NGSS.MS-PS4-1

NGSS.MS-PS4-2

A continuous stream of charged particles from the Sun, with variations in the stream causing beautiful aurorae displays (northern lights), as well as geomagnetic storms that knock out power grids on Earth.

• Ozone Layer

• Atmosphere

• Solar Winds

• Sunlight

Magnetic lines of force from Earth’s polar north and south, acting like a giant magnet.

• Magnetosphere

• Atmosphere

• Ozone Layer

• Earth's Magnetic Field

NGSS.MS-PS2-5

An area that deflects and traps harmful particles; resulting from an interaction of Earth's magnetic field with solar "wind" (charged plasma) streaming from the Sun.

• Earth's Magnetic Field

• Magnetosphere

• Atmosphere

• Ozone Layer

Which of the following characteristics of Jupiter best explains why Jupiter does not support life, while Earth does? Jupiter -

• has four moons that orbit the planet.

• has virtually no water on the surface.

• rotates on its axis once every 10 hours.

• orbits the Sun once every 12 years.

NGSS.MS-LS1-5

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.MS-LS2-3

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.
