What describes daily conditions like rain, temperature, and wind?
Weather
400
What type of front forms when a cold front overtakes a warm front?
Occluded front

Why do maritime air masses contain more moisture than continental air masses?
They form over oceans where it is more humid cause water evaporates into the air.
