Question

Which of the following objects reflect more energy?

• A. Smooth and moist object surfaces
• B. Rough and moist surfaces
• C. Smooth and dry object surfaces
• D. Rough and dry surfaces

Hint:

Smooth, dry surfaces reflect more energy; moisture and roughness reduce reflectivity.

Answer 1

The Correct Option is C

The capability of an object to reflect energy is closely tied to its surface properties. In geo-engineering and geo-informatics, understanding how surfaces interact with energy is crucial. Let's analyze the options based on the influencing factors for reflectivity:

1. Smooth surfaces: These tend to reflect more energy compared to rough surfaces. A smooth surface allows light to reflect in a more orderly fashion, contributing to higher reflectivity.
2. Moist vs. dry: Moist surfaces absorb more energy due to the presence of water, which has high absorptivity. Conversely, dry surfaces tend to reflect more energy as there's less absorption.

Given these points, smooth and dry object surfaces will reflect more energy because they have minimal absorption (due to dryness) and high orderly reflection (due to smoothness).
