Imagine a leaf floating down the river. Present in the image is a leaf, water, and rocks. Which of these objects has the most density: the lead, the water in the river, or the rocks at the bottom of the river? Put the 3 objects in order starting with the least dense object at the top and finishing with the most dense object at the bottom.

Question

Rocks at the bottom of the river
The water in the river
The leaf

Answer 1

To order the three objects by density from least dense to most dense, we have:

1. The leaf (least dense)
2. The water in the river
3. Rocks at the bottom of the river (most dense)

So, the order is:

1. The leaf
2. The water in the river
3. Rocks at the bottom of the river
