My Grade

Hmmm....

I think my grade should be an A. I think so because I completed every blog that was assigned with correct grammar (don't count me on that lol) and hard work. Also, I even have an extra blog or two!

Earth Sciences

Geology

My favorite thing about Geology that i have learned is probably the history of Earth because there is just so much to lean and it is just amazing to me that Earth is just constantly changing in so many ways, its just unbelievable!

Oceanography

Oceanography was also interesting. My favorite thing when I was learning about it was all the different life in the ocean, because the oceans are just so big and there is just so much life and to learn from all those things down there it's just amazing.

Meteorology

When I was studying Meteorology, I thought learning about the structure of our atmosphere was pretty cool. I was actually amazed because i didn't even know our Earth had layers of the atmosphere. I thought it was like just on big bubble of air lol.

Astronomy

Astronomy i would have to say would be my favorite topics. I thought our whole solar system was just so amazing to learn about because there is just a whole lot of things we don't know about and there are so many questions i still have. But bot only our solar system was my favorite but i think that the whole Astronomy unit was my favorite!!!! I enjoyed everything i learned from it.

H-R Diagram

This diagram show the main star sequence. From the left(blue) is the hottest and to the right (red) is the coolest. Off from the sequence there are the Red Giants. Those are just very large, bright, cool stars. There is also the white dwarfs. Those stars are small and normally the towards end of the star's evolution.

1. On an H-R Diagram, what is the main sequence?

The main sequence on an H-R Diagram is the hottest to coldest from left t right.

2. What percentage of stars are main sequence stars?

90%

3. Is the Sun a main sequence star?

Yes

4. What will happen to the Sun next? When will this happen?

Evidence shows that the Sun will grow dramatically and engulf the Earth before it dies out.

Achernar

1. Name 10 stars.

Sirius, Canopus, Alpha Centauri, Arcturus, Vega, Capella, Rygel, Procyon, Achernar, and Betelgeuse.

2. Choose one star. Which one did you choose?

Achernar

3. What kind of star is it?

Achernar is a Class B star, and will eventually evolve into a White Dwarf Cloud.

4. Are there any planets that orbit this star? Tell me about them.

This star has no planets.

5. What galaxy is this star a part of?

The Milky Way

6. How far is the star from Earth?

We are in the milky way, so Achernar is not that far away!

Here is my Chapter 22 Webquest!

Astronomy Topics

Black Holes
Black holes are theoretically predicted pockets in space where neither light nor matter can escape. They are the end of stars and at least 10 to 15 times the size of the sun! But black holes are highly exaggerated by the public. They are not super vacuums, so if our sun was to be "swallowed" by one our orbit would not change. Only out temperature.

Saturn's Rings
Saturn's rings were discovered by Galileo in 1610, but they would always puzzle scientists. They figured that the rings were mainly made out of ice water and range from microns to meters in size. The rings are there because of Saturn's gravitational pull. As also the moons, but much of it remains unexplained.


The Ultimate Fate of the Universe
We can't predict the future. But we can give a hypothesis on what might happen, and that's just what scientists are doing. They say that years from now the universe is just getting farther and further away from everything else and just finally one day, crush together in a pin size ball, just like how it started. The big bang.

Pluto
Pluto gets its name from the Greek god of the underworld, Hades because, how far it is away from everything. It was discovered in 1930 just by a fortunate accident. Then again in 2005, Pluto was discovered to have two smaller moons orbiting it. But now sadly Pluto is no longer considered a planet. :[

Worm Holes
Wormholes are not yet proved yet but not disproved either. They are said to be teleporters in space over time! This theory goes back to 1916, shortly after Einstein published is theory in books. Although wormholes are probably unstable and would collapse if any of the tiniest matter would enter it so.....if they are discovered I wouldn't try this at home.

Wind Factors

1. What 3 factors effect wind?

The 3 factors that effect wind are pressure, the Coriolis Effect, and friction.

2. Whcih of the 3 do you think has the greatest effect? Why?

I thin pressure has the greatest effect.

3. What would happen if this factor (from #2) all of a sudden stopped? Remember to include details about what might happen in your response.

If this was not here anymore than there would be no wind force.
