1. Earth's Tilt: The tilt of Earth's axis is responsible for causing seasonal changes and varying angles of insolation at different locations. The angle of tilt changes the amount of insolation that reaches the surface of the earth.
2. Atmospheric Conditions: The Earth's atmosphere reflects and scatters sunlight, which means that the angle of insolation varies depending on the presence of clouds, greenhouse gases, and aerosols.
3. Geographical Location: Areas closer to the equator receive more direct angles of insolation than those near the poles due to the curvature of the Earth. Moreover, the Earth's rotation and revolution also impact the angle of insolation at the different locations throughout the year.
4. Time of Day: The angle of insolation can vary based on the time of day. Sunlight is more direct at noon than in the early morning or late afternoon when the sun is low on the horizon.
5. Reflection and Absorption: The angle of insolation can be affected by the amount of reflection and absorption that occurs. Materials such as snow, water, and foliage reflect or absorb sunlight, which results in varying angles of insolation.
