1 answer

The correct statement about human interaction with Earth's spheres is:

Humans need oxygen from the atmosphere to survive.

This statement accurately reflects the relationship between humans and the atmosphere. The other statements are incorrect:

  • Humans are part of the biosphere, not the geosphere, and they certainly interact with both the geosphere and other spheres.
  • The assertion that humans have no harmful effects on Earth's spheres is false; human activities significantly impact the environment.
  • The statement that humans have no interaction in any of the Earth's spheres is also incorrect, as humans interact with the atmosphere, hydrosphere, geosphere, and biosphere in various ways.
