Availability of light on land is closely linked with that of

Options

A. temperature
B. light
C. water
D. soil

Answer

**Step-by-Step Solution:**

1. **Understanding the Relationship Between Light and Temperature:**
- The availability of light on land is closely linked to temperature. This is because regions that receive more sunlight tend to have higher temperatures.

2. **Geographical Influence:**
- The equator receives the most direct sunlight, resulting in the highest temperatures, typically around 26 to 28 degrees Celsius. This is due to the angle at which sunlight strikes the Earth.

3. **Tropical Regions:**
- Moving away from the equator, tropical regions still receive significant sunlight, leading to temperatures ranging from 21 to 30 degrees Celsius. The intensity of light is still relatively high in these areas.

4. **Temperate Regions:**
- Further from the tropics, temperate regions experience less light intensity and, consequently, lower temperatures, generally below 18 degrees Celsius. The light has to travel a longer distance, which reduces its intensity.

5. **Polar Regions:**
- At the poles, light availability is minimal, leading to extremely low temperatures, often around -20 to -30 degrees Celsius. The lack of sunlight directly correlates with the cold climate.

6. **Conclusion:**
- Therefore, the availability of light on land is closely linked with temperature. The more light that is available, the higher the temperature tends to be.

**Final Answer:**
The availability of light on land is closely linked with temperature.
