Q. Why does snow nourish the earth?
A. Because it supplies it with moisture for a considerable time; which penetrates slowly into the soil, and insinuates itself through every clod, ridge, and furrow.
Q. Why is there no snow in summer time?
A. No snow reaches the general surface of the earth in summer time, because the heat of the earth melts it in its descent.
Q. Why are some mountains always covered with snow?
A. 1st—Because the air is more rarefied; and rarefied air abstracts heat which it holds in a latent state:
2ndly—As the mountain top is not surrounded by earth to radiate heat into the air; therefore, the snow is not melted in its descent, but falls on the mountain, and lies there.
Q. Why is snow white?
A. Snow is formed of an infinite number of very minute crystals and prisms, which reflect all the colours of the rays of light; and these colours uniting before they meet the eye, cause snow to appear white.
