Science is very hard to understand sometimes and this book is going to help you understand science!!!!
What is science?
Science is all around us we walk through it we breathe it we even use it.So what is science? science is the formations of all living things like bacteria and pathogens . Science is what defines us and the world around us. What can science give us? Science can give us a lot of things from tools we use to things we learn!
Our sun is the source to all living things on earth. In fact without the sun the earth wouldn't even be formed. the suns gravity in its core pulls in gravity and puts out gravity as well as the elements in the surface of the sun such as co2 and nitrogen. When the core runs out of energy it can no longer sustain the energy required to keep its self in place. The sun then collapses on its self and explodes into the next stage witch is a red giant. Once the star is in its next stage it regains the core and does the same thing. It pulls gravity in and pushes it out to sustain gravity and pull. Once the core finally finalizes it then collapses again either into a blackhole,white dwarf,or a nebula witch actually creates more stars. When a blackhole is formed it can also go 2 ways. It can become a galaxy or stay a constant black hole are sun will just stay a blackhole if it goes that path. When something becomes a blackhole it has a quasar and explodes 2 beams of light destroying everything in its path. A white dwarf is the final stage of the sun.
The atmosphere is a protective coating that blankets the earth. The atmosphere is made up of 5 layers gases and particulates. The five layers in order from bottom to top are the Troposphere the Stratosphere the Mesosphere the Thermosphere and the Exosphere. The hottest layer is not the troposphere but rather than the thermosphere. The harmful radiation from the sun are trapped inside of the ozone layer or o3. The uv light trapped in the o3 in the thermosphere and mesosphere heat up the molecules to about 2,000 degrees celcius. But because the air is so thin it spreads the molecules making the atmosphere feel cold. The pollution destroys the ozone layer and puts o3 inside of the troposphere witch is dangerous because o3 is toxic to breathe. The atmosphere is composed of 76% nitrogen 17%oxygen 4%water vapor 2% co2 or carbon dioxide and 0.03%argon. leaving 0.07% particulates such as dust water droplets etc. This is the composition of earths atmosphere.
