Exploring the Amplify Flowing Lava Model

The video demonstrates a model using hot wax to simulate a lava flow on a sloped surface. The wax, representing lava, flows down the slope, creating a channel as it cools and hardens. This process illustrates how lava can form landforms with distinct channels. The video speeds up the process for observation and explains the formation of the channel in detail.

What does the tilted tub of sand represent in the model?

• A mountain peak

• A riverbed

• A sloped hill

• A flat plain

Why is hot wax used to model lava flow?

• Because it is a thick melted substance that hardens as it cools

• Because it is cold and solid

• Because it is transparent

• Because it is a liquid at room temperature

What happens to the wax as it flows down the slope?

• It evaporates

• It disappears

• It changes color

• It cools and becomes solid on the edges and bottom

What can be observed about the structure of the wax channel?

• It is a single solid block

• It is completely flat

• It has two walls forming a channel in between

• It has no walls

What does the model demonstrate about flowing lava?

• It can turn into water

• It can create a mountain peak
