Unit 7: The Sun Vocabulary Quiz

the lower part of the Sun's outer atmosphere that lies directly above the Sun's visible surface

• Photosphere

• Chromosphere

• Corona

• Convective zone

the region immediately below the Sun's visible surface in which its heat is carried by convection.

• Photosphere

• Chromosphere

• Convective zone

• Radiative Zone

The outer, hottest part of the Sun's atmosphere.

• Photosphere

• Corona

• Toposphere

• Chromosphere

texture seen in the Sun's photosphere. Granulation is created by clumps of hot gas that rise to the Sun's surface.

• Sunspots

• Granulation

• Prominence

• Flares

the condition in which pressure and gravitational forces in a star or planet are in balance. Without such balance, bodies will either collapse or expand.

• Hydrostatic equilibrium

• Ideal gas

• Thermal equilibrium

• Gravitational equilibrium

tiny neutral particles with little or no mass and immense penetrating power. These particles are produced in great numbers by the Sun and other stars as they fuse hydrogen into helium, and also by supernova

• Protons

• Positrons

• Neutrinos

• Neutrons

The visible surface of the Sun.

• Chromosphere

• Photosphere

• Corona

• Ionosphere

a cloud of hot gas in the Sun's outer atmosphere. This cloud is often shaped like an arch, supported by the Sun's magnetic field.

• Solar flare

• Prominences

• Sunspots

• Solar wind

the nuclear fusion process that converts hydrogen into helium in stars like the Sun and thereby generates their energy. This is the dominant energy-generation mechanism in cool, low-mass stars.

• CNO cycle

• Proton-proton chain

• Thermonuclear fusion

• R-process
