Some ultraviolet radiation is absorbed by clouds in the upper stratosphere. true false

This statement is True.

Ultraviolet (UV) radiation from the sun consists of different wavelengths, which are categorized into UVA, UVB, and UVC. While a significant portion of UV radiation is absorbed by the ozone layer in the stratosphere, which is crucial for protecting living organisms on Earth, some UV rays can be absorbed by clouds as well.

Clouds consist of water droplets or ice crystals that scatter and absorb various forms of radiation. In the upper stratosphere, clouds can intercept some UV radiation, further contributing to the reduction of UV exposure reaching the Earth's surface. However, it's important to note that the extent of this absorption can vary depending on the cloud type, thickness, and altitude.

In summary, clouds do play a role in absorbing some UV radiation in the upper stratosphere, supporting the truthfulness of the statement.
