               CHAPTER-3-Oue Changing Earth
                   1.    Examine how active volcanoes are distributed throughout the planet. How does this
                         distribution relate to the movement of tectonic plates?
                   2.    Compare and contrast the work of sea waves on rocky coastlines. How does the type
                         of coastline affect the patterns of erosion and deposition?
                   3.    Discuss how the action of a river can change the landscape over time. How can these
                         changes impact the local ecosystem?
                   4.    Consider yourself a coastal engineer assigned to safeguard a village that is
                         experiencing severe coastal erosion. Which manmade and natural techniques would
                         you suggest using to reduce wave erosion, and why?
                   5.    Why is wind action more prominent in deserts?
                   6.    Examine the latest techniques for earthquake prediction and intensity measurement.
                         Examine the advantages and disadvantages of various approaches.
                   7.    Share a list of the emergency measures you will take during the tremors of the
                         earthquake.
                   8.    Examine the effects of earthquakes on urban infrastructure, especially in places with
                         high population densities.
                   9.    Make a plan to prevent the water logging problem or minimize the effects of the
                         same if it occurs.
                   10.   Choose a desert region (like the Sahara or Thar Desert) and investigate how wind
                         action shapes its landscape.
