“The Sun”. I Life Cycle of the Sun:. A. Stars are born in nebulas. B. Nebula- A rapidly condensing cloud of gas and dust. C. Star “Pre-life Steps”. 1. Gases rapidly condense to star dust. 2. Masses form. 3. Masses collide with others to form larger pieces of “star stuff”.

Slide 1

"The Sun" I Life Cycle of the Sun: A. Stars are conceived in clouds. B. Cloud A quickly consolidating billow of gas and tidy. C. Star "Pre-life Steps" 1. Gasses quickly consolidate to star dust. 2. Masses structure 3. Masses slam into others to frame bigger bits of "star stuff". 4. Gravitational powers increment.

Slide 2

5. This sets off a "snow ball impact" or chain reaction. 6. One huge article gathers the majority of the "star stuff". 7. Thickness increments. 8. Temperature increments. 9. Combination starts to happen. a.) Fusion-The procedure in which two molecules intertwine to frame another substance. b.) In the suns case there were two particles of Hydrogen, which combined to shape Helium. 10. At the point when combination out put gets to be adjusted with the gravity of the extensive article, a star is conceived.

Slide 3

A. Fundamental Sequence-The starting period of life for all stars. II. Life Cycle Steps: 1. Each Star has a principle grouping. 2. The star spends the vast majority of its life in this stage. 3. Combination proceeds for billions of years. 4. At the point when a star's hydrogen starts to run out, the star starts to enter its next stage. B. Red Giant Phase-Beginning phase of death for little & medium size stars. 1. The combination and gravity of a star gets to be lopsided do to hydrogen running out. 2. This makes the star breakdown in on it self.

Slide 4

3. Another round of combination is activated. This time helium whines together. 4. The star swells to a few times its unique size 5. Remaining gas glides path as the star cools. C. White Dwarf-The rest of the center of a little or medium star after the red goliath stage is over. 1. The stars weight amid the red goliath stage will make the star breakdown in on it-self. 2. All that is left of the star now is a caved in center. 3. About the extent of earth. D. Dark Dwarf-The last phase of death of a little or medium size star.

Slide 5

1. After the stars center cools enough that its luminosity is zero a star enters this period of life. 2. All that is left is a modest bundle of "dead material" III. Properties of the Sun: A. Size: 1. More than 99% of all matter in our nearby planetary group is in the sun. 2. Around 110 times the distance across of the earth 3. The sun could hold more than a million earths. 4. The mass of the sun is 745 x more noteworthy than all of the planets set up together.

Slide 6

B. Separation: 1. Earth is 1 AU far from the sun. (93 million miles) IV. Layers of the Sun: 2. Light takes around 8 min. furthermore, 20 sec. to reach earth. C. Temperature: 1. Inside temperatures can be as high as 15 million degrees C. 2. Environment temperatures can be as high as 6,000 degrees C. A. Center: 1. The territory where the sun makes its vitality.

Slide 7

2. Nicknamed the sun's energy plant. 3. Where the greater part of the sun's combination happens. B. Photosphere: 1. To begin with layer of the sun's climate. 2. Regularly called the "sun's surface". 3. Layer of the sun in which light is emitted. C. Chromosphere: 1. The external, less thick, layer of the sun's atmosphere. 2. Red in shading because of cooler temperatures. 3. Sunlight based Flares happen there. a.) Solar Flare-gasses, close sun spots, that shoots outward, at high speeds.

Slide 8

D. Crown: 1. External most layer of the sun. 2. Must be seen amid a sun based overshadowing. 3. Will harm your eyes on the off chance that you take a gander at the sun oriented eclipse without defensive eye product. 4. Sun powered wind happens here. a.) Solar wind-electrical charged particles that escape from the sun's crown. 5. Both the sun oriented wind and sun based flares are responsible for Aurora Borealis. an.) Aurora Borealis-When earth's environment associates with the particles from sun oriented flares and sun oriented wind, delightful shades of light shine in the sky. b.) Sometimes called the Northern Lights.

Slide 9

A. What are sunspots? 1. Sunspots-zones of the photosphere that show up to be dull in light of the fact that they are cooler than the regions around them. V. Sunspots: 2. We discovered that the sun pivots by contemplating sunspots. 3. They can show up and vanish on occasion. 4. A sunspot greatest will occur each 10 to 15 years. 5. A few information propose this may have an impact on earth's climate. 6. No information has ever affirmed that this example impacts anything on earth.
