Which of the following is the most abundant element in the Sun?
Hydrogen
Helium
Carbon
Oxygen
Which of the following is the apparent change in the position of an object due to a change in position of an observer?

When comparing sunspots to the other areas of the Sun’s surface, one can say that sunspots are:
tiny nuclear explosions.
lighter in color.
higher in altitude.
cooler in temperature.
What is the interior or center part of the Sun called?
the radiative zone
the core
the convective zone
the photosphere
The Sun creates energy through a series of steps known as:
electron-neutron chain reaction.
proton-proton chain reaction.
nuclear fission.
proton-electron chain reaction.
This region of the Sun is located near the radiative zone and extends down over 124,000 miles (200,000 kms) from the surface. Once hot materials travel from the radiative zone to the photosphere and cool, they drop back into the base of this region. What region is being described here?
the chromosphere
the corona
the core
the convective zone
