- True! The temperature decreases as we move from the equator towards the poles. This happens because the amount of solar energy, called insolation, decreases from the equator towards the poles.
- That's why places near the poles are colder compared to places near the equator where it's warmer.

Understanding Temperature Variation
Temperature indeed decreases from the equator towards the poles. This phenomenon is primarily due to the angle of sunlight and its intensity.
Reasons for Temperature Decrease:
- Sunlight Angle: At the equator, sunlight strikes the Earth more directly, leading to higher temperatures. As you move towards the poles, the angle becomes more oblique, spreading the sunlight over a larger area and reducing its intensity.
- Atmospheric Thickness: Sunlight must pass through more atmosphere at higher latitudes. This increased distance means more scattering and absorption of sunlight, resulting in cooler temperatures.
- Seasonal Variation: The poles experience extreme seasonal changes, with long winters and short summers. In contrast, the equatorial regions have relatively consistent temperatures year-round.
Climate Zones:
- Tropical Zone: Near the equator, characterized by warm temperatures and high humidity, supporting diverse ecosystems.
- Temperate Zones: Found between the tropics and polar regions, these areas experience moderate temperatures with distinct seasons.
- Polar Zones: The areas around the poles, characterized by cold temperatures and ice-covered landscapes.
Conclusion:
In summary, the statement that temperature decreases from the equator towards the poles is true. The variation in sunlight angle, atmospheric thickness, and seasonal changes contribute to this pattern, resulting in distinct climate zones across the globe.
