OUR SUN

OUR SUN 4. 01 Solar Nebula: - Cloud of gas and dust that developed into the solar system. - Our Sun was developed as a star from the burning of Hydrogen gas. Nebular Theory - Accepted idea that the sun and the planets condensed out of a spinning cloud of gas and dust.

Core Hydrogen fusion H + H → He + energy

Chromosphere Solar atmosphere Solar storm activity observed

4. 04 Sunspots Cool, dark areas of gas within the photosphere. Caused by powerful magnetic fields. Slows down convection currents to the Photosphere, causing a cooling of certain areas of the surface.

4. 04 Solar Prominence: - Cloud of glowing gases that arches high above sun’s surface.

Granulation 4. 04 caused by the convection, or `bubbling' of the sun.

4. 05 Atomic Structure of Sun’s Core Hydrogen Atoms (H) splitting to Helium (He) Atoms Causes a great amount of energy See 5 step process in book page 572
