One group of students designed an experiment to demonstrate the interaction between Earth spheres. The steps of the experiment are listed below.

• Make a 25 cm high mountain with some soil.

• Use a hose to sprinkle water on the mountain.

• Observe the change in the shape of the mountain.

The experiment most likely demonstrates the interactions between the

1) atmosphere and biosphere

2)biosphere and hydrosphere

3) geosphere and biosphere

4) hydrosphere and geosphere
