which of the following does the best job of blocking out sunlight? check all that apply.
sulfur
soot
fine dust
clouds

Explanation:

Soot is a black powdery substance that can effectively block sunlight due to its dark color and fine particulate nature. Clouds can also block sunlight as they consist of water droplets or ice crystals that scatter and absorb sunlight. Sulfur in its elemental form is not typically a major blocker of sunlight in the context of common substances that block sunlight in the atmosphere. Fine dust can scatter sunlight but is generally less effective at blocking it compared to soot and clouds in terms of the degree of blocking.

Answer:

soot, clouds
