Final answer:
Three factors that determine a geographic region include latitude, altitude, and climate. Physical factors such as climate and vegetation, along with human factors like cultural diversity and trade networks, contribute to defining a region's characteristics and influence settlement distribution.
Step-by-step explanation:
Latitude, altitude, and climate are three factors that determine a geographic region. Latitude affects temperature and climate patterns due to its influence on the angle of the sun's rays hitting the Earth. Altitude, or elevation, impacts temperature and precipitation, as higher elevations tend to have cooler temperatures and unique precipitation patterns. Climate reflects the overall conditions of temperature, precipitation, and other atmospheric factors in a region, which are influenced by latitude, altitude, and other elements such as wind systems and ocean currents.
Physical and human factors together define the characteristics of a geographic region. Physical factors include climate, vegetation, and terrain, while human factors encompass cultural diversity, population density, ethnic grouping, and trade networks. The interaction between these physical and human factors influences the size and distribution of settlements, as well as the overall identity and functionality of a region.
