Question

which part of earth most likely has the highest albedo value?
○ smooth ocean ice when the sun is at a 30 - degree angle
○ smooth ocean ice when the sun is at a 15 - degree angle
○ choppy ocean water when the sun is at a 30 - degree angle
○ choppy ocean water when the sun is at a 15 - degree angle

Explanation:

Albedo is the measure of the reflectivity of a surface. Ice, especially smooth ice, reflects more sunlight compared to water (which absorbs more). Among the options, smooth ocean ice (as it's ice, a high - reflective surface) is considered. Also, when the Sun is at a lower angle (15 - degree in this case for the ice option), the reflection (related to albedo calculation considering the angle of incidence) plays a role. But mainly, the type of surface (ice vs water) is the primary factor. Ice has a higher albedo than water.

Answer:

smooth ocean ice when the Sun is at a 15 - degree angle
