Why do some regions have dry seasons?
Show answer & explanation
Answer: The rain belt drifting north and south with the sun
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.
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.
