When we look up into the sky, what do we see? During the day, we often will find the sun. The sun is much more than a ball of fire that we see in our daily lives. The sun gives earth life, from the condition of the season of the life that is produced. Overall, when we think of the sun we think of heat and light, but one might question; how does the sun produce the heat and light that is necessary for the earth to sustain life? The sun is also known as a star, just like the stars we see at night that illuminate the night sky. Stars are categorized by the Stellar Classification system, which accounts for spectra appearances from the light of a star. According to the chart, the sun is considered a G2 V, the G class of stars have a temperature between “5200 to 6000 K and have a weaker hydrogen line and neutral metals,” (“Stellar Classification,” 2014). A common name for the sun is the dwarf star, and “the V classification indicates that the sun is a main-line sequence star and generates energy by nuclear fusion,” (“Sun,” 2014). Similar to the Earth’s structure, the sun is made up of an inner core and atmosphere, having an understanding of the structure of the sun will help in understanding how heat and light are produced.
The innermost lay of the sun is known as “the core.” The core of the sun helps to begin the generation of heat and light, which feeds the Earth’s life. The inner most portion of the sun has the highest temperature and the most pressure. Based upon the category of the sun in the stellar classification, it is made up of hydrogen and generates energy from nuclear fusion. Nuclear fusion reaction is “when two or smaller light nuclei combine to form a larger nucleus,” (Young, 2012). The hydrogen atoms perform nuclear fusio...

In “The Warmth of Other Suns” by Isabel Wilkerson, the three main characters that the story follows face a great deal of inequality and racial prejudice in both the Jim Crow south that they left and the north that they fled to. Through their stories, as well as the excerpts from Wilkerson that serve to dispel some of the common myths and to explain some of the inequalities that others faced, one is able to make many connections between the problems that Ida Mae, George Starling, and Richard Foster, among many others, faced in their time and the obstacles to equality that our society still to this day struggles to overcome. A large reason as to why these obstacles still exist is that many have preconceived ideas about African Americans and African American Communities. However, numerous obstacles still survive to this day as a result of certain racist ideas.

The sensitive instruments aboard the SOHO spacecraft have already helped scientists here on Earth discover and explain some of the mysteries of the Sun as well as to confirm some of their theories they previously held. For example, in May of 1998 with the help of the Michelson Doppler Interferometer scientists were able to see with greater clarity the giant convective cells inside and on the surface of the Sun.
Stars are born and reborn from an explosion of a previous star. The particles and helium are brought together the same way the last star was born. Throughout the life of a star, it manages to avoid collapsing. The gravitational pull from the core of the star has to equal the gravitational pull of the gasses, which form a type of orbit. When this equality is broken, the star can go into several different stages. Some stars that are at least thirty times larger than our sun can form black holes and other kinds of stars.

absorb the energy from the sun, but it does absorb some of the heat energy
Our Sun continuously converts hydrogen into helium and with this process it provides the essentials for life processes. In doing this it controls “our climate, provides light, raises tides, and drives the food chain” (Schaefer 34). Our Sun also has influenced many beliefs now and in the past. History has documented Sun worshipping religions while many current societies use solar calendars (Schaefer 34).
Light is a very important factor in the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise. It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch .
Our sun is the central pivot point to which or entire planet and solar system is built around. With out it all life on our planet would cease to exist. Within this paper we will explore how our Sun and solar system formed and came to resemble what we see today.
The commonly debated “greenhouse effect” refers to “the global average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue in an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere. As an outcome, researchers around the globe have established that the by-product of burning fossil fuels is the main culprit of the increasing temperatures. Global carbon emissions from fossil fuels have significantly increased since 1900, as shown above from a study carried out by the Carbon Dioxide Information Analysis Center.
The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...

... You can think of solar winds as the external corona in an episode of continuous expansion. The solar wind is made of pretty much the same material as the lower corona or photosphere of the sun. Solar winds usually have lots of Hydrogen because Hydrogen tends to be attracted to solar winds. This is much unlike Helium because Helium is not attracted to solar winds. The sun loses little bits of energy because solar winds take atom parts (protons, and electrons) from it. Solar winds take over 1,000,000 tons worth of mass from the sun every second, but our sun’s mass is so much that this much mass is considered pretty much nothing. The sun’s heliosphere is taken over by solar winds. The solar winds have less and less pressure as it gets farther and farther from the sun. At 100 AU from the sun the solar winds cannot balance on their own because it is interstellar space.
