Terrain look

So I’m making a tornado game and the game is going to have two modes, a mode where you can chase the storm and where you are the storm. The problem is that if I add dirt and grass terrain I can see all the squares in the terrain. But then if I make the terrain squares larger it looks reallly good from air view but it looks really stretched from ground view. Is there a way I can fix it so the terrain squares arnt enlarged but arnt noticeable from sky view?
