There is only one climate type in motion across the world at a time

The statement that states there is only one climate type in motion across the world at a time is false.

Explanation:

The world is divided into different climatic zones. For the northern hemisphere, these zones can be named in the order of their presence from the topmost latitudes to the lowermost latitudes as the polar zone, temperate zone, tropical zone (the order is reversed in the southern hemisphere). These climatic zones broadly govern the climate of the regions that fall into these zones.

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.
