           For Assertion& Reason question follow the following directions.
           (a) If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
           (b) If both Assertion and Reason are correct, but Reason is not the correct explanation of
           Assertion
           (c) If Assertion is correct but Reason is incorrect
           (d) If Assertion is incorrect but Reason is correct
           (e) If Assertion & Reason both are incorrect
               1.    A student observed water droplets forming outside a cold
                    glass of water. Which step of the water cycle does this best
                    represent?
                            a)  Evaporation
                            b)  Condensation
                            c)  Precipitation
                            d)  Infiltration




               2.    If the amount of freshwater on Earth suddenly decreased, what would be the most
                    immediate effect?
                            a)  Oceans would dry up
                            b)  Aquatic animals would migrate to land
                            c)  Drinking water would become scarce for humans and animals
                            d)  Rainfall would stop completely
           Picture-Based Questions

               3.    Observe the picture and
                    answer the questions:
                        a)  What is the name of the
                            water conservation
                            method shown in the
                            image?
                        b)  How can this method help
                            reduce the impact of a
                            drought?



               4.    The Water Cycle
                    Observe the diagram of the water cycle and fill in the missing processes:
                    (Use these words: Sunlight, Evaporation, Transpiration, Condensation, Precipitation,
                    Collection, Infiltration)

                    Fill in the boxes in the diagram:
