Moraine are the rock and soil debris deposited on the surface of a glacier by avalanches and landslips.
Those at the edges (the first formed) are Lateral moraine.
Those at the terminus of the glacier are Terminal moraine.
Where two glaciers join, then their lateral moraines join to become a Medial moraine, i.e. 'middle'.
The moraine overburden lodged towards the head of a glacier, tends to slip down the schrunds and is a major erosive component in the abrasive action.
Where the glacier travels over a step in its bed, an ice-fall is created, marked by a crevasse jumble, and into this much other moraine is embedded into the traveling glacier.
It is remarkable to realize that most of the cross-section of the U-shaped of a glacier's valley has been removed by abrasion - converted into rock flour.

What type of moraine forms along each side of a glaicer?
There are many types of moraines. These include medial moraine, lateral moraine, ground moraine, and terminal moraine. The type that forms along each side of a glacier is a terminal moraine. The one that forms from unsorted rock materials is called a medial moraine.
How do drumlin medial moraine form?
Could be at the edges, but more likely to be a terminal moraine formation. These mounds are just the irregular clumping of clayey moraine material, and their formation is contributed to by the iceblock - caused kettles between them. Note, Terminal Moraine is likely to have lots of clayey material in it from the ground rock flour from the glacier base. Subsequent river/stream erosion into this material is likely to leave tall near-vertical rubble cliffs.
Is a moraine sorted or unsorted?
A moraine is unsorted. Plucking and abrasion by glaciers do not discriminate in size of material debris. It might grind rock matter into what is called "rock flour" and this may be visible at the snout of a glacier, but this and other debris of any size will be be deposited as unsorted till in the form of an end moraine (terminal moraine). A moraine between 2 glaciers is a medial moraine, a moraine along side the glacier is a lateral moraine. Sometimes till can contain glacial erratics... that is, material that came from very far away and does not fit with other materials in the till deposit. Glaciers act as a conveyor belt depending on budget, and material moves with the plasticity of the ice. I hope this helps a little bit.
Why is a terminal moraine important to people?
A terminal moraine, also called end moraine, is a moraine that forms at the end of the glacier called the snout. Terminal moraines mark the maximum advance of the glacier.
How does a moraine form?

Which type of moraine forms along each side of a glacier?
A medial moraine.
What type of moraine is not oriented perpendicular to the direction of ice flow?
medial
What are the common of four moraines?
A moraine is another name for glacial sediment. There are four common types: Lateral, Terminal, Medial and Ground Moraine.
What are facts about Moraines?
The Kaskawulsh glacier in the Kluane National Park, Yukon has a ridge of medial moraine 1 km wide
What is the term for glacier sediment?
The rock and soil debris accompanying the glacier is moraine. lateral moraine at the sides where avalanches have dropped it, terminal moraine where the glacier finishes, and medial moraine formed from the lateral moraines of two contributory glaciers when they join.
How do drumlin medial moraine form?

These mounds are just the irregular clumping of clayey moraine material, and their formation is contributed to by the iceblock - caused kettles between them.
