The thick layer of ice produces the polished look on solid rock by scraping the rock as it moves over it
Rock is polished, either naturally, or by human activity, by abrasion or tumbling action.
Mechanical weathering for example freeze-thew process or abrasion.
Because the glacier moves to slow to be noticed without instruments
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.
Two major erosional processes occur at the base of a glacier. First, at the base of a glacier, large amounts of loose rock and sediment are incorporated into the moving glacial ice by partial melting and refreezing. The second process of erosion involves the abrasive action of the held rock and sediment held by the ice on the surface underneath the glacier. This abrasive process is known as scouring.

Polished
The word "tarnish" in the sentence "the silver will tarnish if it is not polished often" is a verb. It is describing the action of the silver in the sentence.

"The dichotomy between thought and action is profound, in that thought produces nothing, whereas action produces something".

glacial moraine is the debris of rock and gravel brought down a mountain by the action of the glacier and deposited at it's foot.Melt water also forms the head waters of a river
Adhesion produces capillary action. Capillary action is liquid's ability to flow in narrow spaces without external forces like gravity.
Corries or Cirques are bowl like hollows in a mountain range, formed by the action of a small glacier.
Mechanical weathering for example freeze-thew process or abrasion.

A U-shaped valley is considered a glacial landform resulting from the erosive action of a glacier. It is classified as a destructive force as the glacier carves and deepens the valley by plucking, abrasion, and glacial erosion.
