Like the Earth, the Sun has a solid surface.

• True

• False

The Sun has no atmosphere.

• True

• False

Which is NOT a layer of the Sun?

• The Core

• The Radiation Zone

• The Convection Zone

• The Conduction Zone

Where Hydrogen atoms join to form Helium (and in the process release huge amounts of energy).

• The Core

• The Convection Zone

• The Radiation Zone

• None of the answers listed in this question

A layer in the Sun of very tightly packed gas where energy moves mainly in the form of electromagnetic radiation.

• The Core

• The Convection Zone

• The Radiation Zone

• None of the answers listed in this question

An area in the Sun where cooler gases sink, forming loops of gas that move energy toward the Sun's surface.

• The Core

• The Convection Zone

• The Radiation Zone

• None of the answers listed in this question

The process in which Hydrogen atoms are joined together producing Helium.

• Nuclear Fission

• Nuclear Fusion

• Nuclear Alchemy

• Nuclear Protonic Reversal

About 3/4's of the Sun's Mass is comprised of Helium.

• True

• False

The Radiation Zone of the Sun is so dense, some scientists estimate that energy can take more than _________________ years to move through it.

• 1,000

• 10,000

• 100,000

• 1,000,000

In what order does energy move through the Sun"

• Core to Radiation Zone to Convection Zone

• Core to Convection Zone to Radiation Zone

• Convection Zone to Radiation Zone to Core

• Radiation Zone to Convection Zone to Core

• Radiation Zone to Core to Convection Zone
