Ice caps are areas of frozen water or gases that are created by the colder conditions near a planet's poles.

In Earth's case, its tilt compared to its orbit gives us seasons, but the shallow angle of sunlight (plus the higher albedo or reflectivity of snow) means that there are large, permanently frozen ice caps in Greenland and in Antarctica.
