Suns and Other Stars

Selma is creating a visual representation of the sun and its components for her science fair.Her first illustration shows the three sections of the sun's interior. She labeled the three sections of the interior, but one of the labels fell off the board. Which label is missing? SC.8.E.5.6

• middle zone

• solar flare

• radiative zone

• plasma

In studying the corona layer of the sun's atmosphere, Asher learned that streams of electrically charged particles are emitted from the corona. What is the stream called? SC.8.E.5.6

• solar wind

• photosphere

• plasma

• solar eclipse

Scientists continue to study the sun and learn more about its structure and how it produces heat. In which layer of the sun does the most heat flow in the form of electromagnetic radiation?

• convection zone

• core

• radiative zone

• surface

Energy generated by nuclear fusion in our sun occurs where?

• core

• corona

• chromosphere

• radiation zone

Which of the following sentences best describe the convection zone of the sun? SC.8.E.5.6

• The energy is carry outward to the sun’s surface by the movements of rising hot gases and sinking cool gases.

• The energy is carry outward to the sun’s surface by the movements of sinking hot gases and rising cool gases.

• The energy is carry from the convection zone to the core by electromagnetic radiation.

• The energy that is coming from the core is carry to the convection zone by nuclear fusion.
