Question

questions 2 through 4 refer to the following.
the diagram below is an illustration of global atmospheric circulation
3 mark for review
which of the following is the source of energy driving the circulation pattern labeled c in the diagram?
a the coriolis effect
b solar radiation
c earths magnetic field
d the spinning core of earth

Explanation:

To determine the energy source for the circulation pattern labeled C (Hadley cells, near the equator), we analyze each option:

• Option A (Coriolis effect): Influences wind direction, not the energy source.
• Option B (Solar radiation): Heats the equator more than poles, creating temperature differences that drive atmospheric circulation (including Hadley cells).
• Option C (Earth’s magnetic field): Protects from solar wind, not related to atmospheric circulation energy.
• Option D (Spinning core): Drives Earth’s magnetic field, not atmospheric circulation.

Thus, solar radiation is the energy source.

Answer:

B. Solar radiation
