The map you should create is a Physical map.
Physical maps show the landscape and geographical characteristics of a territory. There you can find, rivers, lakes, mountains. The map identifies each one them by different colors so you can understand it much better.
If you want to complement your work, you can use another type of map called Topographic map.
This map is like physical maps, but it includes different landscapes like elevation changes, and uses a variety of symbols to represent human features and physical ones, too.
Most of the time you will find on the maps coordinated systems like latitude, longitude and UTM grids.
