It is due to greenhouse effect.
light ray or energy ray from the sun comes earth and the atmospheric layers stops most of the rays coming into the earth and reflect back them in space.The temperature is mainained due to this and doesnt go on increasing continuously. and due to rotation of earth on its axis a particular part does not get continous heat and hence cool down when opp to sun
