What is a broad ramp like accumulation of sediment found downstream from the end moraine of a glacier?

A broad ramp-like accumulation of sediment found downstream from the end moraine of a glacier is called a glacial outwash plain. This feature forms as meltwater from the glacier carries and deposits various sediments, including sand and gravel, in a fan-shaped area. The outwash plain typically has a gentle slope and is characterized by stratified layers of sediment due to the varying flow of meltwater over time.
