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