Answer:
" Atmospheric instability is critical weather-maker "
Explanation:
- Instability is a condition where the earth's atmosphere is generally considered to be unstable as a result of the weather is subjected to a higher degree of variability over a larger distance and time.
- In metrology, instability is defined by the changes in temperature from the inversion layer in the form of a lapse rate. As the air gets unstable it has two forms as convective and dynamic instability.
- The dynamics are produced by horizontal motion and rest by the vertical motion. It is subject to Coriolis force and pressure gradient force. Thus dynamic lifting and mixing produced the cloud, precipitation, and storms.
- If the unstable atmosphere gets larger it leads to certain problems like dust veils when the winds are light and region of ground instability.

Answer:
<em>That is, the wave amplitude in a level 6 earthquake is 10 times greater than in a level 5 earthquake, and the amplitude increases 100 times between a level 7 earthquake and a level 9 earthquake. The amount of energy released increases 31.7 times between whole number values.</em>
