Final Answer:
The opposite of a polar climate is Temperate climate.
Thus option b is correct.
Explanation:
The opposite of a polar climate is a temperate climate, characterized by moderate temperatures and distinct seasons. Polar climates are found near the Earth's poles, experiencing extremely cold temperatures year-round, while temperate climates are located between the tropics and polar regions, exhibiting more moderate and varied temperatures.
Polar climates are defined by their low average temperatures, often below freezing, due to the tilt of the Earth's axis away from the sun in these regions. In contrast, temperate climates enjoy a wider range of temperatures throughout the year, with warmer summers and cooler winters resulting from a more balanced exposure to sunlight across the seasons.
The distinction between these climates lies in their geographical positions and the angle at which sunlight reaches the Earth's surface. Polar regions receive oblique sunlight, spreading its energy over a larger area and resulting in colder temperatures. In contrast, temperate regions receive more direct sunlight, allowing for a greater amount of solar energy per unit area, resulting in milder temperatures.
Therefore, while polar climates are characterized by perpetual coldness and limited variation in daylight, temperate climates showcase a more diverse range of temperatures and distinct seasonal changes, making them the opposite climate type to the polar regions.
Therefore option b is correct.
