TRIVIA BITS ... THE ATMOSPHERE

TRIVIA BITS ...

THE ATMOSPHERE

Without the atmosphere, it would be impossible to live on earth.

The atmosphere's layers form a "blanket" around the earth, protecting us from dangerous rays of the sun and from the cold of outer space.

The atmosphere contains the air that we breathe, water vapour, and dust.

Air contains carbon dioxide and nitrogen, vital for life, and water vapour forms the clouds that bring rain.

The atmosphere is held in place by the pull of the earth's gravity and extends to about 1,250 miles above the earth.
