it is called an Erratic
A large boulder left behind by a glacier is called a glacial erratic. These erratics are often significantly different from the surrounding rocks, providing clues about the glacier's movement and the rocks it passed over during its journey.
Valley glaciers typically flow down valleys and do not spread out over large islands or continents. They are confined to the topography of the land and move under the influence of gravity. Ice sheets, on the other hand, can cover large landmasses like islands and continents.
The unsorted rocky debris formed by a melting glacier is called moraine. Moraines can come in various forms, such as lateral moraines, medial moraines, and terminal moraines, depending on where they are deposited by the glacier. This debris is a mixture of different rock sizes and types that were picked up and transported by the moving glacier.
A glacier that spreads out over a large expanse of land, such as an island or continent, is referred to as an ice sheet. These ice sheets are massive bodies of ice that cover vast areas of land and can be several kilometers thick. Greenland and Antarctica are examples of regions where ice sheets are found.
This phenomenon is known as an iceberg calving. Iceberg calving occurs when a large piece of ice breaks off from a glacier or ice shelf and floats into the ocean, forming an iceberg. This process is a natural part of the glacier's movement and can be triggered by various factors, such as temperature changes or the ice shelf's structure.

A large boulder.
A crevasse is a large crack in a glacier.
An isolated large boulder (known as an 'erratic boulder') standing in the open, was left there by a glacier, after the ice retreated at the end of an ice age.. They are known as an 'erratic'.
Any large mass of ice that moves slowly over ice is called a glacier.
