True or false On a weather map, isobars are lines that connect points of equal air pressure, and letters mark fronts.

The first part of the sentence is true: isobars are the lines that connect points of equal air pressure.

The second part is false (so the whole statement is false too): letters just mark points with high and low pressure.

Fronts are also shown by lines: lines with triangles on them

The statement "On a weather map, isobars are lines that connect points of equal air pressure, and letters mark fronts" is FALSE.

The first part of the statement is true, but the last part that mentions how they are marked is false. Then, the complete sentence is false.

While isobars are the lines that join the points of equal atmospheric pressure, generated from mean sea-level pressure reports, the fronts are not marked with letters but with numbers. The atmospheric pressure is measured in hecto-pascals (hpa) which are equivalent to milibars (mbar).

In a weather map, while lines represent isobars, the numbers included along each line represent the atmospheric pressure value of that particular isobar.
