What is the usual shape of an esker?
Answer and explanation
Correct answer: A long, winding ridge of gravel and sand
An esker is a long, narrow, winding ridge made mainly of sand and gravel deposited by streams that once flowed beneath or within a glacier. When the ice melts, the sediment-filled channel remains as a raised ridge on the landscape. Option A is correct because its sinuous ridge form is characteristic. A sea cliff, marine island, or river pothole has a different agent and origin.
