Activity on parts of the ocean floor.

The deep layers have unique sea creatures freezing temperatures and high pressure. Today much of our exploration of the oceans happens using sonar and remotely operated vehicles. Below the ocean floor there are a few small deeper areas called ocean trenches. As plates converge one plate may move under the other causing earthquakes forming volcanoes or creating deep ocean trenches.

Where plates diverge from each other molten magma flows upward between the plates forming mid ocean ridges underwater volcanoes hydrothermal vents and new ocean floor crust. Includes information about the different parts of the ocean floor continental margin including the shelf slope rise and abyssal plain discusses the difference between passive and active margins and underwater land features. 2 biogenous material is the sediment made up of the hard parts of sea animals that accumulate on the bottom of the ocean. Similar to a person trying to walk in a straight line across a spinning merry go round winds and ocean waters get deflected from a straight line path as they travel.

With the advancement in technology scientists are hopeful that the oceanic depths will be explored thoroughly. But underneath that surface there s a lot of stuff hidden at the bottom. Features of the ocean include the continental shelf slope and rise. The terrain or land relief is the accumulation of forms that exist on the surface of the earth.

There are four basic types of sediment of the sea floor. The ocean is also part of the earth s surface and just as there are volcanoes mountains plains and other visible formations on land the same exist underwater although not everything in the ocean is completely mapped. The ocean floor is called the abyssal plain. 1 terrigenous describes the sediment derived from the materials eroded by rain rivers glaciers and that which is blown into the ocean by the wind such as volcanic ash.

Winds water density and tides all drive ocean currents. Deep in the pacific ocean near china is the mariana trench the deepest part of the ocean. Earth s rotation results in the coriolis effect which also influences ocean currents. Coastal and sea floor features influence their location direction and speed.

Once you have labeled each map correctly you should be able to answer the series of questions that follow. Features of the ocean floor. It s flat blue and honestly it s kind of boring. The layers range from the surface layer where most ocean activities occur to the deep dark depths of the water that have yet to be fully explored.

Scientific research submersibles have explored the ocean s deepest trenches but most are designed to reach only the ocean floor.
