'Paternoster Lake' is a ..................... feature.

  • A.Riverine
  • B.Aeolian
  • C.Karstic
  • D.Glacial

Answer: D

Paternoster lakes are a glacial feature.

A glacier eroding its valley deepens it unevenly, scouring out a series of rock basins where the rock is weaker or the ice was more erosive, separated by rock steps. When the ice melts these basins fill with water, giving a chain of small lakes down the U-shaped valley, likened to the beads of a rosary (the paternoster).

Riverine lakes include ox-bow and scroll lakes, aeolian processes make deflation hollows, and karstic lakes form in limestone solution features such as poljes and dolines. None gives a chain of rock basins along a valley.
