__**Think about It**__
 * Solar radiation is helpful to me because solar energy can help fuel buildings, and some vehicles. Solar radiation helps the plants grow which in turn feeds me. Animals can feed on the planets which feeds other organisms
 * Solar radiation can cause cancer and other skin diseases. The UV rays are also to harmful to human skin. -Shayam Patel

__**Check your Understanding**__ E 55 Solar flares interfere with communications and power systems by the scattering of protons and electrons at 800 km/hr in all directions, it causes. This discharge can disturb the upper levels of the atmosphere, which will interfere with radio signals. Also, many protons and electrons traveling at that speed can easily harm satellites in space. Already, two satellites have crashed down due to solar flares throughout history. - Josh Branker

2 column notes activity 5: The sun has 3 layers. These layers are the convection zone, the radiative zone, and the core. The energy of the sun travels out from the core, through a radiative layer and a convection zone above that. Finally, it reaches the outer layers. The Protosphere is the visible surface of the sun, which is seen from Earth. -Alyssa Walker

- **David Meneses** __**Digging Deeper**__ __**Energy Scattering and Reflection:**__ __**2 column Notes:**__ From the Earths surface the sun appears as a white glowing ball of light. Like the earth, the sun has a layerd structure. -//Allyson Fancher//
 * __2 Column Notes – DD Activity 5: Sun and its Effects (pg E50-E55)__**
 * Main Idea**- Solar Flares and Sunspots, sunspots and solar flares happen in the sun.
 * Evidence, details**- Sunspots are small dark areas on the sun’s visible surface. A solar flare is an enormous blast of energy from the sun. These are bad for Earths astronauts and satellites. It also can affect Earth. In 1989 a major solar flare created electric current that made electric things go out.
 * Main Idea:** The structure of the sun (3 parts) Convection zone, radiative zone, and cone.
 * Details:**The convection and radiation zone are zones that energy travels through from the core. The cone is the central region of the sun which is where nuclear fusion occurs.
 * Main Idea-** The earth energy budget is the amount of energy received by Earth and then released back into space
 * Evidence-** Earth's energy can effect the light, climate, and temperature given off on Earth - //Andrew Morris//
 * Main Idea:** The structure of the sun
 * Details:** The core is where the nuclear fusion occurs. It is the source of all energy. That energy travles out through the core, through a radiactive layer and a convection zone above that. Finally it reaches the outer layers: the photosphere, chromosphere and corona.

-The albedo is the reflective property of a non-luminous object, in this case the Earth. __//**Solar Radiation:**//__ solar radiation gives energy indirectly and directly. It gives energy for civilization by wind and solar power by fossil fuels. ultraviolet radiation is not harmful because it causes skin damage and the light comes through the ozone layer. There is some protection from the ultraviolet light such as limit in the sun, staying shade, staying hydrated, and wearing sun block. **-Amani**
 * Main Idea:** How does the albedo of the Earth change how much energy is absorbed or reflected?
 * Details:** A perfect mirror has 100% albedo, while a black hole has an albedo of 0% __//**- Kira Turner**//__


 * __Sunspots and Solar Flares:__**
 * Main Idea- Sunspots are small dark areas on the Sun's visible surface. They can be as small as the Earth or as large as Uranus or Neptune.**
 * Evidence- Sunspots last for a few hours to a few months. They appear to move across the surface of the Sun over a period of days.**

__**4. You have read that Earth's albedo is about 0.30.**__ __4a. In your own words, describe what this means.__ //This means that thirty percent of the light is reflected. Most of this thirty percent is due to high reflectivity of clouds, although the air itself scatters about six percent and the Earth's surface reflects another four percent// __B. Is the Earth's albedo constant? Why or why not?__ //The Earth's albedo is not constant because the albedo of particular surfaces on Earth varies. Thick clouds have albedo of about .08, and freshly fallen snow has an even bigger albedo.//

__**pg E 55 Check your understanding # 2**__ 2. IN your own wordallens explain what is meant by the term solar wind. How does the sun contribute to space weather? -Solar wind is the particles and waves given off by the sun when solar flares occur. The sun contributes to space weather because it gives off heat and radiation.- **Angelo Nuni** The amount of energy received by the Earth and delivered back into space is the Earth's energy budget. The energy budget for a given location changes from day to day and from season to season. The energy resides in various kinds of places, and moves from place to place in various ways and by various amounts. -Alianna Lewis

Reflecting on the chapter challenge

In this activity I learned about solar flares and sun spots, I made graphs based off of the number of sunspots in a given year between 1899 to 1998. I also made a histogram on the strongest solar flares from the years 1978 to 2001.The number of sunspots varies from year to year in a regular cycle and strong solar flares occur in great numbers during high sunspot years. -Kayleah Beltran

Auroras are mostly seen by people that live in northern areas more often than those who live near the equator. -Antoneta
 * __Geo Words__**
 * photosphere**- is the visible surface of the Sun lying just above the uppermost layer of the Sun's interior.
 * chromosphere**- a layer in the Sun's atmosphere, the transition between the outermost layer of the Sun's atmosphere
 * corona**- the outermost atmosphere of the Sun. millions of kilometer in extent.
 * plasma**- a state of matter wherein all atoms are ionized; a mixture of free electrons and free atomic nuclei
 * aurora**- the charged particles from the solar wind end up in an oval-shaed area around the Earth's magnetic polescaused by charged particles enetering the upper atmosphere resulting i a beautiful aurora.

There are three main parts of the sun. The inner most part or center is the core, where all the source of energy is. Next ring is the radiative zone, and the outermost ring is the connective zone. -//Andrej Gavric// Geo Words: 1.) Albedo – the reflective property of a surface 2.) Plasma – The Movement of charged particles 3.) Aurora - a bright display of atoms caused by charged particles leaving and entering the upper atmosphere 4.) Ionosphere - is formed when solar radiation hit the electrons out of the upper atmosphere - Brandy Gibson

Information on Solar Flares: Solar flares intesify the solar wind, which makes the ionosphere thicken and strengthen. When this happens, radio signals from earthe aare trapped inside the ionosphere. This causes a lot of interference. As discussed above, solar activity can also be a problem for satellite operations. -Tyler Rogers
