1. What was your favorite topic that we learned about this year in Earth Science?
My favorite topic that i learned about is the astronomy.
2. Explain this topic. Provide a picture and/or website link to better illustrate what you learned.
Astronomy is about space and whats in it. Like the stars, planets, moons, galaxies, and the black holes.
3. Why is this so cool? Mr. Dunn likes a lot of stuff that we do (that's why we do it). Why did you like this particular topic?
This is cool because it is cool knowing there is a lot of stuff that we need to k now about .I like this topic, because i love to look up at the stars and knowing what else is up there

1. What are the four ways astronomers can detect extrasolar planets?
Radial Velcoity, Astrometry, Opitcal Detection, and Transit Method
2. Choose one of the four ways and explain it in detail.
Radial Velcoity is also known as Doppler spectroscopy, this method measures slight position of a star that happen as it is tugged to and fro by a planets gravitational pull
3. In your answer to #2 you chose one way that astronomers detect extrasolar planets. Search the Internet to find how many extrasolar planets have been detected using this method.
They have not given a answer but a vast amount

Which planet or moon is your favorite? Why? Please include a picture.

My favorite planet is one of saturn's moon, Titan. I like Titan because its the secong largest moon in the solar system, and because its the only one out of three that have an atmosphere.

Black holes emit x-ray radiation and get smaller and smaller until they disappear, or "evaporate". Most black holes form from the death of a large star that are much larger than the sun, that run out of fuel and cannot sustain its nuclear reaction. The gravity around the "hole" of a black hole is so strong that NOTHING can make its way back out after a critical distance. Even before crossing the event horizon, though possible to travel away from the black hole, it is not easy. But even light has a hard time getting out, so light being emitted from something almost at the Event Horizon but not yet inside the threshold takes a much longer time to escape and be seen by someone then it would in normal space going at 186,000 miles per second.
Titan (one of Saturn's moons) was discovered on march 25, 1655, by a man named Christiaan Huygens. Titan is the largest moon of Saturn, and the only one to have a dense atmosphere, and the only moon that has clear evidence of stable water systems. Titan is the twentieth-most distant moon of Saturn and sixth-farthest among those large enough to assume a spheroid shape. The moon is primarily made of water ice and rocky material. Titans atmosphere is largely composed of nitrogen and its climate includes methane and ethane clouds.
Big Bang Theory is an effort to explain how the beginning of the universe was created. According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. What is a "singularity" and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of "black holes." Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called "singularities." Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity.
Milky Way Galaxy is the galaxy which is the home of our Solar System together with at least 200 billion other stars (more recent estimates have given numbers around 400 billion) and their planets, and thousands of clusters and nebulae, including at least almost all objects of Messier's catalog which are not galaxies on their own (one might consider two globular clusters as possible exceptions, as probably they are just being, or have recently been, incorporated or imported into our Galaxy from dwarf galaxies which are currently in close encounters with the Milky Way: M54 from SegDEG, and possibly M79 from the Canis Major Dwarf). See our Messier Objects in the Milky Way page, where details are given for each object to which part of our Galaxy it is related. All the objects in the Milky Way Galaxy orbit their common center of mass, called the Galactic Center
Binary Star Systems
are quite common. In fact, most stars are in binary or multiple star systems. If the orbital plane of a binary star is seen by us nearly edge-on, the stars will alternately eclipse each other. These binary stars are so far away from us that they look like single stars in photographs, but their brightness varies in a particular way due to the eclipses - these are known as eclipsing binary stars. About 6,000 stars of this type are known in our Galaxy and other nearby galaxies.

1. What is a monsoon?
A monsoon is seasonal reverse of wind
2. What 2 major factors cause monsoons?
2 major factors are the movement northward from winter to summer of the huge upper level subtropical high pressure system, and the intense heating of the Mohave Desert creates rising air and surface low pressure
3. Give 2 reasons why monsoons could be considered a good thing.
1 reason is they does not produce thunderstorms every day during the months of July-September, and the other is that this cycle of "bursts" and "breaks" will continue from the onset of the monsoon circulation, which returns our winds to a westerly or northwesterly direction.
4. Give 2 negatives of monsoons.
2 negatives would be severe summer thunderstroms, and flash floods.
5. Why did so many people die here? What exactly happened? Please be complete :)
People diedbecause of flash floods cuased droughts.Sudden rains, coming after a severe drought, deluged villages and caused widespread disruption in the states of Andhra Pradesh and Karnataka.
6. After everything that you have read about monsoons, what do you think? Are they good or bad? Why?
I think that monsoons can be rewarding and very dangerous. They are mostly dangerous, because they cause severe thunderstroms and floods.

1. What is global warming?
global warming is the changing the long-term weather,due to people's ignorance
2. Do you believe in global warming? Briefly explain.
I do believe in global warming, because there is proof that the glaciers are melting,and the temperature is going crazy, due to the carbon footprint.
3. Give three pieces of evidence to support your position on number 2.
The U.S. is responsible for 25% of the carbon dioxide produce in the world.If carbon dioxide emissions are stopped today, we will still feel the effects for years to come. Almost 279 species of plants and animals are already reacting to global warming, migrating north to escape rising temperatures.
4. Despite your response to #2, there are smart people out there that believe the complete opposite of what you believe. Give three pieces of evidence for someone with the opposing viewpoint.
People believe that the climate computers are crude to predict future climates.ICPP dont provethat people are the causes for globel warming.The amount of global warming, would be beneifical to natural worold and to human civilizations.

1. Which hurricane did you choose?
Hurricane Opal 1995
2. What category was it on the Saffir-Simpson scale?
its a category 3 hurricane when it made landfall near Pensacola Beach
3. Tell its story.
Opal was first detected as a tropical wave moving off the African coast on September 11.The combined system then developed into a tropical depression near the east coast of the Yucatan Peninsula on September 27. The depression drifted slowly northward, becoming Tropical Storm Opal as it reached the north coast of Yucatan on the 30th. Opal then moved slowly westward into the Bay of Campeche, where it became a hurricane on October 2.
4. How many lives were lost? How much damage did it cause ($)?
Opal was responsible for 9 deaths in the United States, including 8 from falling trees and one from a tornado. Opal was responsible for 50 deaths in Mexico and Guatemala due to flooding caused by heavy rains.The surge was responsible for the bulk of the $3 billion in damage attributed to Opal in the United States.

1. What are the 4 main types of air masses? What does each letter stand for?
Maritime tropical-mT, Maritime polar-mP
Continental tropical-cT, and Continental polar-cP
2. Which kind of air mass is most likely to bring hurricanes? Why?
Maritime tropical,because hurricanes need the necessary heat and moisture to the air.
3. Which kind of air mass(es) is most likely to bring a drought? Why?
Continental tropical,because its warm and dry air.
4. Which kind of air mass(es) bring lake-effect snowstorms? (check p. 561)
Continental polar bring lake-effect snowstorms.
5. Today we learned about the 4 main types of air masses. In reality, there are many more than four. List and explain 2 other air masses.
Arctic-The source region for A air is northern Canada.It has the same characteristics as Polar air except it is colder with even lower dewpoints.
Highland-This air mass occurs in regions with large elevation changes over short distance. It is not a source region for one particular type of air mass.

1.What is "IR" raditation?
"IR" raditation is infared raditation.
2. What are the 3 main greenhouse gases?
the three main greenhouse gases are carbon dioxide,methane and water.
3. In your opinion, is the greenhouse effect a good thing or a bad thing?
I think greenhouse gases are a bad thing because it is causing global warming.

1. Most people agree that recycling is a good thing. Why, specifically should we recycle glass?
We should recycle glass because Every ton of glass recycled saves the equivalent of 9 gallons of fuel oil needed to make glass from virgin materials. At least 30% of glass containers on grocery store shelves can be recycled. Container glass can be recycled repeatedly with no loss of quantity or quality.
2. Which is better: recycling or reusing things?
I think that recycling is better then reusing,because when you reuse items it causes bacteria to grow and spread. Not only that you could get sick from the bacteria.
3. How can Fayetteville residents recycle?
Fayetteville residents can separate the glass, plastic, cardboard, and aluminum, then put them in different containers.
4. Where is the closest recycling drop-off center to your home (or our school)?
Parker Site-4759 Black Bridge Rd Hope Mills, NC
is the closet to my house.
5. List 9 things plastic can be made into once it has been recycled.
Recycled plastics can be made into bottles, shower stalls, recycling bins, scouring pads, paint brushes, industrial strapping, drainpipes, plastic lumber, flowerpots, etc.
6. List 5 things metals can be turned into once it has been melted down.
Metal is melted down and reformed into new products such as cans, automobile parts, siding, appliances and building materials.
7. What can you do to promote recycling?
I can show and tell what might happen to our planet earths atmosphere if we don't recycle.

1. How can scientists tell the age of a tree by looking at the rings? Explain what that means.
Scientists can tell the age of a tree by seeing that the rings toward the center are older then the ones toward the outside.
2. How/why would this be useful?
This is useful by knowing how long this tree has been here for and to show if it a different type of tree.

3. Is this an example of relative or absolute dating?
This is an example of absolute dating.

Destruction!-9/18/09

I think the potentially most dangerous is volcanoes.Because it will cause you to lose you home due to fires Not only that lava will burn anything in its path including humans. An example of an major volacanoe would be in russia when six volcanoes errupted in a remote region of Kamchatka. Volcanologist Yaroslav Muraviyev says so much activity was last recorded 55 years ago.

the center of the earth-9/18/09

1. How deep is the deepest mine in the world?
the deepest mine is the TauTona gold mine in South Africa, a mere 3.6 kilometers deep
2. How deep would you have to dig to reach the mantle?
In order to be able to dig down to the center of the Earth, my friends and I would have needed to dig our way through 6,378 km of rock, mantle
3.If you were somehow able to reach the mantle, what would it look like? What kinds of things would you see? How about the outer core? Inner core? What would it look like as you approached the surface (the crust) on the other side?the mantle would look like a huge chunk of rock and iron.the outer core would look like huge hot red rock,a red hot ocean.it would look like a a water falling out a funnel

Minerals and their Uses-8/20/09


Choose five minerals, and name their common use. Only choose minerals that you actually use. Also post a picture of one.

Quarts can be used in jewelry as gems. Talc is used in baby powder. Fluorite is used in toothpaste (in which we really do need!). Graphite is used in our pencils (in which we also really need). Jewelry can contain the industrial mineral diamond.
