Which of the following best describes the appearance of areas with high moisture in infrared images?

In infrared images, areas with high moisture content typically appear bright or white. This is due to the way water absorbs and reflects infrared radiation. Water has a unique spectral signature in the infrared spectrum, which allows it to be easily distinguished from other land or vegetation types.

When infrared sensors capture data, they detect the energy reflected off surfaces. High moisture areas, such as wetlands, lakes, or even moist soil, reflect a significant amount of infrared light, causing them to appear bright or white in infrared imagery. This ability to identify wet regions using infrared technology has essential applications in environmental monitoring, agriculture, and water resource management.

The other options do not align with how moisture is represented in infrared imagery, making the bright or white appearance the best choice for areas with high moisture content.
