Question

if earth was not spinning, there could still be a

a. ferrel cell

b. hadley cell

c. seasonal cycle

d. diurnal cycle

Explanation:

• Ferre l cell: It is influenced by the Coriolis effect (related to Earth's spin), so without Earth spinning, it wouldn't exist.
• Hadley cell: Primarily driven by solar heating at the equator. While Earth's spin modifies it (through the Coriolis effect), the basic concept of warm air rising at the equator and moving pole - ward (the essence of Hadley cell) could still occur without spin (though the circulation pattern would be different in terms of east - west movement).
• Diurnal cycle: Caused by Earth's rotation (spin) leading to day - night changes. Without spin, there would be no diurnal cycle.
• Seasonal cycle: Caused by Earth's tilt and its orbit around the Sun, not by its spin.

Answer:

C. seasonal cycle
