I take up most of the Earth, there's five of us, so give some berth.

I fall from the sky, but I never get hurt, I quench the deep thirst of the trees and the dirt. I tap on your window, I dance on your roof, Yet I vanish away when the sun brings the proof.

I have roots below and leaves up high, I drink from the earth and reach for the sky.

A gift of the sea for castaways, made from planks and such. If dried out it's usefulness can really come in clutch.

Born on high, I drop down low, With a scaly hat on top I show. Small now, but in time I will, Become a giant on the hill.
