Question

review what you learned after reading pages 82 - 85 of your textbook, answer the following questions about satellite imagery and scientific discoveries to review what you learned. 1. define remote sensing in your own words. 2. what can be seen about an animal in a satellite image? what cannot be seen? 3. what type of scientists work together to interpret the information from satellite images? what do they each specialize in? 4. what is a pixel? what two words is it a combination of? 5. study the images in figure 4.29 on page 83 of your textbook. what do the images represent? how do they differ from one another? 6. how did satellite imagery and the tagging of the black - footed albatross lead to a surprising discovery?

Explanation:

1. Remote sensing is the acquisition of information about an object or phenomenon without making physical contact. It often uses sensors on satellites or aircraft to detect and monitor changes in the Earth's surface.
2. In a satellite image, the general location, size, and shape of an animal can be seen if it is large - enough. However, details like the animal's internal organs, its behavior in real - time (such as eating or sleeping), and its exact species in some cases cannot be seen without further analysis.
3. Geologists, biologists, and meteorologists may work together. Geologists specialize in the Earth's physical structure and processes, biologists in living organisms, and meteorologists in the atmosphere and weather.
4. A pixel is the smallest addressable element in a digital image. It is a combination of "picture" and "element".
5. Without seeing the specific images in Figure 4.29, in general, satellite images can represent different land cover types (e.g., forests, water bodies, urban areas), and they may differ in terms of resolution, color - coding, and the time of acquisition.
6. Satellite imagery and tagging of the Black - footed Albatross likely allowed scientists to track the bird's migration patterns. A surprising discovery could have been an unexpected breeding ground, a new migration route, or an unanticipated habitat use.

Answer:

1. Remote sensing is obtaining information about something without direct physical contact, often using satellite - borne or airborne sensors.
2. Can be seen: general location, size, shape (if large enough). Cannot be seen: internal organs, real - time behavior, exact species in some cases.
3. Geologists (specialize in Earth's structure and processes), biologists (specialize in living organisms), meteorologists (specialize in the atmosphere and weather).
4. A pixel is the smallest element in a digital image. It is a combination of "picture" and "element".
5. Without seeing the images, they can represent land cover types and may differ in resolution, color - coding, time of acquisition.
6. Likely revealed unexpected migration patterns, breeding grounds, or habitat use.
