An elongated hill that is composed of unsorted sediments deposited by a glacier is called

(1) a delta

(2) a drumlin

(3) a sand dune

(4) an outwash plain

I believe the correct answer from the choices listed above is option 2. An elongated hill that is composed of unsorted sediments deposited by a glacier is called a drumlin. These occur widely within the moulded and streamlined scenery of the central lowlands of Scotland.

Hope this answers the question. Have a nice day.
