Water Flow and Landform Modeling

What type of model is being used in this experiment?

• A computer model

• A physical model

• A mathematical model

• A conceptual model

The physical model is referred to as a "water table" because it allows observation of:

• How water is stored underground.

• How water affects the shape of land.

• The depth of groundwater.

• The chemical composition of water.

What is the primary purpose of the physical model being built?

• To study the formation of landforms on Venus.

• To understand how water affects landforms on Earth and Mars.

• To demonstrate how to build a computer model.

• To observe the properties of sand.

What material is placed in the plastic dish to simulate land?

• Clay

• Soil

• Sand

• Gravel

What is one of the first noticeable effects when water begins to flow over the sand?

• The sand absorbs all the water.

• The water forms a large, still pond.

• Channels begin to form in the sand.

• The sand becomes completely flat.

What happens to the sand as water flows over it?

• It remains completely stationary.

• It moves and gets caught, forming small dams.

• It dissolves completely into the water.

• It floats on top of the water.

How does the water typically find its path through the sand?

• It creates a single, straight path.

• It follows the most difficult path available.

• It finds the next easiest path.

• It spreads out evenly without forming paths.

What is observed when a larger amount of water flows through the sand?

• The channels disappear.

• The channels become less defined.

• The channels become deeper and more defined.

• The sand becomes completely saturated and stops moving.

Do the landforms created by flowing water remain after the water stops flowing?

• No, they completely disappear.

• Yes, they remain even when the water is no longer present.

• Only if the water flow was very slow.

• Only if the sand was very fine.

How are the channels formed by the water described?

• Wide, shallow depressions.

• Short, circular depressions.

• Long, narrow depressions.

• Irregular, scattered mounds.
