Land and water: the fascinating natural forms all around us.

Can you tell the difference between a bay and a gulf? A mesa and a mountain? Or an isthmus and a peninsula?

All of these are common land and water forms that you will find on maps. The illustration at right shows an imaginary place that includes many of the world's landforms and waterways. Each one has its own special name.

Compare the land and waterways in the illustration with the descriptions below. Then answer the questions.
