THE LAYERS OF THE SUN

• Core, radiative zone, con

THE TEMPUTURES OF THE LAYERS

• Core: 15,000,000° C
• Radiative zone: 2,000,000° C to about 7,000,000° C
• Convective zone: 2,000,000° C
• Photosphere: 5,527 degrees Celsius
• Chromosphere: 6,000 degrees celsius to 50,000 degrees celcius

HOW NUCLEAR FUSION PRODUCES ENERGY

• Two hydrogen nuclei (protons) collide and form deuterium (heavy form of hydrogen)
• Deuterium combines with another hydrogen nucleus to form a variety of helium. of helium-3.
• Two helium-3 nuclei combine to form helium-4 which releases more energy and a pair of hydrogen nuclei

HOW ENERGY IS TRANSPORTED THROUGH THE LAYERS

• By radiation: energy is travels in the form of electromagnetic waves, but they can't travel directly so they have to be absorbed and re-emmited until,they make it to the top of the radiative zone.
• By convection: energy is transferred by the movement of matter until it reaches the photosphere.

HOW THE SUN ROTATES

WHAT IS SOLAR ACTIVITY?

SOLAR FLARES, SUN SPOTS, SOLAR PROMINCES AND CORONAL MASS EJECTIONS

• Sun Spots: dark areas that form on the surface of the sun.
• Solar flares: an explosive release of energy that can extend outward as far as the suns outer atmosphere.
• Solar Prominences: huge loops of relatively cool gas that extend outward from the photosphere thousands of kilometers in the outer atmosphere.
• Coronal mass ejection: coronal gas that is thrown into space from the sun.

WHAT ARE SOME WAYS THAT SOLAR ACTIVITY AFFECTS EARTH?

• Coronal mass ejection particles can fly into space and the parts can hit the Earth.
• Auroras can be shown in the sky because particles of solar wind are attracted to earths poles and can interact with the mesosphere.
