Why don`t I see a terrain?

I don`t see a terrain in Unity. I added a terrain through Create → 3D Object → Terrain. What am I doing wrong? Here is a screenshot:

I tried to press F to focus on it, but everything is in vain I still don`t see it. Help me, please.

Double click on terrain in hierarchy view this will centre the terrain in the scene view, then use your mouse scroll wheel to zoom in.
