3 December: Weve hit 9 hours of daylight at our latitude peeps. But, well only lose about 13-14 more minutes of daylight, then its time to increase. Fact of the Day: atmosphere Without the atmosphere, it would be impossible to live on earth. The atmospheres 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 vapor, and dust. Air contains carbon dioxide and nitrogen, vital for life, and water vapor forms the clouds that bring rain. The atmosphere is held in place by the pull of the earths gravity and extends to about 1,250 miles above the earth.
