The ____ contains the highest concentration of ozone.a. troposphere
c. stratosphere
b. mesosphere
d. exosphere

Answers

C. The stratosphere. About 90% of the ozone is in the stratosphere which begins about 8 miles above the Earth's surface.

Answer: Option (c) is the correct answer.

Explanation:

A layer above the troposphere and below the mesosphere is known as stratosphere.

This layer of stratosphere contains about 90% concentration of ozone and there is no occurrence of weather in this layer.

The occurrence of ozone in stratosphere makes it warmer.

Therefore, we can conclude that the stratosphere contains the highest concentration of ozone.

Which compound is a saturated hydrocarbon?

Answers

Saturated hydrocarbons are organic compounds that contain only single bonds between the carbon atoms. They are known to be the simplest organic compounds. They are termed as such because they are saturated with water. Examples are the alkanes (ethane, methane, propane, butane, etc.).
