Ozone is a gas that occurs both in the Earth's upper atmosphere and at ground level. Ozone can be good or bad for your health and the environment, depending on its location in the atmosphere. Ozone occurs in two layers of the atmosphere. The layer closest to the Earth's surface is the troposphere.
Description & Range: The chimney swift is a small bird with a slender body and very long, narrow, curved wings. They have small round heads, short necks, and short, tapered bill. They can grow to sizes of 5.9 inches in length with an 11.8 inch wingspan and can weigh up to 1.1 ounces. Chimney Swifts are dark-gray brown all over with lighter plumage on their neck.
Swift's grisette (or grizette as spelled in early editions of his work) is Irish, not French, and demonstrates that the generic use of the term in English to indicate a woman of loose morals already existed by 1730. Betty is presumed to be a prostitute with whom Swift had consorted in Dublin.
