Choose the way in which the Earth's physical features affect people's activities.

1. Location: The physical features of an area, including its geographic location, often heavily influence the human activities that people undertake in the area. If a region is accessible by air and other forms of transportation, it is likely to have more economic activity. Conversely, areas with difficult terrain may have more difficulty establishing infrastructure and other activities. 2. Resources: Physical features such as soil, climate and water availability determine what type of activities can be pursued in a given area. Areas with favorable conditions may be able to support a greater variety of activities such as agriculture, while areas that are dry or otherwise hostile may not be able to support any agriculture or sustain much of a population. 3. Natural hazards: Physical features such as volcanos, floods or other events can cause destruction, disruption and destruction of infrastructure, ultimately affecting how people live and work in an area as well as the types of activities they can undertake. Hazardous conditions may limit or impair the activities that can be pursued in an area, or may require extensive resources to mitigate the risk.
