Answer:
The true statement about the earth subsystem is:
B. EARTH SUBSYSTEM INTERACT WITH EACH OTHER MAKING LIFE POSSIBLE ON EARTH.
Explanation:
Each of the subsystems on earth are constantly changing and interact at all times in order to allow life to exist, you can realize the first statement by noting that the atmosphere (one of the terrestrial subsystems) does not have the same composition that millions of years ago, currently contains a large amount of ozone in order to counteract the sun's ultraviolet rays and protect life on Earth. On the other hand, subsystems such as the hydrosphere together with the water cycle allows a constant flow of liquid that allows quenching the thirst of the different species, finally, the geosphere allows it to provide clear support so that life can carry out activities typical of its species and last in an environment conducive to its development.
