the fieldtrip I attended on Wednesday was at the New England aquarium. Throughout the day we had the chance to see thousands of marine organisms and mammas in the aquarium. one interesting aspect of the aquarium was the shark and ray tank, they made it look like a very limited coastal ecosystem of mangro forests. I was a little surprised to see how calm the octopus was with its habitat and it basically stayed in the same spot the whole time which I though was strange. As for the stingrays they were pretty slimy, but they had no hesitation swimming right up to your hand. As for the overall fieldtrip it was fun and I enjoyed learning a few things about some of the ecosystems.

1. Define the term salinity. The term of salinity is mainly described as relating to salt or containing salt. 2. If you add salt to a water solution, will a hydrometer float higher or lower in the water? Explain your choice. the hydrometer will float higher because there are more dissolves particles in the water causing things to float. 3. What effect does the addition of salt have on the properties of water? The vapor pressure of the water will decrease causing the boiling point to be higher and the freezing point to be colder. 4. Is it easier to float in the ocean than in a swimming pool? Explain why or why not. because the amount of dissolved particles in the ocean. 5. Define the term density. Is a physical property of matter, as each element and compound has a unique density associated with it 6. The salinity of seawater is also affected by the temperature of a body of water. Explain how temperature causes differences in the salinity of water. The amount of salt will effect the temperature of water.

Certain winds appear in certain parts of the earth. for example the trade winds are the winds that flow in the direction of the equator. I've also learned that sense the earth is on an axis it causes the wind to spin in almost a spinning motion. another thing I took away from this would be that prevailing winds blow predominantly through a single general direction across the earths surface. sense the earth is on an axis it puts the heat from the sun at an angle so it distributes across the earths surface.

By participating in the sand activity i learned how certain materials are found in certain shorelines of the earth. i also learned that alot of that has do to with fault lines near the ocean creating ether volcanic eruption or just shifting of plates. With a volcano erupting with in distance of a beach theres a chance that basalt will show up on the shoreline. Another observation i made is that most of the sand found on the earth does not nessesarily consist of magnetite. for example kabath california is more of darker sand because of the basalt compared to brazil which is more of a tan color sand.

1.An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3000 and 6000 meters. Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth’s surface. 2. A guyot is an isolated underwater volcanic mountain sea mount, with a flat top over 200 meters below the surface of the sea. 3.the continental shelf, which is an underwater extension of the coastal plain. The continental shelves are the regions of the oceans best known. 4.A submarine canyon is a steep-sided valley cut into the sea floor of the continental slope, sometimes extending well onto the continental shelf. Some submarine canyons are found as extensions to large rivers; however most of them have no such association. 5.A mid-ocean ridge is a general term for an underwater mountain system that consists of various mountain ranges (chains), typically having a valley known as a rift running along its spine, formed by plate tectonics. 6.An island arc is a type of archipelago, often composed of a chain of volcanoes, with arc-shaped alignment, situated parallel and close to a boundary between two converging tectonic plates.

feildtrip

the feild trip was fun and it kept me on my feet. i also learned quiete a few things for example tuna fish are worth up to 10,000 dollars if you were to sell it in japan. I also discovered how much wildlife you can find at the bottom of the ocean sea floor. Also everything in the ocean revolves asround the planktin considering there the bottom of the food chain.The hands on activities also gave me a better understanding about the ocean and the life thats in the water. One thing i learned was that the ways of testign water is much easier than i thought and is consistantly effective on finding the information you need to find.

what happened in Hawaii was devastating and there should be new safety precautions before doing future molasses transportations. This was a huge mistake because it wiped almost all of the underwater wild life that was around that are. Not only that the water will be contaminated for months and everything is going to have to start over where it happened.
