3. 3.

   What do DEMs stand for?

   • Digital Elevation Models
   • Dynamic Earth Models
   • Digital Environmental Maps

   Hint

   Consider the purpose of elevation in geography.

4. 4.

   True or False: DEMs can help predict landslide risks.

   • True
   • False

   Hint

   Think about the role of modeling in assessing risks.

5. 5.

   You are tasked with a project in a hilly area at risk of landslides. How would you integrate DEMs into your assessment and planning process?

   Hint

   Think about all the steps from data collection to community safety.

6. 6.

   You find that an area has become more prone to landslides due to increased rainfall. Explain how you would use DEMs and time-series data to approach this issue.

   Hint

   Consider both the formation of new maps and the analysis of existing data.
