Air circulation patterns within the atmosphere that create wet terrestrial conditions in the tropics and dry conditions at 30oc north and south of the equator.
a. jet stream
b. brady cells
c. hadley cells
d. el nino

The correct answer is C. Hadley cells create wet terrestrial conditions in the tropics and dry conditions at 30º North and South of the Equator.

Explanation:

The Hadley cell is a closed circulation cell of the Earth's atmosphere that dominates the global atmospheric circulation in the equatorial and tropical latitudes.

Hadley's cells extend from the Equator to latitudes of about 30 degrees in both hemispheres. This heat is transported in a cellular movement with the air rising by convection in the equatorial regions and moving towards the upper latitudes through the upper layers of the atmosphere. The rise of hot air in the Equator is accompanied by the frequent formation of convective storms in the so-called intertropical convergence zone.
