Atlantic Ocean Floor Diagram

Running along the crest of the ridge is a long valley that is about 50 to 75 miles 80 to 120 km wide.

Atlantic ocean floor diagram. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. This diagram provides evidence of seafloor spreading by showing the ages of ocean floor in the atlantic and eastern pacific oceans. The mid atlantic ridge for instance separates the north american plate from the eurasian plate and the south american plate from the african plate the east pacific rise is a mid ocean ridge that runs through the eastern pacific ocean and separates the pacific plate from the north american. The image shows the mid atlantic ridge a submarine volcanic mountain belt that is a key location in the process of.

The outstanding feature of the atlantic floor is the mid atlantic ridge an immense median mountain range extending throughout the length of the atlantic claiming the centre third of the ocean bed and reaching roughly 1 000 miles 1 600 km in breadth. The mid atlantic ridge is located at the juncture of crustal plates that form the floor of the atlantic ocean. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. It is more than 970 kilometres 600 mi long and 580 kilometres 360.

It is considered a slow spreading ridge by earth scientists. The topography of the northern atlantic ocean is shown in figure 18 1 1. Smooth regions of the ocean floor are aleld abyssal plains. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet.

The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. The red colors are the youngest parts of the seafloor where fresh new crust is formed as lava seeps up from the deep interior of the earth at spreading ridges as new crust forms at these spreading ridges older crust colored green in the diagram moves away from. In this video we will study about the ocean floor and the different physical landform which exist on the ocean floor. Using the diagram with the figures labelled a b and c from left to right match the name of the plate boundary with its figure letter.

Ocean floor is composed of various kind. Be careful when interpreting this diagram and others like it because in order to show the various features clearly the vertical axis is exaggerated in this case by about 200 times.
