1. a forest fire spreads heat to nearby trees through radiation. which spheres are involved?

• a. biosphere and atmosphere
• b. hydrosphere and cryosphere
• c. geosphere and exosphere

Explanation:

• Question 6: Rain (Hydrosphere) falls on mountain (Geosphere).
• Question 7: Plants (Biosphere) take in carbon dioxide from air (Atmosphere).
• Question 8: Ice (Cryosphere) melts into ocean (Hydrosphere).
• Question 9: Volcano (Geosphere) sends ash into sky (Atmosphere).
• Question 10: Forest fire (Atmosphere - heat transfer) affects trees (Biosphere).
