I’m each example, the atmosphere is interacting with another subsystem of earth. Identify the other subsystem

The following are the subsystems that the atmosphere is interacting with, in each of the given examples:

1. Water evaporates in the presence of sunlight: Atmosphere is interacting with the hydrosphere.

2. Volcanoes release a large amount of gases and other matter during eruption: Atmosphere is interacting with the geosphere.

3. Lightning causes nitrogen molecules to be split and carried by rain: Atmosphere is interacting with the geosphere.

4. Plants release water vapor through their leaves during transpiration: Atmosphere is interacting with the biosphere.

Explanation:

All the cycles functional in nature are only possible due to the eternal interaction taking place between the four spheres of Earth, viz.-

I. Atmosphere (comprising of the envelope made up of all the gases surrounding Earth), II. Hydrosphere (comprising of all the water bodies present on Earth), III. Geosphere (comprising of the area covered by land), IV. Biosphere (comprising of all the life forms existing on the planet).
