Question

8/10 how can human activities impact the geosphere? by producing oxygen by blocking radiation by increasing erosion by regulating temperature

Explanation:

• Option "By producing oxygen": Plants produce oxygen, not typical human activities (except for artificial oxygen production on a small scale, not a major geosphere impact).
• Option "By blocking radiation": The ozone layer (a part of the atmosphere) blocks radiation, and human activities like CFC emissions damage it, but this is more about the atmosphere, not directly the geosphere.
• Option "By increasing erosion": Human activities like deforestation, construction, and agriculture can remove vegetation, destabilize soil, and increase erosion rates, which directly impacts the geosphere (the solid part of the Earth including soil, rocks, etc.).
• Option "By regulating temperature": The atmosphere and biosphere play more direct roles in temperature regulation, and human - caused temperature changes (like global warming) are more about the atmosphere - hydrosphere - biosphere interaction, not a direct regulation of temperature by humans on the geosphere.

Answer:

C. By increasing erosion
