Which statement best describes the apparent relationship between comme and UV-87

A) When ozone levels are at 2550 Dobson unita, the UV-8 levels are at 250 Dobson units.

Bi The increase in UV-B reduces the destruction of the one layer

When the aurone layer is thinner, more UV-8 gets through it.

D) If the ozone layer is thicker, UV-B levels on the ground increase

Answer 1

The major effect of acid rain in lakes is not an increase in game fish population levels, but rather the elimination of many species of aquatic life. Acid rain is detrimental to aquatic ecosystems because it increases the acidity of the water, making it difficult for many species of plants and animals to survive.

In terms of the relationship between ozone levels and UV-B levels, the statement that best describes the apparent relationship is: When the ozone layer is thinner, more UV-B gets through it. This means that when the ozone layer is depleted or damaged, more UV-B radiation reaches the Earth's surface. This is concerning because UV-B radiation can be harmful to living organisms, causing skin damage, eye problems, and even an increased risk of skin cancer.
