Question

visible light satellite image near-infrared satellite image select the true statements. healthy crops may be identified using near-infrared satellite images. fallow fields look green in the visible light satellite image. in the near-infrared image, bright green regions represent forests. near-infrared satellite images help farmers monitor where crops are growing.

Explanation:

1. Healthy crops may be identified using near - infrared satellite images: Healthy plants reflect a lot of near - infrared light. So near - infrared satellite images can be used to identify healthy crops as they will show up with distinct signatures compared to non - healthy or non - crop areas.
2. Fallow fields look green in the visible light satellite image: From the visible light satellite image provided (even though the fallow field is labeled, in general, fallow fields (fields left unplanted for a season) can have vegetation or soil that appears green in visible light, or this could be a specific case from the image where the fallow field shows green.
3. In the near - infrared image, bright green regions represent forests: Forests have dense vegetation which reflects a significant amount of near - infrared light. So in near - infrared images, areas with dense vegetation like forests will show up with distinct (bright green in this case) signatures.
4. Near - infrared satellite images help farmers monitor where crops are growing: Since near - infrared can distinguish between healthy crops (which reflect more near - infrared) and other areas, it helps farmers identify the regions where crops are growing (and their health).

Answer:

• Healthy crops may be identified using near - infrared satellite images.
• Fallow fields look green in the visible light satellite image.
• In the near - infrared image, bright green regions represent forests.
• Near - infrared satellite images help farmers monitor where crops are growing.
