Coastal california is famous for fog and smog (fog mixed with smoke). why is the california coast foggy/smoggy, whereas houston, texas, which is at similar latitude, might get occasional smog from too many cars, but fog is relatively rare?
a) warm air in texas rises to make clouds and not fog, whereas in california cold water from the ocean mixes with warm water from the land to generate fog.
b) the ocean is warm off the texas coast, but a cold current running offshore california generates fog when the cold, moist air is drawn ashore by a sea breeze.
c) cold currents along the texas coast inhibit fog, whereas the ocean is warm off california.
d) there isn't really any fog; it is all just smog from too many
