WebJun 6, 2024 · The glaciers form from the accumulation of frozen precipitation (primarily snow) of thousands to millions of years. As frozen precipitation accumulates, it compacts (degases) into solid, clear blue, glacial ice. Although ice is a solid, under pressure it deforms and fractures easily. Ice on the surface of a moving glacier is highly fractured. WebRepetition of this process can create a series of marine terraces that stair-step up a relatively straight coastline as depicted in Fig. 19.5. In addition to shoreline uplift, a marine terrace can also form if a wave-cut platform develops during a high sea level stand, and is subsequently left high and dry following a drop in sea level.
