Materials, such as sand and rocks, are constantly being added to land masses through the process of deposition. Deposition occurs when the weights of the materials are greater than the forces that are transporting the materials.
Jeremiah sets up an experiment to better understand the process of deposition. In his experiment, he places a pile of sand at the top of a tube. Then, he pours water down the tube at varying speeds. Finally, he measures the amount of sand that is deposited throughout the tube.

The answer is the speed of the water

Explanation:

According to Study Island, All of the factors that can change in an experiment are known as variables.

The test variable (independent variable) in an experiment is the factor that is changed or manipulated by the person performing the experiment.

The outcome variable (dependent variable) in an experiment is the factor that changes in response to the test variable (independent variable).

In Jeremiah's experiment, the test variable (independent variable) is the speed of the water. The outcome variable (dependent variable) is amount of sand that is deposited throughout the tube.
