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.
