Question

fairly constant. all the matter that is currently on earth will not increase or decrease. exceptions like satellites or asteroids have minimal impact.

in terms of energy, the earth is an open system. it receives energy from the sun as sunlight and emits energy as heat back into space. this constant energy exchange with the external environment is a crucial aspect of open systems, influencing the earths climate and supporting life.

which is the best example of a closed system?

astronauts spacesuit

water treatment plant

a desert

Explanation:

A closed system allows energy exchange but not matter exchange with the external environment. An astronaut's spacesuit is sealed to prevent matter (like air) from escaping or entering, while it can exchange energy (e.g., heat with the surroundings). A water treatment plant and a desert both exchange matter with their environments, so they are open systems.

Answer:

astronaut's spacesuit
