The stratosphere defines a layer in which temperatures rises with increasing altitude. At the top of the stratosphere the thin air may attain temperatures close to 0° C. This rise in temperature is caused by the absorption of ultraviolet (UV) radiation from the Sun by the ozone layer. Such a temperature profile creates very stable atmospheric conditions. Consequently, the stratosphere is almost completely free of clouds or other forms of weather.

Correct Option: C

The ozone layer of Earth’s stratosphere absorbs most of the Sun’s ultraviolet radiation. It absorbs 97 to 99 percent of the Sun’s medium-frequency ultraviolet light (from about 200 nm to 315 nm wavelength), which otherwise would potentially damage exposed life forms on the earth.

Correct Option: B

The ozone layer of Earth’s stratosphere absorbs most of the Sun’s ultraviolet radiation. It absorbs 97 to 99 percent of the Sun’s medium-frequency ultraviolet light (from about 200 nm to 315 nm wavelength), which otherwise would potentially damage exposed life forms on the earth.

The equatorial regions are known for convectional rainfall that occurs due to the thermal convection currents caused due to the heating of ground due to insolation. In these, the warm air rises up and expands then, reaches at a cooler layer and saturates, then condenses mainly in the form of cumulus or cumulonimbus clouds. The equatorial regions receive convectional rainfall almost on a daily basis. The rainfall is of very short duration but in the form of heavy showers.

The ozone layer is a region of Earth’s stratosphere. it is mainly found in the lower portion of the stratosphere, from approximately 20 to 30 kilometres (12 to 19 mi) above Earth. The ozone layer absorbs 97 to 99 percent of the Sun’s medium-frequency ultraviolet light (200 nm to 315 nm wavelength), which otherwise would be harmful to exposed life forms on the earth.

Western Disturbance is an extratropical storm originating in the Mediterranean region that brings sudden winter rain to the northwestern parts of the Indian subcontinent.Jet streams play an important role in bringing these disturbances to India. Western disturbances are generally active from December to February.
