This map shows a part of the sea floor.
Sea floor topogrpahy activity.
The under water topography maps have been developed by the study of ocean floor topography.
What is the ocean depth if the signal time of return is 5 4 seconds.
The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
Identify the following features.
Ocean floor topography sonar activity 2.
Obtain a 3 dimensional seafloor model in a box covered with paper from your teacher.
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.
Ocean floor topography involves the study of ocean bottom features including the outer continental shelf continental slopes and ocean waves desktops.
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.
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.
Exercise 18 1 visualizing sea floor topography.
This study is extensive and it has been established that the ocean floor has similar features of mountains and valleys as on the earth.
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 map images and activities in this packet can be used in various courses including geography history math art english and the sciences.
This assignment even connects seafloor features with plate tectonic boundaries.
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.
Constructing a 3d topographic map activity this exercise uses clear plastic take out lids each marked with a different elevation line and stacked to produce a 3d topographic map.
The paper represents the water surface.
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.
Distance rate x time depth time x velocity speed of sound in ocean 1 524 m s example problem.
Ocean floor topography and features 1.
The topography of the northern atlantic ocean is shown in figure 18 1 1.
