Isohyets



Isohyets are lines that connect areas of equal rainfall. In the map above, we can see the various shades of green show the level of precipitation, while the lines flowing around the map are areas where it rains the same amount. These types of maps are helpful in that they can help up find trends in precipitation and be able to predict the amount of rain to come. They can also work to show us things about the land in that we can see how geographic features, such as mountains, can affect rain levels.
