How does the intertropical convergence zone (ITCZ) relate to deserts? What will be an ideal response?
Trade winds converging toward the equator feed atmospheric upwelling that rises and moves into the
northern and southern hemispheres. The upwelling is the result of more efficient heating of the Earth
by the Sun in equatorial areas, which produces a warm low-pressure air mass. This area is called the
ITCZ or intertropical convergence zone. The high-level airflow away from the equator eventually
cools and sinks back to Earth at about 30 degrees north and south of the equator as a cool, dry highpressure
air mass. This explains the concentration of deserts at these latitudes.

Evaluate the statement. "Convection occurs because of conduction and radiation at the boundaries of a liquid."
A) This statement is true in the laboratory but not true for Earth processes. B) This statement is false because the three types of heat transfer operate separately. C) This statement is true in the laboratory and for Earth processes. D) This statement is false and should say, "Conduction occurs because of convection and radiation at the boundaries of a liquid."
