The albedo effect refers to the ability of a surface to reflect sunlight back into space. Higher albedo means more sunlight is reflected, resulting in a cooler temperature. In this question, we are asked to determine when the albedo effect would be relatively higher.

Option 1 states that the albedo effect would be relatively higher in early morning and late evening. This is because during these times, the angle of sunlight is lower, causing the light to encounter the surface at a more oblique angle. When the angle is more oblique, the light has a greater chance of being reflected rather than absorbed. Therefore, the albedo effect would be relatively higher in early morning and late evening.

Option 2 states that the effect would only be higher in early morning. This is incorrect because the albedo effect is also influenced by the angle of sunlight, which is lower in the late evening.

Option 3 states that the effect would be highest at noon. This is incorrect because during noon, the angle of sunlight is more perpendicular to the surface, resulting in less reflection and more absorption.

Option 4 states that the effect would only be higher in late evening. This is incorrect because the albedo effect is also influenced by the angle of sunlight, which is lower in the early morning
