why are the temperate zone called so? why do mainly grasses grows in these regions​

Answer 1

Answer:

the mid-day sun is exactly overhead at least once a year on all latitudes in between the tropic of cancer and the tropic of Capricorn. this area ,therefore,receives the maximum heat and is called the torrid zone.

the mid sun is never shines overhead on any latitude beyond the tropic of cancer and the tropic of Capricorn.the angle of sun'rays goes on decreasing towards the poles.as such,this area bounded by the tropic of cancer and the attic circle in the northern hemisphere .and the tropic of Capricorn and the Antarctic circle in the southern hemisphere,have moderate temparates. these are, therefore,called temperate zones
