Activity On Parts Of The Ocean Floor

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.

Activity on parts of the ocean floor.

Earth s rotation results in the coriolis effect which also influences ocean currents. It s flat blue and honestly it s kind of boring. Mid ocean ridge activity this activity consists of naming the continents identifying mid ocean ridges and determining the age of the ocean floor. Scientific research submersibles have explored the ocean s deepest trenches but most are designed to reach only the ocean floor.

Today much of our exploration of the oceans happens using sonar and remotely operated vehicles. The deep layers have unique sea creatures freezing temperatures and high pressure. But underneath that surface there s a lot of stuff hidden at the bottom. Below the ocean floor there are a few small deeper areas called ocean trenches.

Features of the ocean floor. There are four basic types of sediment of the sea floor. 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.

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 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. Deep in the pacific ocean near china is the mariana trench the deepest part of the ocean. The ocean floor is called the abyssal plain.

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. Join jessi and squeaks and learn all about the super cool super. With the advancement in technology scientists are hopeful that the oceanic depths will be explored thoroughly. 2 biogenous material is the sediment made up of the hard parts of sea animals that accumulate on the bottom of the ocean.

From land the ocean all looks the same. Winds water density and tides all drive ocean currents. Ocean floor reading passage interactive activity and writing prompt. 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.
