1. I learned about Muscovite in Journey to the Center of the Earth. It is super thin rock that breaks easily. I also learned that magnesium is very flammable and that humans can't survive in over 130 degrees Fahrenheit

2. Three things that were scientifically untrue were that dinosaurs are completely extinct, there isn't another world at the center of the Earth, and I'm pretty sure there is no such thing as a glowing bird.

1. My favorite topic we learned about this year in earth science was astronomy.




2. In this topic I learned about space and the planets. I learned about the terrestrial planets and Jovian planets. The terrestrial planets are Mercury, Venus, Earth, and Mars. The Jovian planets are Jupiter, Uranus, Saturn, Neptune, and Pluto. I also learned about black holes. (which was my topic to research and explain to the class) This was interesting to me because I learned a lot about black holes i did not know before. For example, I learned that the reason black holes have so much gravity is because it is smaller, not because it was more massive. I also learned that the only way for a star to become a black hole is if it is 3 times larger than our sun. (So our sun may never become a black hole.) Astronomy was a very interesting topic to learn about. (:

3. I found it interesting because I learned about stuff I had never even thought about before. I got to understand how the universe works. It was also interesting because Mr. Dunn made it fun! Unlike other teachers in the past (:

I think that before the "big bang" happened there was nothing in our universe. Before it happened it was too cold for any stars or planets to form.
One theory as to what cause the big bang is the m-theory. This suggests that two other universes collided causing another universe to form (ours). So now, they believe there is a multiverse (more than one universe.)

1. Astronomers can detect extra-solar planets by radial velocity, astrometry, transit method, and optical detection.

2. Astronomers detect extra solar planets by radial velocity which is also known as the Doppler spectroscopy. This is when they detect the movement of a star which is caused by the gravitational pull of another planet. They use the Doppler effect to detect the frequency of waves that are coming to or away from us. When it is moving away, the light of the spectrum is red, and vise-versa it is blue. They then can determine the size and orbit of the planet.

3. About 75 planets have been discovered by radial velocity.

My favorite planet is Earth. This is because with out Earth I wouldn't be alive today. It is my home and has beautiful landforms. I also think that Earth looks the prettiest from space. (: Earth provides me with the air I need to breathe, the water I need to drink, and the food I need to eat.

Black Holes: Black holes form from a red star that collapses on itself. They are 10 to 15 times more massive than the sun. Its gravitational pull is so great that even light cannot escape. For something to get sucked into one it has to pass the Schwarzschild radius. Once it passes this point, you cannot escape.

Mars: Mars is the 4th planet from the sun. Its atmosphere consists of mostly carbon dioxide. It has two moons named Diemos and Phobos. At a certain time of year Mars seems to exhibit retrograde motion from Earth's point of view. At one point people thought there might be a possibility that humans could live on mars but it gets to outrageous temperatures.

Pluto: It is debatable if pluto is a planet or not. It actually is classified as a dwarf planet which means it has not cleared it's orbit. Pluto is small and rocky and comes just after Neptune. It is so cold on Pluto that nitrogen and oxygen becomes frozen. It is two-thirds the size of our moon, but is the largest object in the Kuiper Belt.

Asteriod Belt: The asteriod belt comes right after Mars but right before Jupiter. THe asteriod belt consists or, yes, asteriods! Asteriods are chunks of rocks, that sometimes can be metals. Every now and then an asteriod come into Earth's atmosphere and strikes Earth's surface. Some don't even reach the surface, they can burn up because of how fast they come towards Earth.

Milky Way Galaxy: The milky way galaxy consists of Mercury, Venus, Earth, Mars, Asteriod Belt, Jupiter, Saturn, Uranus, Neptune, Pluto, then the Oot Cloud. We, obviously, live in the milky way galaxy. It is about 13 billion years old.

I do believe that Pluto is really a planet. It revolves around the Sun and it is spherical just like all planets. Pluto is not just a block of ice, it even has more than one moons that revolveround it.

Blog post #7

1. A monsoon is a seasonal wind shift.
2. The two major factors that cause monsoons are the Bermuda High and the thermal low.
3. Monsoons can be considered a good thing because it brings thunderstorms to usually dry places, such as Arizona, and it helps the farmers out there because their soil will become more fertile from the water.
4. Two negative effects of a monsoon is that it can cause flash floods and severe thunderstorms.
5. So many people died because there was harsh raining after a severe dought that caused lots of flooding.
6. Monsoon are both good and bad. They bring rain to very dry places but that rain can destroy towns. Monsoons cause lots of deaths, but they can water crops for farmers.

Global Warming

1. "Global warming is an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution." http://www.google.com/search?hl=en&safe=active&defl=en&q=define:global+warming&ei=tcPpSrDTM4-Vtgeshek6&sa=X&oi=glossary_definition&ct=title&ved=0CBYQkAE

2. I don't have strong views about global warming. I am pretty much neutral when it comes to this. Both sides of the argument make valid points.

3. Global warming is worldwide temperature increase, and the past two decades have been the hottest in 400 years. People also make the point that the arctic ice is melting, and there is more carbon dioxide in the air.

4. Scientist Timothy Ball has a Ph D. in climatology and states facts as to why global warming does not exist. First of all he says the global warming is not due to human contribution of Carbon Dioxide. Secondly, he says that this has happened before, but Eath's climate then began to cool again. It is only a cycle that will happen continuously.

Condensation

1. Frozen water bottle with water on the outside.
-Condensation Nuclei = the water bottle.
2.Covered pot on the stove, when you take off the cover, the water droplets.
- Condensation Nuclei = the pot cover.
3.Glasses fogging up because it is cold outside.
- Condensation Nuclei = the glasses lenses.
4. Steam room
- Condensation Nuclei = The glass door in the steam room.
5. Dishes in the washing machine waiting to be dried.
- Condensation Nuclei = The dishes.

Hurricane Iris

1. I chose hurricane Iris (2001)

2. On the Saffir-Simposon scale it was a category 4.

3. On October 5th it was named as a tropical storm, but by the 6th it became hurricane Iris. It passed Jamaica on the 7th and went westsouthwestward towards the coast of Bezile. It was responsible for 31 deaths.

4. 31 lives were lost. Didn't metion how much money.

Blog Post #3

1. The 4 types of air-masses are : Maritime Tropical (mT) - Wet and Warm
Maritime Polar (mP) - Wet and Cold
Continental Tropical (cT) - Dry and War
Continental Polar (cP) - Dry and Cold

2. Maritime Tropical would more likely bring a hurricane.

3. Continental Tropical because it is dry and warm.

4. The arctic air mass brings lake-effect snowstorms.

5. The two other air masses are arctic and highland. A highland air mass is in regions with large elevation changes over short distances. An arctic air mass has the same characteristics of polar, except it is much colder.

Greenhouse effect

2. IR radiation is when the Earth's surface absorbs the solar energy and releases it back into the atmospher as IR, or heat.

2. The three main greenhouse gases are carbon dioxide, methane, and water.

3. I think that the greenhouse effect is a bad thing, because it contributes to what we know as global warming.

RECYCLING !

1. We should recycle glass because every ton of glass recycled saves 9 gallons of fuel oil needed to make glass. It also helps to save the environment.

2. I think recycling and reusing things are equally important. When you recycle is ends up getting reused in one way or another, and instead of throwing things out that can be reused again, you can reuse them which can reduce the amount of trash in landfills.

3. Fayetteville residents can recycle by using a blue trash can with their recyclables. They can set it at their curb on their weekly pick-up day and 7 am.

4. The closest recycling center to my home is on N Bragg Blvd.

5. Recycled plastic can be made into bottles, shower stalls, recycling bins, souring pads, paint brushes, industrial strapping, drainpipes, plastic lumber, and flowerpots.

6. Recycled metal can be made into cans, car parts, siding, appliances, and building materials.

7. To promote recycling I can inform people I know the benefits of recycling and try to encourage them to do so. I could also post posters around my school to aware people the dangers of not recycling.

My Grade

I believe that I deserve an A on my blogs this quarter. Just like last quarter all of my blog posts meet their criteria. There are also no spelling mistakes in any of them. The ones that needed pictures I provided one. I also provided pictures for the blog posts that did not require one. The difference from my blog post than (mean) Miranda's blog post is that instead of saying I should do better than her, I believe that we will BOTH get good grades. See I am a very nice person.(worthy of extra credit!) Just kidding! But yes, I do think I deserve an A. (:

The Pacific Ocean

I chose the Pacific ocean. Natural resources that come from that ocean include:

Fish

Pearls

Oil

Gas

Polymatallic Nodules

Geologic

1. The geologic periods in order from oldest to youngest are: the Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, Permian, Triassic, Jurassic, Cretaceous, Tertiary, and Quaternary.

2. C.O.S.D.M.P.P.T.J.C.T.Q
Cause Owen sometimes drinks mustard, people play tricks just cause they quite.

(Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, Triassic, Jurassic, Cretaceous, Tertiary, and Quaternary.)

Tree Rings

1. Scientists can tell the age of a tree by looking at the rings because each ring represents one year.

2. This is useful because you can tell how long a tree has been around, as well as how long earth has been formed.

3. This is an example of absolute dating, because if you counted each individual ring you would get the exact age that the tree is.

Unconformities

The order the picture goes in is from D, A, E, B, C. (oldest to youngest rock layers)

I know E comes before B because it does not go through B, showing it formed before B. I also know that C came after B because it goes through all of the layers all the way up to the surface.

Earthquakes VS. Volcanoes.

I personally think that earthquakes are more dangerous than volcanoes. This being because there are more earth quakes happening every day than volcanoes erupting. If you knew there was an active volcano anywhere, you would not build a house or anything near it. But, you can never be sure were an earthquake will happen. On May 27, 2006 there was an earthquake in Indonesia with a magnitude of 6.2 that killed more than 3,000 people and injured thousands. That is a lot of people dead from just one earthquake.

The Center Of The Earth

1. The deepest mine in the world is 3.6 kilometers deep.

2. You would have to dig 35 km to reach the mantle.

3. If I was able to reach the mantle it would look like molten rock (magma). It would probably be like being in an active volcano. The inner core would be liquid iron, and the inner core would be extremely difficult to get through because it would be solid iron. By the time i reached the surface on the other side, the molten rock (magma) would probably follow me up.

My Grade

I think I deserve an A on my blog posts because they meet the criteria. The first four blog posts required a picture and I provided one. They also have paragraphs for each of my responses. There is no spelling mistakes, and I completed them on time. I believe that is deserving of an A Mr. Dunn. Thank you. (:

Rocks

1. The two types of igneous rock are extrusive and intrusive. .Extrusive igneous rocks form when lava hardens above Earth's surface and intrusive forms when magma hardens below Earth's surface .An example of intrusive is gabbro and extrusive is basalt.

2. The two types of metamorphic rock are foliated and non-foliated. Foliated rocks, such as gneiss have a layered or banded appearance which is produced by heat and direct pressure. Non-foliated rocks, such as marble, do not have a layered appearance.

3. The two type of sedimentary rock are clastic and chemical. Clastic sedimentary rocks, such as breccia, form from mechanical weathering. Chemical sedimentary rocks, such as rock salt, form when dissolved materials precipitate from solution.

Cars

If my parents had to buy a new 2009 or 2010 model car I would recommend the Saab
Convertible. This is because, first off, it is not too expensive for a new car. Also, its milage isn't too bad, it's actually pretty good. Another reason, is who wouldn't want a car where the hood could go down? I mean I would.

Minerals.

Sulfur - I eat eggs.

Gold - My jewelry.

Halite - I use salt on my food.

Copper - I have pennies.

Silver - Some of my jewelry is silver.

Robinson

My favorite map projection is the Robinson. This is because to me, it is the easiest to read. Also it doesn't just show small areas,(which could be helpful in some cases) but it allows me to see the whole world. The Robinson is the most commonly used map projection, which probably means that it could be used on more than one occasion.

Oceanography

The type of science that sounds most interesting to me is oceanography. This is because, first off, I love the beach. Also I think that knowing and exploring what is in the ocean would be a really cool experience. There are so many creatures in the ocean, and to study them would be incredible.
