Sun Unit

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
