Where was it first discovered that the earth's ozone layer was being depleted? africa antarctica south america australia

Answers

Answer:

antarctica

Explanation

Since the Industrial Revolution period, humans have contributed to the destruction of the Ozone Layer. The release of carbon dioxide, nitric and nitrous oxides, and chlorofluorocarbons in the atmosphere make it impossible to renew ozone, allowing ultraviolet rays to penetrate the planet's surface with greater intensity.

In 1987, researchers first observed the existence of a large hole in the Ozone Layer in the Antarctic area. From then on, several surveys concluded that the ozone level has been decreasing in other parts of the planet.

Antarctica was the first to realize that the Ozone layer was being depleted in the 1980's

A state agency has contacted you to do a scientific assessment of kudzu in a nature preserve in southern Georgia. They are concerned about the effects of the non-native invasive vine on a small rare plant that grows on the forest floor in the preserve, but which is found nowhere else in the state. Kudzu is only growing in the east side of the preserve because it hasn't yet had time to invade further. In order to assess the effects of kudzu on the rare plant, you set up the following experiment: Site 1. On the east side of the park with the kudzu, you set up ten 1m x 1m plots on the forest floor. In each plot, you count the number of individuals of the rare plant.
Site 2. On the west side of the park without the kudzu, you set up ten 1m x 1m plots of the forest floor. In each plot you count the number of individuals of the rare plant.
In this experiment, Site 2 is your:

a) variable.
b) control.
c) replication.
d) hypothesis.

Answers

Answer:

Control

Explanation:

The west side of the park as a control for the experiment because it will show the rare plants species without the kudzu. I the experiment was only done in areas with Kudzu and the scientist found that there were 3 rare species than then how would they know it this was more or less normal? Also, how would the scientist know if was the kudzu that caused the change? The west side experiment helps to answer those questions. If 3 rare species were also found on the west then we would not see any connections between kudzu and the species.
