The beginning of the construction of dams in Holland falls on the X-XI centuries. As the earth’s crust subsided, these dams were completed. Determine how much the dam would need to be raised over the period from 1100 to 2000 if the Dutch coast fell by an average of 0.6 cm / year.

1) 2000 – 1100 = 900 years – the duration of the descending period.
2) 900 years × 0.6 cm / year = 900 years × 6 mm / year = 5400 mm = 540 cm = 5 m 40 cm
Answer: Over 900 years, the height of the dams should increase by 5 m 40 cm.
