Moraine may also form by the accumulation of sand and gravel deposits from glacial streams emanating from the ice margin. These fan deposits may coalesce to form a long moraine bank marking the ice margin. [11] Several processes may combine to form and rework a single moraine, and most moraines record a continuum of processes.
Terminal moraine of Wordie Glacier, Greenland Map of the Salpausselkä terminal moraines in Southern Finland. A terminal moraine, also called an end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by ...
A moraine-dammed lake, occurs when the terminal moraine has prevented some meltwater from leaving the valley. When a glacier retreats, there is a space left over between the retreating glacier and the piece that stayed intact which holds leftover debris . Meltwater from both glaciers seep into this space creating a ribbon-shaped lake due to the ...

Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
A fluted moraine, also called a fluted moraine surface, is a moraine whose surface exhibits numerous glacial flutes. The long axes of these flutes are parallel to the flow direction of the glacier. The long axes of these flutes are parallel to the flow direction of the glacier.
The Oak Ridges Moraine probably formed in the Late Wisconsin glacial period. Ice melt from the Niagara Escarpment flowed into the western boundaries of the moraine, wherein conduits beneath the ice expanded to form a west-to-east passage between the main Laurentide Ice Sheet and a mass of ice in the Lake Ontario basin.
A washboard moraine, also known as minor or corrugated moraine, is a geomorphic feature caused by glaciers. The name "washboard moraine" refers to the fact that, ...
The major part of the Kettle Moraine area is considered interlobate moraine, though other types of moraine features, and other glacial features are common. [1] The moraine is dotted with kettles caused by buried glacial ice that calved off the terminus of a receding glacier and got entirely or partly buried in glacial sediment and subsequently ...
