Energy inputs to coastline? Strange question.





a.) I suppose wind, underwater currents, seismic activity.





b.) The length of the coastline and the size of the adjacent body of water determine the size of the input of energy. Land barriers help to absorb and deflect energy.





c.) In a system, all the different parts are interrelated. So if you do something adverse (bad) to the coastline, that might upset the balance of the system.
Reply:sorry im doing my homework cant help, looking it up would be faster than people just guessing and giving you wrong answers.
Reply:Energy forces affecting coastline....would be ice, storms, wind, water (pounding waves/erosion), etc.
