Term | Definition |
---|---|
Nuclear fusion: | The process by which nuclei of the small atoms combine to form a new,more massive nuclei;the process releases energy. |
Sunspot: | A dark area of the photo-sphere of the sun that is cooler than the surrounding area`s and that has a strong magnetic field. |
Solar Flare: | An explosive release of energy that comes from the sun and that is associated with magnetic disturbances on the suns surface. |
Prominence: | A loop of relativity cool,incandescent gas that extends above the photo-sphere and above the sun`s edge as seen from earth. |
Core: | The central part of earth below the mantle. |
Radiative Zone: | The radiative zone is the layer of the sun through which energy is transferred away from the core by radiation. |
Convection Zone: | The convective zone layer of the sun through which energy travels by convection from the radiative zone to the photosphere. |
Photosphere: | the photosphere is the visible surface of the sun.It is the layer from which energy escapes into space.The photosphere has an average temprature of 5,527 degrees celsius. |
Chromosphere: | The chromosome is the middle layer of the sun`s atmosphere.Temperature`s increase outward and reach a maximum of about 6,000 degrees celsius. |
Corona: | The corona is the outer atmosphere of the sun.Temperature in the corona may reach 2,000,000 degrees Celsius. |
