Solution(By Examveda Team)

With respect to energy, earth is regarded as Open system.
Earth's atmosphere has no definite boundary, gradually becoming thinner and fading into outer space.
Any system within the Earth system is considered an open system. Because energy flows freely into and out of systems, all systems respond to inputs and, as a result, have outputs.
