Archaeologists unearthed an ancient site at an altitude of 212 m and found a fisherman’s boat moored at this location. Geological scientists have established that the lithospheric plate in this place rises at a speed of 0.6 cm / year. Determine when there was a body of water at the site of the hill.
The rate of rise of the lithospheric plate: 0.6 cm / year = 0.06 m / year = 6 m / century
6 m -100 years
212 m – X years
X = 212 × 100: 6 = 3533 years – it took the slab to rise 212 m.
Answer: 3533 years ago there was a sea on the site of the hill.
