Question

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.

What is the test variable (independent variable) in Jeremiah's experiment?

A.
the initial quantity of sand
B.
the speed of the water
C.
the type of tube that was used
D.
the quantity of sand in the tube

Answer 1

B.  the speed of the water

Explanation:

The independent variable here is the speed of the water being poured through the tube.

An independent variable is the variable is the whose change does not rely on another.

• The speed of the water is the cause of the sand deposition.
• This is the independent variable.
• The quantity of sand that is deposited is the dependent variable.
• It relies on the speed of the water.
• The dependent variable is the effect of the speed of water being poured.
