Which of these statements best explains why the atmosphere of today was partly due to the interactions of spheres in the past? plants and animals exchanged carbon dioxide and oxygen with the atmosphere. chemicals released from water formed the atmosphere. the molten magma form water droplets. the increase in fertility of soil around the volcano produce rain.

Plants and animals exchanged carbon dioxide and oxygen with the atmosphere

Explanation:

The atmosphere that we know it nowadays is a result of the interactions that were happening between the spheres in the past. The big game changers were the plants and the animals, as they started to use certain gasses from the atmosphere, keep some of them, release some in the soil or air, thus having a biosphere, geosphere, and atmosphere. Gradually this has resulted in a change of the atmosphere, making it suitable for supporting much larger and more complex organisms, at the same time influencing the soils, and waters, the climate etc.
