Answer:
The ground is shaken 10 times less by a magnitude-4 quake than by a magnitude-5 quake.
Explanation:
The Richter scale is a system developed by American scientist Charles F. Ritcher to measure the magnitude of earthquakes according to the extent of waves detected by seismographs. In that respect, the larger the earthquake in the scale of Richter, the more damage it causes. Thus, a magnitude-5 earthquake makes the ground shake more and produces more considerable destruction than a magnitude-4 quake.

Answer:
Sinkholes are just one of many forms of ground collapse, or subsidence. Land subsidence is a gradual settling or sudden sinking of the Earth’s surface owing to subsurface movement of earth materials. The principal causes of land subsidence are aquifer-system compaction, drainage of organic soils, underground mining, hydrocompaction, natural compaction, sinkholes, and thawing permafrost. Land subsidence can affect areas that are thousands of square miles in size.

Human health can be affected by changes in air quality mainly because if the air is bad they will have various health defects. For example with some of the cities in China much of the air there is polluted. Thus human health may be affected by added stress as well as breathing in polluted air which will cause side effects.
All in all human health is affected by changes in air quality because air is what humanity breaths to survive. If in some way this air were to be polluted we would suffer from decreased health due to a circulation of fossil fuels in our atmosphere.
