A Glacier will advance when the snow deposited in the collection zone exceeds the rate of melting at the terminus. There will be some time delay between these events, even a steep glacier will take a few years between the events.
In general, ice sliding across rock. Usually applies to glacial movement and its impact on the underlying ground.
Moraine and boulder clay and Glacial outwash are other names of these glacial deposits. But there are subtly different definitions. Best to describe your usage.add But there are other meanings for the word. To till the soil is to cultivate it - to turn it over preparatory to planting. Probably this is the image behind the glacial term.And a till is a cash register - in a shop.

Erosion is the process of the movement of materials from one place to another, and the four agents of erosion are ice, water, wind, and gravity. Two types of glacial erosion are plucking and abrasion
To determine the direction of past glacial movement on the Kingston Quadrangle, I analyzed glacial striations, which are scratches or grooves on bedrock caused by the movement of glaciers. Additionally, I examined the orientation of drumlins and moraines, which are landforms that indicate the flow direction of glacial ice. The alignment of these features consistently pointed toward the southeast, suggesting that the glaciers moved in that direction during their advance.

Glacial striations are long, parallel scratches or grooves on bedrock caused by the movement of glaciers. As glaciers advance and retreat, they can pick up rocks and debris, which then act like sandpaper as the glacier moves, creating these striations on the underlying bedrock. Studying these features can provide information about the direction and extent of past glacial movement.
Glacial striations gouged into bedrock allow geologists to understand the direction of glacial movement and the force of the ice. This information helps reconstruct past glacial activity, study ice flow dynamics, and track changes in climate over time.
the direction of glacial movement 🥶
The direction of movement of a glacier is best indicated by the presence of striations on the underlying bedrock, the alignment of glacial erratics (rocks different from the surrounding bedrock), and the formation of drumlins (elongated hills of glacial sediment). Additionally, the shape of the glacier's terminus and the distribution of moraines can also provide clues about its movement direction.
A characteristic of glacial movement is movement depends on the balance between accumulation and wastage.

A drumlin is a long, narrow hill formed by glacial drift. Drumlins are typically elongated in the direction of glacier movement and have a smoothed, rounded shape.
Glacial advance can decrease sea level because it locks up water in the form of ice on land, reducing the amount of liquid water in the oceans.
