Basket-of-eggs topography is related to
- A.Drumlins.
- B.Eskers.
- C.Cirques.
- D.Moraines.
Correct answer
Explanation
The correct answer is A, Drumlins. A field of many drumlins lying side by side looks like eggs packed in a basket, so it is called basket-of-eggs topography.
Drumlins are smooth, oval hills of glacial till, the mixed clay, sand and boulders left by a moving ice sheet. Each is shaped like an inverted spoon or half an egg, with a blunt, steeper end facing the direction from which the ice came and a gentle tapering end pointing the way it moved. They often occur in swarms, as in parts of Ireland, northern England and Canada, and help geologists work out the flow of old ice sheets.
B is wrong because eskers are long, winding ridges of sand and gravel laid down by streams flowing under a glacier. C is wrong because cirques are armchair-shaped hollows cut by ice at the head of a mountain valley, an erosional form. D is wrong because moraines are ridges or sheets of debris along the sides, end or floor of a glacier.
Exam tip: drumlins, basket of eggs; eskers, winding ridges; cirques, armchair hollows.
