Answer 1

Grazers & browsers have long flexible upper lips they use to sort out unwanted vegetation.
The elephant's fossil record shows an ancestral relationship with pig sized creatures that had very long jaws and a tapir like snout to facilitate maneuvering plant matter into their unwieldy jaws. The long jaws could reach more food and masticate tough leaves effectively but they were heavy and awkward to support in larger animals. "Over the generations the head and jaws became shorter and the snout, combined with the upper lip, became a long, flexible proboscis." Smaller lighter jaws with ever longer snouts enabled ever taller herbivores able to reach vegetation either in high branches or on the ground.
Giraffes have long necks and legs while elephants have long legs and trunks but all graze trees. However elephants use their mass & tusks from their long jawed days to dismember trees in order to reach more leaves.

Answer 2

Because they only have relatively short legs and if they get a cold they wouldn't be able to reach the end of their nose to blow it,so their trunks have evolved so that they can reach their nostrils with a tissue.

Answer 3

its because of the food they eat...elephants are herbivores so their trunks developed to help them to get vegetations up on trees

Answer 4

its not a nose its its trunkthe nose on the end of the trunk. witch is used to snap branches off trees to eat etc and to snort up water.

Answer 5

well, they use it as an arm to reach things and to pick up their food,
