Question

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

Explanation:

1. Near-infrared satellite imagery can detect vegetation signatures, allowing farmers to map crop growth areas.
2. Fallow fields lack dense, healthy vegetation, so they do not appear green in visible light imagery (they typically look brown or bare).
3. Healthy vegetation strongly reflects near-infrared light, making this imagery effective for identifying thriving crops.
4. Bright regions in near-infrared imagery correspond to dense, healthy vegetation (not specifically forests); this could be crops, grasslands, or forests, so the statement is overly narrow and incorrect.

Answer:

• Near-infrared satellite images help farmers monitor where crops are growing.
• Healthy crops may be identified using near-infrared satellite images.
