EVERYDAY SCIENCE

Detailed explanation-1: -It is accepted science that the Earth is an open system for energy. Energy radiates into the Earth’s system, 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 ozone layer.

Detailed explanation-2: -With respect to energy, Earth is an open system. Sunlight energy flows in and heat energy escapes. ENERGY FLOWS: The functioning of our planet relies on a constant input of energy from the sun. This energy leaves Earth in the form of heat flowing to outer space.

Detailed explanation-3: -Types of systems: Isolated: no matter or energy enters or leaves. Closed: energy enters and leaves but material does not. Open: both energy and matter enter and leave. The Earth is a closed system: energy from sunlight enters. and “no” matter enters or leaves (except for the rare meteorite)

Detailed explanation-4: -The Earth’s atmosphere, oceans, and land surface act as an almost closed system. Water moves along a variety of pathways in this closed system. This system of movement is called the “water cycle.” There is one main loop in the water cycle.
