Study Figure 2.12 and say whether the following are true or false. If false, write
a correct statement.
1. Polar fronts are found at approximately 60°N and 60'S where air masses
from the Polar and Ferrel cells meet.
(1)
2. Air masses diverge at the ITCZ at the equator.
(1)
3. Air rises at the poles, leading to divergence.
(1)
4. At 30'N a high pressure belt occurs where alr circulation in the Ferrel
and Hadley cell subside.
5. Subsiding air at the ITCZ results in towering cumulonimbus clouds
causing heavy rainfall.
