Answer:
4. Ultraviolet radiation breaks apart molecules made up of paired oxygen atoms. Individual oxygen atoms bond with paired oxygen molecules to form ozone
Explanation:
Ozone formation in the stratosphere -
The ozone is the stratosphere layer is former naturally by the chemical reaction , with the help of the ultraviolet radiation of the sun and the oxygen molecules .
In the very first step , The UV radiation breaks the oxygen molecule to give two very reactive oxygen atoms .
In the second step , the atoms of oxygen reacts with the oxygen molecules to produce the ozone molecule (O₃) .
And Ozone gas is produced .
Answer:
<u>Climate change as catastrophic, irreversible this article is taken from Guardian news</u>paper.
Explanation:
- As global warming is a long rise in the average temperatures of the earth climate it's a major aspect o climate change taking place all over the world. And it is measured by the rise in rising in surface temperature both on land and in oceans and measured continuously as its growth is continuous.
- According to the IPCC panel the the global rise in temperature form 2.8 degree to 4.8 degrees in 21st century and the possible costs associated to this event site migration of species from these place, along with the environmental impact of mass extinction or relocation natural ecosystems such as coral reefs, mountain chains and shrinking of arctic and antarctic poles.
- Various NGOs have come up that try to mitigate this change in the evolution of natural gases, either by climatic engineering or by adaptation of habitats. NASA, UNFCCC and G77 nations have taken this step towards the prevention of climatic change.
Answer: the answer is C
Explanation: i took the test
Explanation:
