Types of Glaciers
An ice sheet is a chunk of glacier ice that covers the land surrounding it and is greater than 50,000 kilometers (20,000 miles) wide. An ice sheet is also known as a continental glacier.
Yes. "Retreating" is a relative term. It means that the glacier is melting faster than it is moving, which results in the glacier getting smaller.
As a result of the pressure from the glacier's weight and a downward slope, the glacier moves slowly along to the low point, generally the ocean. The rocks and outcroppings and uneven ground also tend to slow the glacier down (like sand under your snow tires) but it is not stopped.
Glacier Types: Ice caps. Ice caps are miniature ice sheets, covering less than 50,000 square kilometers (19,305 square miles). They form primarily in polar and sub-polar regions that are relatively flat and high in elevation.
By comparison, Iceland (near the bottom center of this image) is a much smaller land mass, and features ice caps and glaciers. —Credit: Arctic Climate Research group at the University of Illinois Iceland’s Vatnajökull Ice Cap is the largest in Europe.
An iceberg is ice that broke off from glaciers or shelf ice and is floating in open water. Iceberg located in Ross Sea, Antarctica. To be classified as an iceberg, the height of the ice must be greater than 16 feet above sea level and the thickness must be 98-164 feet and the ice must cover an area of at least 5,382 square feet.

Piedmont glacier definition is - a glacier formed by convergence of the ends of valley glaciers at the base of mountains.
Tidewater glaciers are valley glaciers that flow all the way down to the ocean. They often calve numerous small icebergs, which can sometimes pose problems for shipping lanes. Taku Glacier winds through the coastal mountains of southeastern Alaska.

Valley glaciers are streams of flowing ice that are confined within steep walled valleys, often following the course of an ancient river valley. The downward erosive action of the ice carves the valley into a broad U shape, in contrast to the steeper V shape that is produced during the early stages of erosion by rivers.
