“The composition of the environment is understood based on four large spheres that each contain specific fundamental dynamics for life and for maintaining the environmental balance. It is also important to remember that these spheres are by no means isolated from each other. Quite the contrary, it is their coexistence and interdependence that characterize and define the environment.”

The large spheres that make up the environment are: hydrosphere, atmosphere, lithosphere and biosphere.
Mark the alternative that correctly indicates the characteristics of one of the spheres of the Earth.
a) Hydrosphere: this is a thick layer of gases that form an envelope on our planet, consisting of elements such as oxygen, carbon dioxide, nitrogen and others, in addition to water vapour.
b) Atmosphere: consists of the set of all existing ecosystems on our planet, which includes the most diverse forms of life that inhabit the Earth in terrestrial, freshwater and saltwater environments.
c) Lithosphere: is the outermost layer of the planet Earth, lying above the terrestrial magma. It is divided into very extensive solid fragments called tectonic plates, being formed essentially by rocks and minerals.
d) Biosphere: represents all bodies of water (fresh or salty) on planet Earth. Furthermore, it encompasses water in any physical state: solid, present in the form of glaciers and polar ice caps; liquid, such as seas, rivers, lakes, surface and subsurface waters; and also gaseous, which corresponds to the water present in the atmosphere in the form of vapour.
