because the rocks are all different sizes
The term "till" is the name given to unsorted rocky debris formed by melting glaciers.
Till could be referring to a shortened version of until, or a glacial till which is unsorted glacial sediment.
Unsorted rocky debris that is formed during the melting of a glacier is known as a till. When there are many tills that are present the sediment that is deposited forms a till plain.
till is the name of the material. In most cases all glacial-related deposits are unsorted and unstratified.
glacial till is the stuff deposited from a glacier.

Glacial till or 'Moraine'.

Unsorted rock material that is deposited directly by a melting glacier.
The retreating glacier leaves behind linear mounds of till (till being unsorted debris) and is known as moraine.
The accumulation of unsorted rocky debris that is formed by a melting glacier is called a moraine. There are many large moraines throughout the northern parts of North America, Europe, and Asia.

Unsorted rocky debris that is formed by a melting glacier is called moraine. There are many different types of moraine depending on where the debris is found and deposited.

unsorted and not layered :)
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.
