Describing plants or animals that thrive in hot and dry conditions.
Cacti are xerothermic plants that can survive in desert environments.
Xerothermic is formed from "xero-" (from Greek "xēros", meaning dry) and "thermic" (from Greek "thermē", meaning heat). The word describes conditions that are both dry and hot, typically referring to a climate or environment.
Think of 'dry' ('xero-') and 'heat' ('thermic') together to remember that xerothermic refers to a hot and dry environment.
