As plates converge one plate may move under the other causing earthquakes forming volcanoes or creating deep ocean trenches.
Activity on parts of the ocean floor.
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.
From land the ocean all looks the same.
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.
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.
Once you have labeled each map correctly you should be able to answer the series of questions that follow.
Today much of our exploration of the oceans happens using sonar and remotely operated vehicles.
Coastal and sea floor features influence their location direction and speed.
Scientific research submersibles have explored the ocean s deepest trenches but most are designed to reach only 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.

Features of the ocean floor.
Below the ocean floor there are a few small deeper areas called ocean trenches.
The deep layers have unique sea creatures freezing temperatures and high pressure.
The terrain or land relief is the accumulation of forms that exist on the surface of the earth.
2 biogenous material is the sediment made up of the hard parts of sea animals that accumulate on the bottom of the ocean.
The ocean floor is called the abyssal plain.
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.
There are four basic types of sediment of the sea floor.
Deep in the pacific ocean near china is the mariana trench the deepest part of the ocean.
It s flat blue and honestly it s kind of boring.
Ocean floor reading passage interactive activity and writing prompt.
But underneath that surface there s a lot of stuff hidden at the bottom.
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 include the continental shelf slope and rise.
