Oceanography Fav

My favorite subject in oceanography was studying offshore drilling i liked this topic because we had a chance to see how it was affecting our community and our planet. My favorite subject in geology was learing about how fossils and other remains can show what time of history something happened in. My favorite part of astronomy was learnig about characteristics of the sun since it was such a unique topic. My favorite topic about metorology was learning about the many, many, many diffrent types of clouds and knowing what type of precipitation they will bring.

Offshore Drilling

Offshre drilling is the drilling off of continental shelfs in the ocean to find oil.

Offshore driling is bad because it cans damage marine life.

Offshore drilling is good because it can produce more oil for the U.S and thus cause the U.S to be less dependent on other countries.

I feel that offshore drilling is not a good option because it would damage marine life and for countries that depend on seafood for their foodsource.

H-R Diagram

1.The main sequence of an H-R diagrams is the arrangement of stars in the diagram.

2.90 precent of stars are mian sequence stars.

3.Yes the Sun is a main sequence star.

4. The next thing that will happen to the sun is that is will become a redgiant.

5. The picture to the left shows an H-R diagram. As you can see the sun is aprt of the main sequence. This Graph shows you the relationship between absolute magnitude and temperature of a star.

Astronomy Topics

The Black Hole

The black hole is the densit place in the universe. The gravitational force of a black hole is so strong that nothing can escape from it.Black holes form when a stars nuclear fuel runs out and is crushed by its own gravitaional force. The event horizion is the surface of the black hole. The point of singularity is in the inside of the black hole and is made up of all the holes mass. The way these to relate is because once you hit the event horizion you immediatly goto the point of singularity.

Star Consellations

Star consellations have been used since 4000 B.C., they have been documented by the Mesopatimians. The constelations were used to tell stories and to try to predict peoples futures. A few examples of consellations are Ursa Minor, Ursa Major, and Polaris. Polaris is a well known constalation. It is known as the north star because it is almost above the northern pole. You can tell which star it is because it is almost the brightest star in the area.

Worm Holes

Worm holes are structures that connect two regions that are distanced or unrealated. Worm holes have been disscued to be a source of time travel. Scientist aren't sure if it is possible because it has never been experimented, but they do think it is required. There are many diffrent hypothesis on these wormholes.

Pluto

Pluto is classified as a dwarf planet. It is much smaller than all the other planets and orbits beyond Neptune. Pluto was descuverd in 1930. After pluto was desuvered they decided it couln't be a planet because its composition is ice and rock. In fact Pluto is known to be just a part of the Kuiper belt.

The Moon

The moon is Earths only sattelite. Most of what we know about the moon comes from the apollo missions. The moon has many features such as craters which are depressions in the moons surface. Highlands are a side of the moon which is covered in mountains. Maria is a ancient bed of basaltic.
