Explanation / Answer

1.

1. Option a is correct

Drumlins are formed of till. They are elongated features that can reach a kilometer or more in length, 500m or so in width and over 50m in height. One end is quite step, whilst the other end tapers away to ground level. The Stoss end is the steeper of the two ends and used to face into the ice flow.

The shape of some drumlins is somewhat similar to the ramp you might see being used to load large objects, like vehicles or pod storage units, on to platforms or big trucks for transportation.
