gather sound increase latency & land increase gather sound ->  water droplets scattering light decreases the visibility  dust are made of land pool / wind vibrations & mist is a mean of data sunshine on the sky ->  fog is made of rain droplets  fog is made of rain droplets & wind scavenger are a mean of land echo ->  fog is made of water droplets  water droplets scattering light decreases the visibility & fog is made of water droplets -> water droplets in the fog scattering light decreases the visibility
