extreme seasonal changes in daylight, with long days in summer and long nights in winter, while tropical regions have consistent daylight due to Earth's axial tilt. Correct option a.

Seasonal Changes in Daylight Hours

The seasonal changes in daylight hours in polar regions and tropical regions are characterized by the following:

Polar Regions:

Polar regions experience drastic changes in daylight hours, with phenomena such as the midnight sun and the polar night. During the summer months, the sun may stay above the horizon for 24 hours a day, resulting in long days. In contrast, during the winter months, polar regions may experience extended periods of darkness, leading to long nights.

Tropical Regions:

Tropical regions witness relatively consistent daylight hours throughout the year. This consistency is due to Earth's axial tilt, which results in approximately 12 hours of daylight and 12 hours of darkness each day in tropical regions.

The variation in sunlight in these regions is primarily influenced by Earth's tilt of axis and its orbit around the Sun. These factors contribute to significant seasonal differences in sunlight as you move away from the equator, leading to distinct daylight patterns in polar and tropical regions.
