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 the relationship between climate and human settlement patterns. Areas with harsh climates, such as deserts and polar regions, generally have lower population densities, while regions with more favorable climates often support larger populations.
