Presentation of the sun by Shayne Garcia Elisak https://padlet.com/1824210/ao44sdc9voa7 Made by Shayne en-us 2019-02-20 01:35:45 UTC 2019-03-10 21:30:48 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Bigthunderstorm.png Why is the sun important? 1824210 https://padlet.com/1824210/ao44sdc9voa7/wish/333003363 - The sun is very important! If the sun didn't exist, the earth would become a very cold ball of ice.
 
- The sun warms our seas, generates our weather patterns, helps us growing green plants that provide food and gives us energy and heat.

- If the sun went supernova it would be defying the laws of physics (supernova is an explosion)
- the explosion would be equivalent to a few octillion nuclear warheads, an explosion like this would release a lot of energy.
- It would affect the earth's ozone, if the ozone was impacted to cause at least 10 percent increase in ground level UV radiation, it would end all marine life.
- If the sun went supernova the earth would be at least 15 times hotter than the sun and would take a few days to vaporize.]]> 2019-02-20 01:52:58 UTC https://padlet.com/1824210/ao44sdc9voa7/wish/333005969 1824210 https://padlet.com/1824210/ao44sdc9voa7/wish/333009224 2019-02-20 02:07:22 UTC https://padlet.com/1824210/ao44sdc9voa7/wish/333009224 1824210 https://padlet.com/1824210/ao44sdc9voa7/wish/333009671 2019-02-20 02:09:33 UTC https://padlet.com/1824210/ao44sdc9voa7/wish/333009671 1824210 https://padlet.com/1824210/ao44sdc9voa7/wish/333499107 2019-02-21 05:29:18 UTC https://padlet.com/1824210/ao44sdc9voa7/wish/333499107 How nuclear fusion works in the sun: 1824210 https://padlet.com/1824210/ao44sdc9voa7/wish/334378749 2019-02-23 01:42:34 UTC https://padlet.com/1824210/ao44sdc9voa7/wish/334378749 What atoms form the sun? and how do they interact with each other? 1824210 https://padlet.com/1824210/ao44sdc9voa7/wish/334379528 - In the sun's core, a gravitational force creates intense pressure and temperatures.
- The temperature in that layer of the sun is 27 million degrees Fahrenheit.
- Hydrogen atoms are compressed and fused together, forming helium. This is called nuclear fusion.As gas heats up, atoms break apart into charged particles which turn the gas into plasma.
- The energy in form of photons and neutrinos can enter the radiation zone and the photons can bounce around randomly in the zone from a few thousands to around a million years before travelling to the surface.]]> 2019-02-23 01:49:48 UTC https://padlet.com/1824210/ao44sdc9voa7/wish/334379528 What are nuclear bombs? How are they compared to the reactions in the sun? 1824210 https://padlet.com/1824210/ao44sdc9voa7/wish/334384646 - Nuclear bombs are bombs made out of nuclear energy used to create and explosion
- The sun's energy is practically a never ending nuclear explosion, only bigger.
- Fusion causes the massive release of energy; in the sun, hydrogen atoms compress together and release energy creating helium. In the nuclear device, there are two kinds of charges: the primary and the secondary. The primary charge splits atoms to produce energy. The heat and energy from the primary charge causes the secondary charge to explode, which contain materials for fusion. The fusion in the second device causes a much bigger explosion.
- The sun isn’t just a single nuclear explosion, it’s a never ending one.
- The nuclear explosion and the sun are similar in a way that they both release lots of energy, but the sun’s energy is self contained because of the sun’s mass and gravitational pull.
- The energy off the sun can take up to 100,000 years to reach the surface, once it’s in space it only takes 8 minutes to reach the earth’s surface.
