Question

Earth is an open system for
A. Minerals
B. Energy
C. Gases
D. Water

Answer 1

Hint: An open system includes the transfer and the exchange of both the matter and the energy with the system's surroundings. All of the systems on Earth are classified as open systems.
However, the Earth system as a whole is considered a closed system because there is a limit to how much matter is exchanged.

Complete answer: It is accepted science that the Earth is an open system for energy. Energy radiates into the system of earth, mainly from the sun. Energy is then radiated back into space from the Earth, with the flows being regulated by the Earth's atmosphere and the ozone layer.
The open system is defined as a system wherein there is the free exchange of both matters and energy with the surroundings. The system has interaction with the external environment. All the systems on Earth are called open systems. Earth is an open system for energy.
Therefore, the correct answer is option B.

Additional information:
An open system is contrasted with the concept of an isolated system which exchanges neither energy, matter, nor information with its environment. An open system is also known as the flow system. The concept of an open system was formalized within a framework that enabled one to interrelate the theory of the organism, thermodynamics, and the evolutionary theory. This concept was expanded upon with the advent of information theory and the subsequent systems theory. Today the concept has its applications in the natural and in the social sciences.

Note: The solar radiation passes through the atmosphere and it is absorbed by the ocean.
The absorbed energy evaporates the water from the ocean. All of the "spheres" of the earth system are considered as the open system because the energy and the mass are exchanged between them.
