Question

Aisha wonders whether wind or water causes the most erosion. She set up an experiment in which she used a watering can to pour water down a pile of dirt. She then used a fan to blow wind on a second pile of dirt that is the exact same shape and size as the first pile of dirt. Aisha then measured how the height of the dirt piles changed. She also drew pictures of how their shape changed. In this experiment, what was the dependent variable?

Answer 1

The dependent variable in this experiment was the size of the dirt piles (erosion). 

Answer 2

The correct answer is "The height and shape of the dirt piles"

Step-by-step explanation:

A dependent variable is a variable in an experiment that is passively observed. The dependent variable is affected by the independent variable.
