What's the difference between fog and haze?

Fog is basically a cloud at ground level. Fog is composed of tiny water droplets that stay suspended in the air, instead of falling to the ground like rain or drizzle.

Erica's Answer:

Fog reduces visibility, which is why it can get confused with haze. Hazy skies also have a reduced visibility, but it is a separate phenomenon from fog. Haze particles can include salt, pollutants, dirt, and sometimes water vapor. We often see haze in the summer, because hot and humid conditions make it harder for pollutants to scatter outside of urban areas.
