Scientists use models of the Sun to better understand how it works. The currently accepted model of the Sun indicates that it has a dense core surrounded by different layers. How is energy transferred from the core of the Sun to its outer layers?

• Energy radiates outward from the core as visible light.

• Energy is carried inward from the outer layers by convection.

• Energy is radiated out from the core first, then carried to the outer layers by convection.

• Energy is carried out from the core by convection first, then radiated to the outer layers.

Patrick wants to create a computer model of the Sun's rotation. Which of the following designs would be the most accurate?

• He should show the Sun rotating at the same rate as Earth.

• He should show the Sun rotating more rapidly at its equator than at its poles.

• He should show the Sun rotating and revolving in exactly the same period of time.

• He should show the interior and exterior of the Sun rotating at the same rate of speed.

Which statement describes sunspots?

• Sunspots have a bright white appearance.

• Sunspots occur in the radiation zone of the Sun.

• Sunspots occur in areas of extremely low magnetic fields.

• Sunspots have lower temperatures than their surroundings.

Scientists have modeled the behavior of the Sun for many years. Some models show how the Sun's magnetic field gets tangled up as the Sun rotates. These tangled magnetic fields can lift extra energy to the surface in an explosive event that releases solar material into space. Which solar event is explained by this model?

• auroras

• flares

• prominences

• sunspots

Energy is created in the core when two _____________ atoms join together to form a ______________ atom.

• helium, hydrogen
• carbon, hydrogen
• nitrogen, helium
• hydrogen, helium
