Help with History - Drawing a Map?

My teacher gave us a country to draw and we have to locate several things such as the capitals, the largest river, main cities and I am stuck on one thing this thing called "terrain" I'm not sure what to locate or what to do. I have it on my notes and from what I can tell it's the mountains, forrests, deserts etc but what am I supposed to do? Find the deserts and such and label them on the map?
