INDIAN GEOGRAPHY

Detailed explanation-1: -Because the earth is round, or spherical, and tilted, solar energy is not evenly distributed over the entire planet. Some parts of the earth receive more or less solar radiation than others. This is because the angle of the sun rays on Earth are more direct in some areas and less direct in others.

Detailed explanation-2: -The Earth revolves around the sun in an elliptical orbit and is closer to the sun during part of the year. When the sun is nearer the Earth, the Earth’s surface receives a little more solar energy. The Earth is nearer the sun when it is summer in the southern hemisphere and winter in the northern hemisphere.

Detailed explanation-3: -The insolation (incoming solar energy) received on a daily basis depends primarily on 1) the angle of the Sun above the horizon (solar elevation angle, solar incidence angle), 2) the length of time the surface is exposed to the Sun, and 3) atmospheric conditions.

Detailed explanation-4: -The equator gets the most direct sunlight year-round. The angle of sunlight hitting the equator is more direct than it is at the poles, so the poles receive less direct sunlight.

Detailed explanation-5: -The Sun doesn’t heat the Earth evenly. Because the Earth is a sphere, the Sun heats equatorial regions more than polar regions. The atmosphere and ocean work non-stop to even out solar heating imbalances through evaporation of surface water, convection, rainfall, winds, and ocean circulation.
