The Ozone layer is the the atmospheric region called the stratosphere, and shields us from harmful ultraviolet B radiation that comes from the sun.

Which are best answers?

No - Ozone holes can be hole-shaped. - Actually the ozone holes are not actually holes, but an area where the ozone has been depleted or thinned.

Yes - Ozone holes allow ultraviolet light to reach the Earth's surface. - When ozone levels decrease, it allows UVB radiation to pass through and our surface is exposed.

No- Ozone holes don't have any ozone in them. - Ozone holes have lower levels of ozone in that area of the stratosphere.

Yes - Chlorofluorocarbons make an ozone hole larger. This is called the greenhouse effect. When we warm the earth's surface with these types of gases, they can trap energy from the sun. This makes it warmer on earth's surface. There has been a scientific link between CFC gasses and ozone depletion.

Yes - There is always just one ozone hole in the Earth's atmosphere. - The ozone hole forms over Antarctica because its winter allows the atmosphere to get cold enough for nacreous clouds to form in the ozone layer.

No - Ozone holes have more ozone than usual. - Ozone holes are areas where the ozone levels are depleted.

i thought a 14 year old should know this but

colonies   were tied to britain through trade and by the way they were governed.   trade was restricted so the colonies had to rely on britain for imported goods and supplies.   there were no banks and very little money, so colonists used barter and credit to get the things they needed.  

britain also needed money to pay for its war debts.   the king and parliament believed they had the right to tax the colonies.   they decided to require several kinds of taxes from the colonists to pay for the french and indian war.   these taxes included the stamp act, passed in 1765, which required the use of special paper bearing an embossed tax stamp for all legal documents.   other laws, such as the townsend acts, passed in 1767

this mainly outraged the colonies and created what we know as today as the american revolutionary war

a punishment or the threat of punishment used to enforce conformity. enforcement of norms or shared rules of conduct that tell people how to act in specific situations. social control. not everyone internalizes all of society's norms, and some people must be motivated by self-fulfillment.
