# What is isoline in geography?

Isolines are lines drawn on a map connecting data points of the same value. They are commonly used by geographers. Contour lines, for example, show relief and connect points on the map that have the same height. What are the 3 types of isolines?
Isoline Maps

• Contour line: Joins points of the same height above ground.
• Isobath: Joins points of the same depth below water.
• Isobar: Joins points with the same atmospheric pressure.
• Isotherm: Joins points with the same temperature.
• Isobathytherm: Joins points with the same temperature under water.

Isotherms are lines of constant temperature; isobars are lines of constant pressure; isotachs are lines of constant wind speed. Isobars indicate pressure cells.

What do isobars join?

Isobars are lines on a weather map joining together places of equal atmospheric pressure . On the map the isobar marked 1004 represents an area of high pressure, while the isobar marked 976 represents an area of low pressure. … The closer the isobars are together, the windier it is.
