HOW is the H-R Diagram used?

1.) The main sequence of the H-R Diagram represents most of the stars in the diagram.
2.) 90% of the stars in the H-R Diagram are main sequence stars.
3.) The Sun is a main sequence star.
4.) The Sun will next become a red giant.

5.) The H-R diagram is used by the cold stars being on the right, the bright stars on the top, the dim stars on the bottom, and the hot stars on the left.

1.) The top brightest stars are as followed:
- Sun
- Canopus
- Vega
- Procyon
- Rigel
- Betelgeuse
- Capella
- Arcturus
- Sirius
- Rigel Kentaurus
2.) The star I picked is the Sun.
3.) The sun is actually classified as a G2 star on the HR diagram.
4.) Eight planets orbit this star

Which Astronomy topic do you like?

Black holes, Pluto, Andromeda Galaxy, Constellations, and Sagittarius B, and Apollo missions.

Black holes form when a star at least three times bigger than the sun is destroyed and the suction power just pulls you in being called a black hole from which their is no return. They are objects so dense that sense nothing is faster than light, nothing can escape a black hole. They would say that anything with the same mass and same distance away would still get sucked inside the black hole. The mass of a super massive black hole can be measured using radio astronomy.

Pluto is a dwarf planet that is now no longer considered one of our planets. In Greek it means Hades which is the god of the underworld. It was given this name because of its distance from the Sun makes it so dark. Did you know that Pluto was discovered by accident. It is very small and located in the Kuiper Belt. Pluto's radius is unknown and is most likely to be found somewhere in the next five years. Pluto can also reach certain temperatures such as -235 and -210 C.

Andromeda Galaxy has been said that it is possibly brighter than the Milky Way. It is a spiral galaxy and is located northwest of Mu and Beta. The Andromeda Galaxy has a diameter of over 200,000. It also has been suggested that Andromeda holds anywhere from 700 billion to 1.2 trillion Solar-masses. It was found in the 1990s that the Andromeda Galaxy has a nucleus with a double feature

Constellations are groups of stars that form pictures or collections of 88 different star groups. They can even be further divided into eight different families. The Greeks used to assign certain heroes or gods after pictures in the sky. Regions later on around the south pole got their names from the Astronomer Johan Bayer who followed the tradition of names brought from the sea and its creatures.

Apollo Missions contained 17 missions and most of them were somewhat successful. In Apollo mission 1 a fire broke out and killed three U.S. astronauts but in Apollo mission 7 it was the only manned mission launched on a Saturn 1-B rocket from pad 34 at the Kennedy Space Center. In this mission the crew circumnavigated Earth 163 times and spent 10 days and 20 hours. In Apollo mission 10 it was the second one to orbit the moon but the very first one to travel there and receive information about the Moon. Also their was much going on in Apollo mission 11 they returned to earth with the first samples of foreign body masses.

What factors affect wind?

The three factors that affect wind are friction, Coriolis Effect, and pressure differences. I think friction because friction between two plates can cause a subduction zone thus creating a volcanoe. If friction stopped then most likely we wouldn't have as many faults in our Earth's surface.

What are the cloud types?

1. Three low clouds are Cumulus, Stratocumulus, and Stratus. Three middle clouds are Altocumulus, Altostratus, and Nimbostratus. Three high clouds are Cirrocumulus, Cirrostratus, and Cirrus.

2. The clouds that look the best to me are the Cirrostratus because they look like a big, thin, white curl of hair up in the sky. Its look just so interesting and pretty.

3. They don't really consist of precipitation but may warn you of upcoming bad weather.

What's the greenhouse effect

The greenhouse effect is just a bunch of gases that allow direct sunlight to reach Earth's surface unimpeded. So the greenhouse is nothing but he "heating" of Earth. The three most common greenhouses gases are nitrogen which is the most aboundant, oxygen which is the second most, and argon which is the third most abundant greenhous gas. Greenhouse gases are produced when we burn forest land and mining or burning coal. The greenhouse effect has an impact on our lives when it is similar to global warming and the negative results to follow. Other negative results are sea levels rising, severe floods and droughts, and Earth's precipitation

What grade do i deserve?

I would think I deserve at least a C because I haven't been keeping up with my blog posts and really didn't care about them. My spelling and grammar are amazingly good when I pay attention and don't let pety stuff get in the way. I can't argue with you for that is not who I am but hopefully you take this little thing into some consideration.
