Most Moroccans inhabit the Atlantic coastal plain. Morocco has many rivers, which, although unimportant for navigation, are used for irrigation and for generating electric power. The chief rivers are the Moulouya, which drains into the Mediterranean Sea, and the Sebou, which flows into the Atlantic Ocean. A. Climate Along the Mediterranean, Morocco has a subtropical climate, tempered by oceanic influences that give the coastal cities moderate temperatures. Toward the interior, winters are colder and summers warmer.
Rain falls mainly during the winter months.
Precipitation is heaviest in the northwest and lightest in the east and south. B. Natural Resources Morocco's resources are primarily agricultural, but mineral resources are also significant. The mountainous regions of Morocco contain extensive areas of forest, including large stands of cork oak, evergreen oak, juniper, cedar, fir, and pine. Except for areas under cultivation, the plains are usually covered with scrub brush and alfa grass. On the plain of Sous, near the southern border, is a large forest of argan, thorny trees found principally in Morocco.
