Which field of geography and geographic skills would be involved in using satellite imagery to look for concentrations of artificial lights on Earth's surface at night? (1 point)
• This type of imagery would be useful in physical geography for studying distance decay.
• This type of imagery would be useful in human geography for studying population density.
• This type of imagery would be useful in human geography for studying distance decay.
This type of imagery would be useful in physical geography for studying the distribution of urban environments.
This type of imagery would be useful in human geography for studying population density.
The field of geography and geographic skills involved in using satellite imagery to look for concentrations of artificial lights on Earth's surface at night would be useful in human geography for studying population density. By analyzing the distribution of artificial lights, researchers can gain insights into the spatial patterns of human settlements and identify areas with high population concentrations.
The field of geography that would be involved in using satellite imagery to look for concentrations of artificial lights on Earth's surface at night is human geography. Specifically, this type of imagery would be useful in studying population density and distance decay.
To explain how to get the answer, let's break down the question and the given options:
- Physical geography: This branch of geography focuses on the natural features and processes of the Earth, such as landforms, climate, and ecosystems. While studying the distribution of urban environments could be a component of physical geography, it is not directly related to using satellite imagery to look for concentrations of artificial lights.
- Human geography: This branch of geography deals with the spatial distribution and interactions of human populations, cultures, and activities. In this case, the question explicitly mentions that this type of imagery is useful in human geography.
- Population density: Satellite imagery of artificial lights can help determine the concentration of human settlement in specific areas, which is directly related to population density. Light pollution from cities can indicate densely populated areas, while sparsely lit areas may indicate lower population density.
- Distance decay: Distance decay is the concept that the intensity of interaction between places decreases as the distance between them increases. By analyzing the concentration of artificial lights using satellite imagery, researchers can observe patterns of distance decay in terms of the spread and density of human settlements.
By considering the explanations provided for each option, we can conclude that the correct answer is: This type of imagery would be useful in human geography for studying population density.
