1.	Question : Give scientific reasons for the following statements : Though hydropower is renewable source of energy, it creates certain problems.
Answer» Solution :Hydropower is renewable source of ENERGY because water gets refilled in reservoir during RAINING. `rarr` High-rise dams are constructed to generate hydroelectricity. `rarr` Such dams are constructed in hilly areas causing ENVIRONMENTAL changes. `rarr` Large eco-systems are submerged under water and destroyed. `rarr` The submerged vegetation DECAYING anaerobically releases large amount of greenhouse gas, i.e., methane. `rarr` Large areas of agricultural land is also submerged. MANY natives are thus displaced. `rarr` Rural-tribal human races may lose their habitat. So, Hydropower plant construction creates certain problems.
