Question

Ozone umbrella is located in which layer of atmosphere

Answer 1

stratosphere

ozone layer is present in lower portion of stratosphere.

Answer 2

Answer:

The ozone umbrella is located in the stratosphere layer of the atmosphere.

Explanation:

• Atmosphere/air is a transparent, protective, envelope of gases surrounding the Earth (Hydrosphere and lithosphere) up to 300km above the Earth's surface.

• Different layers of the atmosphere include the Troposphere, Stratosphere, Mesosphere, Ionosphere and Exosphere.

• Out of the above-mentioned layers, the second layer of the earth's atmosphere- the stratosphere essential for living organisms. It possesses the ozone shield or ozone umbrella.

• Since it filters harmful, high-energy ultraviolet(UV) rays that come from the Sun to the Earth's surface is called-ozone layer is called an ozone umbrella or shield.

• UV rays split the ozone into molecular and atomic oxygen, thereby releasing the heat and warming the stratosphere. In this way, the ozone layer protects the Earth.

           O₃(Ozone)   +  (UV)  →         O₂        +      [O]      +   Heat↑

                                                    Molecular      Atomic

                                                      oxygen         oxygen

• Ozone, an unusual type of oxygen molecule that is relatively abundant in the stratosphere, heats this layer as it absorbs energy from incoming ultraviolet radiation from the Sun.
