Winds, Storms And Cyclones Questions

We provide winds, storms and cyclones practice exercises, instructions, and a learning material that allows learners to study outside of the classroom. We focus on winds, storms and cyclones skills mastery so, below you will get all questions that are also asking in the competition exam beside that classroom.

the formation of winds due to uneven

warmer winds in the ( 60^{circ} ) belt and constitute the Polar
winds.
