Mapping the Ocean Floor
SC.8.N.3.1
Purpose: In this lab you will use sonar data from the Atlantic Ocean to make a profile of the ocean bottom.
Procedure:
- Plot each data placing the distance east of New Jersey in X-axis, and the depth to the ocean floor, starting from zero downward, in the Y-axis.
- Plot each data point and connect the points with a smooth line
- Color the water blue and the seafloor brown.
Conclude and Apply
- What ocean floor structures occur between 160 km and 1050 km east of New Jersey?
- What ocean floor structures occur between 2000 Km and 4500 km?
- What ocean floor structures occur between 5300 km and 5500 km?
- When a profile of a feature is drawn to scale, the horizontal and vertical scales must be the same. Does your profile give an accurate picture of the ocean floor? Explain.
