D
The Equator
Verified step by step guidance1
Understand that solar radiation is the energy emitted by the sun that reaches the Earth. The amount of solar radiation received by a particular area on Earth depends on the angle at which the sun's rays strike the surface.
Recognize that the Earth is tilted on its axis, which affects how sunlight is distributed across the planet throughout the year. This tilt causes the sun's rays to strike different parts of the Earth at varying angles.
The Equator is the imaginary line that divides the Earth into the Northern and Southern Hemispheres. It is located at 0 degrees latitude and is equidistant from the North and South Poles.
At the Equator, the sun's rays strike the Earth most directly throughout the year. This means that the Equator receives the most consistent and intense solar radiation annually compared to other parts of the Earth.
In contrast, the North and South Poles receive less solar radiation because the sun's rays strike these areas at a much lower angle, spreading the energy over a larger surface area and resulting in less intense solar radiation.
