Places far from the equator receive less heat because the angle at which the sun's rays hit the Earth's surface becomes more oblique as you move away from the equator. This means that the same amount of solar energy is spread out over a larger area, resulting in less heat being received per unit of surface area. Additionally, the atmosphere at higher latitudes is thicker, which can also absorb and scatter some of the incoming solar radiation, further reducing the amount of heat that reaches the surface.

The amount of heat received by places far from the equator becomes less due to the following reasons:
1. Reduced Solar Irradiance:
- The Earth's surface is curved, and places farther from the equator are tilted away from the sun.
- As a result, sunlight strikes these areas at a lower angle, with less direct irradiance (energy per unit area).
2. Attenuation by the Atmosphere:
- Sunlight travels through the Earth's atmosphere before reaching the surface.
- The atmosphere scatters and absorbs sunlight, especially in the ultraviolet and infrared wavelengths.
- This scattering and absorption reduce the amount of heat reaching the surface.
3. Higher Latitude:
- Places at higher latitudes have shorter days and longer nights.
- During the winter months, these areas receive even less sunlight due to the Earth's tilt on its axis.
4. Cloud Cover:
- Cloud cover can block sunlight from reaching the surface.
- Areas at higher latitudes tend to have more cloud cover, which further reduces the amount of heat received.
5. Surface Conditions:
- Different surface conditions can affect heat absorption.
- For example, dark surfaces (e.g., forests) absorb more heat than light-colored surfaces (e.g., snow or ice).
- Places with less vegetation or ice-covered surfaces receive less heat.
6. Ocean Currents:
- Ocean currents can transport heat from equatorial regions to higher latitudes.
- However, at higher latitudes, these ocean currents tend to lose heat to the atmosphere, reducing the amount of heat available to the surface.
As a result of these factors, places far from the equator receive less solar irradiance, experience greater atmospheric attenuation, have shorter days, and are more likely to have cloud cover and other surface conditions that reduce heat absorption. These combined effects lead to a decrease in the amount of heat received by these regions.
