Answer 2

Answer:

1. In aviation and television weather reports, pressure is given in inches of mercury ("Hg), while meteorologists use millibars (mb), the unit of pressure found on weather maps.Meteorologists use a metric unit for pressure called a millibar and the average pressure at sea level is 1013.25 millibars.
2. An isobar is a line on a map that shows a meteorologist what the pressure is at the surface of the earth. They are lines that connect equal points of pressure. Isobars can be used to map atmospheric or air pressure in a way that makes it easier to understand.
