A Model

How does a stream table help scientists and students learn?

Variables

There are different factors that affect the amount of erosion that takes place in a particular area or in a model. These factors are called variables.

What variables affect erosion on the Earth or in a stream table model?

• the tilt of the table or elevation of an area

• the amount and speed of the water

• the amount of vegetation (Plants)

• the type and amount of soil

• Air speed is also a variable (Earth

Multiple Choice

True or False:

Using a stream table: the amount of erosion can be measured by collecting the soil that is carried to the end of the table by the water.

• True

• False

Multiple Select

In a model of erosion, the variables include (Choose all of the correct answers):

• the tilt of the table

• the amount and speed of the water

• the amount of vegetation

• the type and amount of soil used.

• There are no variables.
