How do humans interact with the atmosphere?
MakcuM [25]

Answer:

Each day, Earth’s 6.3 billion people interact with the atmosphere in many ways. Jet pilots, for example, fly through the atmosphere and must be intimately familiar with weather patterns. Satellite TV stations send signals through the atmosphere that bounce off satellites and then back through the atmosphere to satellite dishes scattered far and wide. Many of these interactions are invisible and involve gases, heat, or energy waves. The most basic of these interactions is, of course, breathing. In fact, right now as you read these words, you are inhaling oxygen (O2) and exhaling carbon dioxide (CO2). We humans need a steady supply of “clean” air.

Explanation:

Woof that took forever

There

The geosphere affects the atmosphere as soil provides nutrients to plants that then release water vapor into the atmosphere. Furthermore, how do the spheres interact? The 4 spheres are: lithosphere (land), hydrosphere (water), atmosphere (air) and biosphere (living things). All the spheres interact with other spheres. River action erodes banks (lithosphere) and uproots plants (biosphere) on the riverbanks.
