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.

Deposition

The testimony of a party or witness in a civil or criminal proceeding taken before trial, usually in an attorney's office.

Deposition testimony is taken orally, with an attorney asking questions and the deponent (the individual being questioned) answering while a court reporter or tape recorder (or sometimes both) records the testimony. Deposition testimony is generally taken under oath, and the court reporter and the deponent often sign affidavits attesting to the accuracy of the subsequent printed transcript.

Depositions are a discovery tool. (Discovery is the process of assembling the testimonial and documentary evidence in a case before trial.) Other forms of discovery include interrogatories (written questions that are provided to a party and require written answers) and requests for production of documents.

Depositions are commonly used in civil litigation (suits for money damages or equitable relief); they are not commonly used in criminal proceedings (actions by a government entity seeking fines or imprisonment). A minority of states provide for depositions in criminal matters under special circumstances, such as to compel statements from an uncooperative witness and a few provide for depositions in criminal matters generally.

Before a deposition takes place, the deponent must be given adequate notice as to its time and place. Five days' notice is usually sufficient, but local rules may vary. Persons who are witnesses but not parties to the lawsuit must also be served with a subpoena (a command to appear and give testimony, backed by the authority of the court).

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.
