4. What are the factors that result in different climates in different parts of the world?

The factors are

-latitude

-atmospheric circulation patterns

-oceanic circulation patterns

-geography of an area

-solar activity

-volcanic activity.

The top most important factor would be the distance from the equator.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
