Astrobiology and Habitability starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Astrobiology and Habitability.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
Describe the concept of panspermia in astrobiology.
Describe the Fermi Paradox in the context of astrobiology.
Describe the greenhouse effect and its importance for planetary habitability.
Describe the main difference between astrobiology and exobiology.
Describe the role of extremophiles in the study of astrobiology.
Explain the significance of the discovery of extremophiles on Earth for the search for life elsewhere in the universe.
A planet has a mass twice that of Earth and a similar composition. Would you expect it to retain a thicker atmosphere than Earth? (Yes or No)
A planet orbits a star at a distance where the equilibrium temperature is 280 K. Is this temperature within the range for liquid water to exist? (Yes or No)
Which molecule is most commonly used as a biosignature in the search for extraterrestrial life? (1) Oxygen, (2) Methane, (3) Carbon dioxide, (4) Nitrogen
Which of the following best describes a planet’s habitable zone? (1) The region where temperatures allow for liquid water, (2) The region closest to the star, (3) The region with the most sunlight, (4) The region with the highest gravity
Which of the following best explains why Titan, Saturn’s moon, is of interest to astrobiologists? (1) It has a thick nitrogen atmosphere, (2) It has lakes of liquid methane and ethane, (3) It has organic molecules, (4) All of the above
Which of the following is a limitation of using oxygen as a biosignature? (1) Oxygen can be produced abiotically, (2) Oxygen is only present on Earth, (3) Oxygen is not detectable, (4) Oxygen is not important for life
