Sea Floor Topogrpahy Activity
Sound navigation and ranging 3.
Sea floor topogrpahy activity. 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. Ocean floor topography and features 1. Obtain a 3 dimensional seafloor model in a box covered with paper from your teacher.
Ocean floor topography involves the study of ocean bottom features including the outer continental shelf continental slopes and ocean waves desktops. What is the ocean depth if the signal time of return is 5 4 seconds. Exercise 18 1 visualizing sea floor topography. The under water topography maps have been developed by the study of ocean floor topography.
This map shows a part of the sea floor. Distance rate x time depth time x velocity speed of sound in ocean 1 524 m s example problem. 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. 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.
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. The topography of the northern atlantic ocean is shown in figure 18 1 1. 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. Ocean floor topography sonar activity 2.
This study is extensive and it has been established that the ocean floor has similar features of mountains and valleys as on the earth. 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 paper represents the water surface. This assignment even connects seafloor features with plate tectonic boundaries.
Identify the following features. 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.
