Exploring Geology on Mars: Chapter 2, Lesson 2.3

What is the main focus of the flowing lava claim?

• That flowing water formed the channel on Mars

• That flowing lava formed the channel on Mars

• That wind erosion formed the channel on Mars

• That meteor impacts formed the channel on Mars

Why can't actual lava be used in the flowing lava model?

• It is too expensive

• It is too hot and dangerous

• It is too rare

• It is too thick to flow

What substance is used to represent lava in the model?

• Wax

• Water

• Clay

• Sand

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

• A flat plain

• A valley

• A crater

• A sloped hill

What shape does the wax form at the bottom of the slope?

• A spiral

• A straight line

• A fan shape

• A circular pool

What happens to the wax on the edges and bottom as it flows down the slope?

• It evaporates

• It becomes solid

• It changes color

• It disappears

What is the main observation about the landform created by the wax?

• It forms a flat surface

• It forms a mountain

• It forms a channel with two walls

• It forms a crater

Based on the observations, do you think lava could have formed the channel on Mars?

• No, because lava cannot flow on Mars

• No, because the wax model is not accurate

• Yes, because the wax model shows a similar channel formation

• Yes, because lava is similar to water

What should you do if you need to re-watch the flowing lava model to help record your answers?

• Re-watch the video

• Ask a friend

• Pause the video

• Skip the questions

What will you consider in the next few lessons in Chapter 3?

• The atmosphere of Mars

• The climate of Mars

• The history of Mars exploration

• New evidence from NASA about the geologic process on Mars
