Insolation is primarily caused by the direct exposure of an object or surface to the sun's radiation. It is influenced by factors such as the angle of incidence, duration of exposure, and atmospheric conditions like cloud cover and air pollution. Insolation levels can vary based on geographic location, time of year, and time of day.
The poles have the lowest insolation due to the tilt of Earth's axis, resulting in less direct sunlight reaching those regions. This causes colder temperatures and less energy available for heating.
The season with the highest angle of insolation is summer. This is due to the Earth's tilt on its axis, which causes the Sun's rays to be more direct during summer months in each hemisphere.
The polar regions, particularly the poles, receive the lowest insolation due to their high latitude and the tilt of Earth's axis. These areas experience prolonged periods of darkness during winter, leading to limited sunlight and low insolation levels.

Angle of insolation refers to the angle at which the sun's rays strike the Earth's surface. The angle of insolation affects the intensity of solar energy received at a particular location. A higher angle of insolation results in more concentrated sunlight, while a lower angle spreads the sunlight out over a larger area.
