What the Crater that Impacted the Dinosaurs Taught Us About Mars

What is the primary difference between ejecta blankets on Mars and those on the Moon?

• Moon's ejecta blankets are thicker.

• Moon's ejecta blankets are more turbulent.

• Mars's ejecta blankets have multiple layers with wavy edges.

• Mars has smoother ejecta blankets.

Which hypothesis suggests that Mars's ejecta blankets were formed by a lubricated debris flow?

• Gaseous debris flow hypothesis

• Volcanic eruption hypothesis

• Ballistic trajectory hypothesis

• Lubricated debris flow hypothesis

What significant discovery was made around the Chicxulub crater?

• A new type of asteroid

• Fluidized ejecta blankets similar to those on Mars

• A new species of dinosaur

• Evidence of volcanic activity

How did scientists conclude that the Chicxulub ejecta blanket was fluidized?

• By studying its layered structure

• By observing its color

• By measuring its temperature

• By analyzing its chemical composition

What role does atmospheric turbulence play in the formation of ejecta blankets?

• It prevents the formation of ejecta blankets.

• It has no effect on ejecta blankets.

• It causes the ejecta to evaporate.

• It helps in the layering of ejecta blankets.

What does the model of the Chicxulub impact suggest about the movement of ejecta?

• Ejecta was stationary.

• Ejecta moved in a straight line.

• Ejecta moved upwards.

• Ejecta was overtaken by a turbulent atmospheric flow.

What can diverted flows and eroded material indicate about Mars's past?

• Absence of water

• Presence of volcanic eruptions

• Slower, volatile-rich surface flows

• Presence of life
