Try these first

1. 1.

   What is the role of the energy source in remote sensing?

   Hint

   Think about how photos are taken during the day.

2. 2.

   Name two types of sensors used in remote sensing.

   Hint

   Consider how a camera captures images versus radar.

3. 3.

   What is the essential role of the energy source in remote sensing?

   • It scatters light
   • It provides energy
   • It speeds data transmission

   Hint

   Similar to how sunlight is necessary for photography.

4. 4.

   True or False: Active sensors do not emit their own energy.

   • True
   • False

   Hint

   Think about how radar works.

5. 5.

   How would the data interpretation process differ between passive and active sensors in various weather conditions?

   Hint

   Think about how photography works in different lighting situations.

6. 6.

   Discuss the ethical considerations of data use concerning remote sensing technology in urban areas.

   Hint

   Relate these concerns back to discussions on responsible technology usage.
