Question

which of the following scenarios illustrates an interaction between the hydrosphere and the atmosphere?
a. an earthquake causing a tsunami
b. clouds in the sky
c. photosynthesis in plants
d. humans mining coal

Explanation:

• Option A: An earthquake (geosphere) causing a tsunami (hydrosphere) is an interaction between geosphere and hydrosphere, not hydrosphere and atmosphere.
• Option B: Clouds form when water from the hydrosphere evaporates into water vapor, which condenses in the atmosphere. This directly shows an interaction between the hydrosphere (water source) and atmosphere (where clouds form).
• Option C: Photosynthesis involves biosphere (plants) interacting with atmosphere (carbon dioxide intake, oxygen release) and hydrosphere (water uptake), but it is primarily a biosphere-focused interaction.
• Option D: Humans mining coal is an interaction between biosphere (humans) and geosphere (coal deposits), unrelated to hydrosphere-atmosphere interaction.

Answer:

B. Clouds in the sky
