Why do some regions have dry seasons?
Show answer & explanation
Answer: The rain belt drifting north and south with the sun
Getting less sunlight during part of the year — Wrong. Less winter sunlight explains the cold season in temperate zones, but tropical wet and dry seasons come from the rain belt shifting, not from weaker sunshine.
Being far inland from the ocean — Wrong. Distance from the ocean affects how much moisture a region gets, but it does not create a regular wet season followed by a dry one.
The rain belt drifting north and south with the sun ✓ — Correct! In the tropics, the rain belt follows the sun north and south through the year. When it sits overhead, heavy rain falls; when it moves away, sinking air keeps the sky clear and the dry season sets in.
