Which statement below about atmospheric layers is correct? the mesosphere contains a protective layer of ozone that absorbs ultraviolet radiation from the sun. the mesosphere is the atmospheric layer where weather primarily occurs. the mesosphere has a temperature that decreases to about -90c at its highest altitude of about 80 km. the troposphere contains a protective layer of ozone that absorbs ultraviolet radiation from the sun the stratosphere is located from ground level to about 10 km and has a decreasing temperature with altitude. incorrect.

Option (3)

Explanation:

The Mesosphere is the layer between the layer of the Stratosphere and the Thermosphere. It extends vertically from the height of 50 to 90 km approximately above the earth's surface. The temperature in this layer decreases with height, as there are a few molecules of air present here. As a result of which they are not able to trap the incoming solar radiation to heat the layer. The temperature drops to almost -90°C (-130°F) at the apex portion of this layer.

Thus, the temperature is extremely cold at the top of this layer.

Hence, the correct answer is option (3).
