what are the 3 criteria for being a glacier?
530232
A glacier is a perennial accumulation of ice, snow, water, rock and sediment that moves under the influence of gravity. A glacier forms when winter snowfall exceeds summer melting. Many years of accumulation result in compaction of the bottom layers of snow, turning them to ice.

Air masses are classified according to the temperature and moisture characteristics of their source regions. Based on temperature: tropical (warm), polar (cold), arctic (extremely cold).

Characteristics of polar areas include: Climate - long cold winters, with annual temperatures mostly below freezing. Polar areas are often windy, with very little precipitation. Permanent ice caps cover polar landscapes.

TL;DR (Too Long; Didn't Read) Earth's climate can be divided into three major zones: the coldest polar zone, warm and humid tropical zone, and the moderate temperate zone.

An ice cap is a glacier, a thick layer of ice and snow, that covers fewer than 50,000 square kilometers (19,000 square miles). Glacial ice covering more than 50,000 square kilometers (19,000 square miles) is called an ice sheet. An interconnected series of ice caps and glaciers is called an ice field.

Facts about glaciers. Presently, 10 percent of land area on Earth is covered with glacial ice, including glaciers, ice caps, and the ice sheets of Greenland and Antarctica. Glacierized areas cover over 15 million square kilometers (5.8 million square miles).

Global climates are often divided into five types: tropical, dry, temperate, cold and polar. These climate divisions take a variety of factors into consideration, including altitude, pressure, wind patterns, latitude and geographical characteristics, such as mountains and oceans.
