The change over time in Landsat maps that would most likely be associated with contaminated water habitats nearby is the increased size of gray areas.
To determine which change over time in Landsat maps would most likely be associated with contaminated water habitats nearby, we need to understand the colors and their corresponding meanings in Landsat imagery. Landsat images are composed of various bands that capture different wavelengths of light, including visible and infrared light. These different bands provide information about different features on the Earth's surface, such as vegetation, water bodies, and urban areas.
Typically, healthy water bodies appear blue or dark in Landsat images, while contaminated or polluted water bodies may appear as different shades of green, yellow, or brown. To identify changes over time that could indicate contamination in nearby water habitats, look for color shifts or changes in the size or distribution of certain areas in the Landsat maps.
Based on the given options, "increased size of gray areas" would be the most likely change associated with contaminated water habitats nearby. This is because gray areas could represent a water body that has become contaminated and is no longer healthy. If the size of gray areas increases over time, it suggests that the contamination is spreading or becoming more significant.
On the other hand, "gray areas replaced with light green areas" suggests a positive change, where unhealthy or contaminated water bodies are being restored or improved. Similarly, "increased size of dark green areas" implies the expansion of healthy vegetation, which may not necessarily indicate contamination in nearby water habitats. Lastly, "green areas replaced with yellow areas" may indicate changes in vegetation health or different types of vegetation but does not directly correlate with contaminated water habitats nearby.
In summary, the most likely change over time in Landsat maps associated with contaminated water habitats nearby would be the "increased size of gray areas."
