Mining activities can acquire minerals like coal, which provide energy. however, mining activities are also harmful for the environment. the table below shows the number of major sinkholes formed in a mining location from 1990 to 1998. years number of sinkholes 1990 15 1992 18 1994 20 1996 58 1998 78 based on the table, which of these is the most likely year when mining operations were started in the location? (2 points) between 1990 and 1992 between 1992 and 1994 between 1994 and 1996 between 1996 and 1998

Option (3)

Explanation: In between the year 1994 to 1996, a sum of 38 number of sink holes have been found, which could be the resultant of the mining activities carried out in those two years in that particular area

                         In the mining area, drilling and other construction and excavations are carried out through which the water must have percolated down to the rocks like limestone, dolomite which has the ability to get dissolve when comes in contact with water. So this huge number of sink holes have occured there in that time period.

the correct answer: the index of refraction of the second medium is lower i tried this persons answer and it was wrong this person is lying

c.more precipitation,but only when emission levels.
