Mapping The Ocean Floor Graph

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.

Mapping the ocean floor graph. Topographic maps of the sea floor. The map serves as a tool for performing scientific engineering marine geophysical and environmental studies that are required in the development of energy and marine resources. Students map a section of the ocean floor. In addition they calculate the depth of two points using sonar.

On the mapping the ocean floor lab handout plot the distance from beach x axis vs. Mapping the ocean floor data and observations sketch a graph representing the first box you mapped here. The speed of sound in water is 1 454 meters per second. Ocean depth y axis for the pacific profile graph.

The ship is equipped with high tech depth sounding equipment. The problem with that approach is that our oceans are vast and ships are small meaning only a tiny percentage of the ocean floor between 5 15 percent nasa estimates was mapped. They are turned into a three dimensional model of the ocean floor. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.

Students learn that the ocean. Explain why it is different. You are a research vessel with the purpose of mapping the topography of the ocean floor across the atlantic ocean. Once the points are plotted connect the points and shade in the profile of the ocean floor.

The formula to find the ocean floor depth is d t v in the formula d stands for depth t for time between sending and receiving and v for the speed of sound in water. How does the graph the sonar reported to the computer differ from your drawing above. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. 04 mapping the ocean floor lab you 04 mapping the ocean floor lab pdf.

Sketch a graph representing the second ocean floor you created here. 04 mapping the ocean floor lab you 04 mapping the ocean floor lab pdf modelling the ocean floor lab mapping the ocean floor worksheet page 1. Detailed depth contours provide the size shape and distribution of underwater features. Mapping the ocean floor for teachers4th 12th students construct and interpret a line graph of ocean floor depth and a bar graph comparing the height depth of several well known natural and man made objects and places.

For this set of data the depth has already been calculated for you. Teams are given a series of depth data sheets to graph. The table below gives you some more sonar sounding data. What was the mean of the three boxes.
