Chapter 5 – Atmospheric Pressure and Wind

The ITCZ is:

• a type of computer technology

• a weather phenomenon characterized by a band of clouds around the Earth near the equator

• an international trade organization

• a new programming language

The nature of atmospheric pressure is:

• the force exerted by the weight of air above a surface
