NGSS.HS-ESS1-6

The "Goldilocks zone" refers to a region in space where:

• There is no solar radiation.

• Water can remain in a liquid state.

• Planets are too far from their star.

• Only gases exist.

Why is Earth able to retain water over billions of years?

• High solar radiation

• Earth’s strong magnetic field

• Gravity and low enough temperatures to condense water

• Presence of carbon dioxide

NGSS.MS-ESS2-4

The presence of water is considered essential in the search for extraterrestrial life because:

• All life forms are carbon-based.

• Water is necessary for organic reactions.

• Water can exist on all planets.

• Water is required for photosynthesis.

Which of the following best explains why Earth is in the Goldilocks zone?

• The Sun provides just enough light.

• Earth’s atmosphere reflects harmful radiation.

• Earth is at a distance where water can exist in all three states.

• The Earth rotates quickly, reducing temperature differences.

Which factor most contributes to Earth’s ability to retain water after it was delivered by asteroids?

• The Moon’s gravitational pull

• Earth’s atmosphere

• Earth’s gravity

• Magnetic field strength

NGSS.MS-ESS2-4

Which of the following is true about water in the context of extraterrestrial life?

• Water has never been detected outside Earth.

• Water only exists in gaseous form outside of Earth.

• The presence of water increases the potential for life on other planets.

• Water is less important than carbon in the search for life.

Which of the following events is not directly related to the retention of water on Earth?

• Solar winds stripping the atmosphere

• Earth’s gravitational pull

• Earth’s distance from the Sun

• Asteroid impacts delivering water

What characteristic of water makes it essential for supporting life?

• Its low boiling point

• Its high heat capacity

• Its ability to reflect light

• Its solid form being more dense than its liquid form

NGSS.HS-ESS2-5

Which of the following is a reason for the interest in finding water on other planets?

• Water is required for photosynthesis in plants.

• Water is a universal solvent, critical for chemical reactions in life.

• Water increases the temperature of a planet.

• Water indicates the presence of oxygen.
