Alex threw a stick in a river and watched as the river carried it away. He scooped a pail of water from the river and noticed that a leaf was floating in the pail without moving on the surface of the water. Why did the stick move in the river and the leaf stay still in the pail if it was all the same water?
A.The river water cooled off and lost energy when Alex scooped it up into the pail.
B.There is more water in the river than in the pail so the river could move the stick.
C.The water in the river has enough energy to move the stick since it is flowing downhill.
D.Wind could push the stick on the river but could not get to the leaf protected in the pail.
