Which explains the difference in the distribution of solar energy on earth surface?
The distribution of solar energy on Earth's surface varies based on several factors, including latitude, time of day, time of year, and local climate conditions. To understand the difference in the distribution of solar energy, we can consider the following points:
1. Latitude: Solar energy is distributed differently between the equator and the poles. Near the equator, the solar energy received is more intense because the sun's rays hit the Earth more directly. As we move towards the poles, the angle at which the sunlight hits the Earth's surface becomes more oblique, leading to a spread-out distribution of solar energy.
2. Time of Day: The distribution of solar energy changes throughout the day due to the sun's position in the sky. At noon when the sun is directly overhead, the solar energy is concentrated over a smaller area, resulting in higher intensity. In the early morning and late afternoon, when the sun's angle is lower, the same amount of solar energy is spread over a larger surface area, leading to lower intensity.
3. Time of Year: Solar energy distribution also varies with the time of year due to the tilt of the Earth's axis. During summer in the hemisphere tilted towards the sun, the solar energy is spread over a smaller area, resulting in higher intensity. In winter, the same amount of solar energy is spread over a larger surface area, leading to lower intensity.
4. Local Climate Conditions: Climate factors such as clouds, pollution, and water vapor content also affect the distribution of solar energy. Cloudy areas receive less solar energy as clouds reflect and scatter sunlight, reducing the intensity reaching the Earth's surface. Regions with clearer skies receive more direct and concentrated solar energy.
To understand the specific distribution of solar energy in a particular location, you can access solar radiation databases, seasonal solar charts, or use solar maps that provide information on solar energy potential for different regions. Additionally, meteorological data and satellite observations can help gather information on cloud cover and atmospheric conditions, which can further influence solar energy distribution.
