The statement that best describes how climate can affect Earth’s human geography is:
"Many climatic regions of Earth have sparse human populations, such as deserts and ice-covered lands. Other climatic regions, such as those with mild temperatures and a lot of precipitation, are densely populated with people."
This statement accurately reflects how climate influences human settlement patterns, with more desirable climates (mild temperatures and adequate precipitation) supporting larger populations, while harsher climates (deserts and ice-covered areas) tend to have fewer inhabitants.
