Habitability

What is the best place to look for habitable planets?

• Around giant, hot stars

• Around small, cool stars

• Around sun-like stars (average size and temperature)

• Around white dwarfs

Future missions will use telescopes to sense the reflected light of exoplanets. What biosignatures will these missions search for?

• carbon dioxide, sulfuric acid

• methane, nitroxide

• glucose, sulfur dioxide

• water vapor, oxygen, ozone

What is the Moon's most important role in making the Earth habitable?

• causing tides

• stabilizing Earth's axial tilt

• causing seasons on Earth

• blocking Earth from the sun's UV rays

Finding oxygen or ozone in another planet's atmosphere would be an indication that what process is occurring?

• volcanic activity

• plate tectonics

• the burning of fossil fuels

• photosynthesis

Which of the following is NOT criteria to be considered a viable candidate.

• Revolves around a Sun-like star

• Rotates counter-clockwise

• Located in a habitable zone

• Similar size to Earth

Is it possible for an planet to spin too fast for life to exist?

• Yes

• No

What is the role of a planet's magnetic field in maintaining habitability?

• protecting the atmosphere from solar wind

• generating heat

• producing light

• creating tides

Which of the following is a reason life can exist on Earth?

What is the only celestial body that has liquid water naturally available?

• Mars

• Earth

• The Moon

• Phobos (one of Mars' moons)

Why is Earth able to maintain liquid water on its surface compared to Mars and Mercury?

• Earth is at an optimal distance from the sun, allowing for moderate temperatures.

• Earth is closer to the sun than both Mars and Mercury.

• Earth has a thicker atmosphere than Mars and Mercury.

• Earth's distance from the sun makes it from have extreme temperatures like Mars and Mercury.
