an ice shelf is ice that has been compacted by snow and ice for hundereds of years forming its own land and are disapearing at an alarming rate because of global warming

Another Answer

An ice shelf is glacier ice that has flowed into the sea water over thousands of years and not melted. Ice shelfs float on the sea water, but can be hundreds of feet thick.

No one knows what exists under the Ross Ice Shelf, for example.
