最佳解答:
Ans 1) 1Source of Energy 2.Keep the Earth at suitable temperature for life process to occur Ans 2) The blanket trap a layer of air between body and blanket. As air is a poor conductor of heat,it reduce the effect of conduction.Hence,it can keep us warm Ans 3)the blanket of air around the Earth is called atomsphere It can block UV light from entering the Earth.In addition, atomsphere trap re-radiated radiation,this help to maintain a suitable temperature for life process to occur Beside,it is important for transmittion of radio wave(TV broadcasting)
