1. Angle of Incidence:
* Equator: The sun's rays hit the equator at a more direct angle (closer to 90 degrees). This means the energy is spread over a smaller area, resulting in higher temperatures.
* Poles: The sun's rays hit the poles at a more oblique angle (closer to 0 degrees). This means the energy is spread over a larger area, resulting in lower temperatures.
2. Earth's Tilt:
* Summer: When the hemisphere is tilted towards the sun, it receives more direct sunlight and experiences longer days, leading to warmer temperatures.
* Winter: When the hemisphere is tilted away from the sun, it receives less direct sunlight and experiences shorter days, leading to colder temperatures.
3. Distance from the Equator:
* Equator: Locations near the equator receive more consistent sunlight throughout the year, leading to more stable temperatures.
* Poles: Locations closer to the poles experience greater variations in sunlight and temperature due to the tilt of the Earth.
4. Altitude:
* Higher altitude: Air at higher altitudes is thinner and less dense, making it less effective at trapping heat. This leads to cooler temperatures in mountainous regions.
* Lower altitude: Air at lower altitudes is denser and more effective at trapping heat, leading to warmer temperatures in valleys and plains.
5. Ocean Currents:
* Warm currents: Ocean currents can transport warm water from the equator towards the poles, moderating temperatures in coastal regions.
* Cold currents: Ocean currents can transport cold water from the poles towards the equator, cooling down coastal regions.
6. Cloud Cover:
* More cloud cover: Clouds reflect sunlight, reducing the amount of solar radiation reaching the ground and leading to cooler temperatures.
* Less cloud cover: Clear skies allow more sunlight to reach the ground, leading to warmer temperatures.
In conclusion, the amount of heat you receive from the sun is a complex interplay of these factors, resulting in different temperatures across the globe.
