Activity On Parts Of The Ocean Floor

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.

Activity on parts of the ocean floor.

Deep in the pacific ocean near china is the mariana trench the deepest part of the ocean. Join jessi and squeaks and learn all about the super cool super. Winds water density and tides all drive ocean currents. Today much of our exploration of the oceans happens using sonar and remotely operated vehicles.

It s flat blue and honestly it s kind of boring. 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. Below the ocean floor there are a few small deeper areas called ocean trenches.

Features of the ocean include the continental shelf slope and rise. Coastal and sea floor features influence their location direction and speed. But underneath that surface there s a lot of stuff hidden at the bottom. 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.

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. With the advancement in technology scientists are hopeful that the oceanic depths will be explored thoroughly. 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. Features of the ocean floor.

Ocean floor reading passage interactive activity and writing prompt. 2 biogenous material is the sediment made up of the hard parts of sea animals that accumulate on the bottom of the ocean. 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. As plates converge one plate may move under the other causing earthquakes forming volcanoes or creating deep ocean trenches.

Once you have labeled each map correctly you should be able to answer the series of questions that follow. The terrain or land relief is the accumulation of forms that exist on the surface of the earth. The deep layers have unique sea creatures freezing temperatures and high pressure. The ocean floor is called the abyssal plain.

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