LIFE SCIENCE

Detailed explanation-1: -A closed system is a system in which only energy is transferred with its surroundings. An open system, however, is a system in which both energy and matter can transfer. The earth is a closed system because only energy is naturally transferred outside the atmosphere.

Detailed explanation-2: -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-3: -Earth is a vast flow-through system for the input and output of energy. The overwhelming majority of the input to Earth’s energy budget comes from the Sun in the form of solar radiation, with geothermal and tidal energy rounding out the picture.

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.
