What are ocean currents?
movements caused by differences in temperature of sea water
What are the three parts of a course?
Upper course, middle course and lower course

Any 2 of the following;
- The channels run through deep river valleys

- The river basin is small and the relief is mountainous.
- The flow regime is regular and abundant because it rains all year

The source is in the Iberian mountain chain.
