Sea Floor Topogrpahy Activity

Ocean floor topography involves the study of ocean bottom features including the outer continental shelf continental slopes and ocean waves desktops.

Sea floor topogrpahy activity.

Identify the following features. Exercise 18 1 visualizing sea floor topography. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Distance rate x time depth time x velocity speed of sound in ocean 1 524 m s example problem.

This study is extensive and it has been established that the ocean floor has similar features of mountains and valleys as on the earth. The under water topography maps have been developed by the study of ocean floor topography. Researchers have built a detailed map of the ocean floor s topography by using satellites to spot subtle watery lumps on the ocean s surface. The paper represents the water surface.

A a continental shelf b a continental slope c a spreading ridge d a subduction zone with a deep trench e an abyssal plain and f some isolated seamounts. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. 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 bathymetry from an oceanographic perspective. Your job is to investigate your seafloor effectively reporting back to the funding agency on prominent sea floor topography so that you can request additional funds.

Ocean floor topography and features 1. Sound navigation and ranging 3. This assignment even connects seafloor features with plate tectonic boundaries. Ocean floor topography sonar activity 2.

The topography of the northern atlantic ocean is shown in figure 18 1 1. The team also reports the exact location of a now extinct seafloor spreading ridge a zone where two tectonic plates began pulling apart 180 million years ago to form the deep basin that became. What is the ocean depth if the signal time of return is 5 4 seconds. Obtain a 3 dimensional seafloor model in a box covered with paper from your teacher.

The map images and activities in this packet can be used in various courses including geography history math art english and the sciences. In this activity students will be modelling how undersea seafloor features look like with clay then drawing the seafloor and answering questions upon their experiences and diagrams included in the assignment.
