Activity On Parts Of The Ocean Floor

Mid ocean ridge activity this activity consists of naming the continents identifying mid ocean ridges and determining the age of the ocean floor.

Activity on parts of the ocean floor.

The terrain or land relief is the accumulation of forms that exist on the surface of the earth. 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. There are four basic types of sediment of the sea floor.

The ocean floor is called the abyssal plain. 2 biogenous material is the sediment made up of the hard parts of sea animals that accumulate on the bottom of the ocean. Below the ocean floor there are a few small deeper areas called ocean trenches. From land the ocean all looks the same.

Today much of our exploration of the oceans happens using sonar and remotely operated vehicles. With the advancement in technology scientists are hopeful that the oceanic depths will be explored thoroughly. Once you have labeled each map correctly you should be able to answer the series of questions that follow. Deep in the pacific ocean near china is the mariana trench the deepest part of the ocean.

Winds water density and tides all drive ocean currents. 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. Features of the ocean include the continental shelf slope and rise. As plates converge one plate may move under the other causing earthquakes forming volcanoes or creating deep ocean trenches.

The deep layers have unique sea creatures freezing temperatures and high pressure. Join jessi and squeaks and learn all about the super cool super. Earth s rotation results in the coriolis effect which also influences ocean currents. 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.

Features of the ocean floor. But underneath that surface there s a lot of stuff hidden at the bottom. 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. 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.

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.
