Here are the correct terms/concepts for each statement: 3.5.1 Global air circulation is the **large** scale circulation of air across the globe. 3.5.2 The Inter-Tropical convergence zone is found along the **Equatorial low** pressure belt. 3.5.3 Trade winds are winds that blow from the sub-tropical high-pressure systems north and south of the equator towards the **equatorial low** pressure system. 3.5.4 The sub-tropical high-pressure zone is commonly referred to as **doldrums**. 3.5.5 A polar high-pressure results from cool descending air that forms a series of high pressures at the **poles**. 3.5.6 Horse latitudes are commonly referred to as an area of **calm** weather conditions. 3.5.7 The planetary wind model refers to circulation that results from air movements from the **equator to the poles**. Thus, the answers are: 1. large 2. Equatorial low 3. equatorial low 4. doldrums 5. poles 6. calm 7. equator to the poles The final expression evaluates to \( 7 \times 1 \times 7 = 49 \).
