What is the definition for moraine in earth science?

A moraine is a landform made up of rocks, sediment, and debris that have been deposited by a glacier as it moves or melts. Moraines can be found at the edges, front, and underneath glaciers, and they can vary in size and shape depending on the glacier's movement and deposition of material. They are important indicators of past glacial activity and can help scientists understand the history of ice ages and climate change.
