Final answer:
The statement is true; the horse latitudes are in a zone of high atmospheric pressure, leading to calm winds and clearer skies.
Step-by-step explanation:
The statement that the horse latitudes are in a zone of high atmospheric pressure is true. Meteorologists use weather maps to track and predict weather patterns, which include regions of high and low pressure.
The horse latitudes are subtropical regions located at about 30 degrees north and south of the equator, characterized by high pressure, which tends to cause calm winds and stable weather conditions. In these areas, the sinking motion of air suppresses cloud formation, leading to clearer skies. The high-pressure zones are depicted on weather maps, often denoted with an 'H', and these maps also show isobars or lines of constant pressure.
