5 Must Know Facts For Your Next Test

1. Solar intensity varies with latitude, being highest at the equator and decreasing towards the poles.
2. It affects photosynthesis rates in plants, impacting primary productivity in different biomes.
3. Seasonal changes in solar intensity result from Earth's axial tilt, leading to varying climates and weather patterns.
4. Atmospheric conditions, such as cloud cover and pollution, can modify the amount of solar energy reaching Earth's surface.
5. Solar intensity plays a crucial role in driving global wind and ocean currents, which distribute heat and affect climate.
