How are the Grand Canyon flood investigations similar to the stream-table investigations you did in class and viewed on the online activity? How are they different?

The alterations to which we refer have occurred because the reservoir replaced the natural rhythm of violent summer avenues with a gentle daily alternation of ebb and flow dictated by the demand for electric energy from cities that are many kilometers away. The dam, therefore, eliminated the seasonal variation of the flow and ended with the huge annual floods that rumbled through the canyon.

Explanation:

i think this is somewhat of answer i hope it helps tho

its true: ) hope this

incident infrared radiation is blocked. visible and ultraviolet radiation heat   earth.

earth radiates infrared radiation. infrared radiation is blocked and heats earth. visible and shortwave radiation heat earth.

earth radiates longwave radiation

longwave radiation is reflected downward longwave radiation heats earth
