Answer:
Free-thaw cycles = Nonpermanent ice
Tundra = Cold grassy plain
Icecap = Permanently frozen
Highlands = Glacier near the equator
Explanation:
Freeze-thaw cycles occur when water freeze overnight or over a season. Its expansion can create mechanical weathering. While ice caps to retreat and extend during the seasons, they still maintain some ice and remain frozen. Glaciers near the equator will usually only form at high altitudes and therefore will require mountains and highlands to form. Tundra is harsh environments for vegetation to grow but can often have grass that is used for grazing.
