Ice cap - Wikipedia
In glaciology, an ice cap is a mass of ice that covers less than 50,000 km 2 (19,000 sq mi) of land area (usually covering a highland area). Larger ice masses covering more than 50,000 km 2 (19,000 sq mi) are termed ice sheets .

What Is a Polar Ice Cap? - Wonderopolis
Polar ice caps are dome-shaped sheets of ice found near the North and South Poles. They form because high- latitude polar regions receive less heat from the Sun than other areas on Earth. As a result, average temperatures at the poles can be very cold.
Ice cap climate - Wikipedia
An ice cap climate is a polar climate where no mean monthly temperature exceeds 0 °C (32 °F). The climate generally covers areas at high altitudes and polar regions (60–90° north and south latitude), such as Antarctica and some of the northernmost islands of Canada and Russia.
Ice Sheet Quick Facts - National Snow and Ice Data Center
What is an ice cap? Ice caps are miniature ice sheets. An ice cap covers less than 50,000 square kilometers (19,300 square miles) and comprises several merged glaciers. Like ice sheets, ice caps tend to spread out in dome-like shapes as opposed to occupying a single valley or set of connected valleys.
