Asmall mountain stream will have a competence and a capacity than the mississippi river

A "small mountain stream" will have a greater competence and a lower capacity than the "Mississippi River".

Explanation:

Streams flowing down a mountain tend to have more kinetic energy and momentum than the rivers flowing through plains. This increases their competence but at the same time, drains their capacity to convert themselves into larger streams. Most of the Mississippi River's course happens to pass through plains. That is why the Mississippi River has less competence yet more capacity than a "small mountain stream".
