This image of south america was generated with data from the shuttle radar topography mission srtm. Estimate the age of the ocean floor bedrock at point x. The mid atlantic ridge a long submarine mountain range can be seen running down the centre of the atlantic ocean. Complete the topographic profile of the atlantic ocean floor between south america and a frica.

False most of the continental area of pangaea was located in the southern hemisphere. This map is centred on the atlantic with north and south america at left and africa at right. 18 1 the topography of the sea floor we examined the topography of the sea floor from the perspective of plate tectonics in chapter 10 but here we are going to take another look at the important features from an oceanographic perspective. For this broad view the resolution of the data was first reduced to 30 arcseconds about 928 meters north south but variable east west matching the best previously existing global digital topographic data set called gtopo30.

The topography of the northern atlantic ocean is shown in figure 18 2. Zoom in enough to see that although the ridge is a topographic high it also has a valley the rift valley running along the middle of it. If the earth s lowest spots aren t in the middle of the ocean where are they. Points a b and x represent locations on the ocean floor.

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Scan around to see the ocean ridges in the indian pacific and southern oceans.

If the earth s lowest spots aren t in the middle of the ocean where are they. The remnants of a former land bridge between africa and south america can be seen today on the floor of the atlantic ocean just south of the equator. The map shows a portion of the atlantic ocean floor between south america and africa. In the space below complete the topographic profile of the atlantic ocean floor between south america and africa.

Isolines show the approximate age in million years of the ocean floor bedrock on each side of the mid atlantic ridge. Zoom in enough to see that although the ridge is a topographic high it also has a valley the rift valley running along the middle of it. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
