Explanation:

Population distribution means the pattern of where people live. World population distribution is uneven. Places which are sparsely populated contain few people. Places which are densely populated contain many people. Sparsely populated places tend to be difficult places to live. These are usually places with hostile environments e. g. Antarctica. Places which are densely populated are habitable environments e. g. Europe.
