| q | It is useful to examine horizontal pressure differences across
space. |

| q | Pressure maps depict isobars, lines of equal pressure. |

| q | Through analysis of isobaric charts, pressure
gradients are |
||||||
| apparent. |
|||||||
| q | Steep (weak) pressure gradients are indicated by closely (widely) |
||||||
| spaced isobars. |
