<span>A climate cycle in the Pacific Ocean with a global impact on weather patterns is called El Nino. The cycle begins when warm water in the western tropical Pacific Ocean and shifts eastward along the equator toward the coast of South America.
La Nina has cooler temperatures, not warmer ones. Temperature inversion is just a simple change of temperature. And global warming doesn't fit here as it is not a type of current.</span>
In order for the Earth to get larger, more mass would have to be added. Since no new mass is added in the process, It's size doesn't increase.
I think the second one since the largest bar (?) is for infants meaning that the population is mostly 4 year olds. Hopes this helps!
