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.
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 sonar activity 2.
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.
This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.
Identify the following features.
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.
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.
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.
This map shows a part of the sea floor.
This assignment even connects seafloor features with plate tectonic boundaries.
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.
This study is extensive and it has been established that the ocean floor has similar features of mountains and valleys as on the earth.
What is the ocean depth if the signal time of return is 5 4 seconds.

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.
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.
