Which of the following characteristics of a planet will have the greatest influence on determining whether or not its temperature will be suitable to support life?

• The amount of its gravitational force.

• The number and size of active volcanoes.

• The tilt of the axis of rotation of the planet.

• The distance from the Sun of its orbit.

NGSS.MS-ESS2-6

Which of the following data could be collected about a planet in a distant planetary system, which might give scientists information about whether or not life exists on that planet?

• The number of other planets in the system.

• How long the planet takes to rotate.

• The orbit length of the planet.

• The presence of an atmospheric ozone layer.

NGSS.HS-LS4-5

If Earth were much smaller than it is now, it would not support life because it would not have enough mass to -

• collect needed radiant energy from the Sun.

• maintain a gravitational pull on the Moon.

• have sufficient gravity to hold an atmosphere.

• rotate on its axis once per day.
