How does the water on the earth recycle itself

Um... the water cycle. Evaporation, condensation, and precipitation.

It's called the water cycle, and it starts with the sun evaporating the water from the ground, and turning it into clouds, then when the clouds get really big the water vapor attaches to each other, getting too heavy and they fall to the ground as rain. Then it starts all over again.

Is there a picture of the diagram?

The investiture controversy began as a power struggle between pope gregory vii (1072–85) and henry iv, holy roman emperor (1056–1106).[2] a brief but significant struggle over investiture also occurred between henry i of england and pope paschal ii in the years 1103 to 1107, and the issue played a minor role in the struggles between church and state in france, as well.by undercutting the imperial power established by the salian emperors, the controversy led to nearly 50 years of civil war in germany, and the triumph of the great dukes and abbots. imperial power was finally re-established under the hohenstaufen dynasty. historian norman cantor:
