I’m each example, the atmosphere is interacting with another subsystem of earth. Identify the other subsystem
alexdok [17]
<h2>The following are the subsystems that the atmosphere is interacting with, in each of the given examples: </h2>

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).
