The change over time in Landsat maps that would most likely be associated with contaminated water habitats nearby is an increased size of dark green areas.
The change over time in Landsat maps that would most likely be associated with contaminated water habitats nearby is the increased size of dark green areas. To understand why, we need to consider the characteristics of contaminated water habitats and how they might appear on a Landsat map.
Contaminated water habitats often result from pollution or other human activities that negatively impact the water quality. These habitats can lead to the growth of algae or aquatic plants, which can contribute to the formation of dark green areas in the water bodies. This is because excessive nutrients or pollutants can cause an overgrowth of vegetation, resulting in a denser and darker appearance.
To verify this hypothesis, we can analyze Landsat maps over time. Landsat is a series of Earth observation satellites that capture images of the Earth's surface in different spectral bands, including visible and near-infrared wavelengths. The different colors on a Landsat map represent different land cover types, such as vegetation, water bodies, urban areas, etc.
By comparing Landsat maps from different time periods, we can observe changes in the size and appearance of different land cover types. In the case of contaminated water habitats, if the water quality deteriorates over time, we would expect to see an increase in the size of dark green areas on the Landsat map. This change would indicate the expansion of the affected water habitats and the potential presence of contamination.
Therefore, the answer to the question is "increased size of dark green areas." This change would suggest a correlation with contaminated water habitats nearby.
