I gave my students this multiple choice question: Surface mining for coal involves removing all the vegetation and rock above the coal being mined. Which two of Earth's subsystems are most immediately affected by surface mining?

Only one answer is correct among these 4 choices:
- lithosphere and atmosphere
- biosphere and hydrosphere
- lithosphere and biosphere
- atmosphere and hydrosphere

Could you tell me which one is correct?

lithosphere and biosphere
