Our Sun

Front

Electromagnetic energy travels in the form of ________

Back

Photons are the particles that carry electromagnetic energy, traveling at the speed of light.

Front

The visual portion of the sun. Only 10,000 degrees

Back

Photosphere is the visible surface of the sun, where light is emitted.

Front

Outermost portion of the sun's atmosphere. Can only be seen during a solar eclipse.

Back

Corona is the outer layer of the sun's atmosphere, visible during a solar eclipse.

Front

Reaction of heavy atomic nuclei splitting into lighter ones producing energy.

Back

Fission is the process where heavy atomic nuclei split into lighter nuclei, releasing energy.

Front

Transfer of Heat. Energy, as photons, that comes from a source and travels through space at the speed of light.

Back

Radiation is the transfer of energy through space in the form of electromagnetic waves.

Front

The center of the sun where nuclear fusion occurs.

Back

Core is the innermost layer of the sun, where temperatures and pressures are extremely high, enabling nuclear fusion.

Front

The layer of the sun where energy is transferred outward by radiation.

Back

Radiative zone is the layer surrounding the core where energy moves outward primarily through radiation.

Front

The layer of the sun where convection currents transport energy to the surface.

Back

Convective zone is the outer layer of the sun's interior where energy is transported by convection.

Front

A large, bright feature extending outward from the sun's surface, often in a loop shape.

Back

Solar prominence is a large, bright feature that extends outward from the sun's surface, often looping back.

Front

The process by which hydrogen nuclei combine to form helium, releasing energy.

Back

Fusion is the process where hydrogen nuclei fuse to form helium, releasing vast amounts of energy.
