Some plains and some hills are covered with trees. If you were in the woods, surrounded by trees, how would you know whether you were on a plain or on a hill?

Some hills look very different from others. Some slope very gradually, while some are very steep. Some hills have city streets on them. Others have great fields of grass for cows to graze upon. Still others are planted with corn, wheat, rye or vegetables. There are wooded hills covered with trees. How do we know that these different forms are hills?
In the same way plains vary greatly. While some have been made into city streets, others are large, flat, grassy fields, with streams sometimes flowing through them. Some plains are covered with forests. Others are planted with grain and vegetables. How can you know when you see a plain if there are so many different kinds?
