coastal plains

Most coastal plains are found five to forty miles inland and some end with jagged cliffs like this one.
Frankincense and myrrh are made by collecting the tree sap from the few trees located on coastal plains.
Some coastal plains around the Arabian Peninsula have natural harbors that form just like this one.
When crops are grown on coastal plains dams are usually built in order to help create irrigation systems to evenly distribute the water among the plants.
