How does earth's surface affect duration of insolation?

Answer 1

When Earth revolves around the sun different areas will get different amounts of insolation. For example, in the Northern Hemisphere our winter days are shorter and summers are longer.

Answer 2

Earth's surface affects the duration of insolation by influencing the angle at which sunlight strikes it due to factors like latitude and topography. Regions near the equator receive more direct sunlight and experience longer durations of insolation, leading to warmer climates, while regions closer to the poles receive less direct sunlight and have shorter durations of insolation, resulting in colder climates. Additionally, features like mountains and clouds can also impact how much sunlight reaches the surface.
