1 / 1 pts Question 10 Dr. Karwan use an image of a bicycle to illustrate what concept? (There is more than one answer) The important driving mechanisms for the water cycle are solar radiation and gravity Correct! Correct! Correct! Correct! Water can only go downhill, just like a bicycle Water is like a wheel...it keeps on turning Conservation of mass Correct! Correct! Correct! Correct! Water is neither gained nor lost from the water cycle Correct! Correct! Correct! Correct! Three answers are correct: conservation of mass, water is neither gained nor lost, and the driving mechanisms for the water cycle. 1 / 1 pts Question 11
