Mapping The Ocean Floor Worksheet Unit 7 The Ocean Floor This unit depicts the topography of the ocean floor and describes how the features of the ocean floor are formed 1 State the features that make up the topography of the ocean floor 2 Explain how the features of the ocean floor are formed 3 Examine a profile of the topography of the ocean floor and label its features
4 On the Mapping the Ocean Floor Lab handout plot the Distance from Beach x axis vs Ocean Depth y axis for the Atlantic Profile graph Sea level 0 meters is the line already shown on the graph 5 Once the points are plotted connect the points and shade in the profile of the ocean floor 6 The seafloor is covered with interesting geologic features from trenches to seamounts but we have only mapped 20 of the global ocean There is still much work that needs to be done before we have a complete view of the seafloor and its features In the following lesson students learn how to become bathymetry experts and use real mapping data

After an introduction in which students try to identify hidden objects by the sounds they make when shaken in a box students use string to map a model ocean floor by taking depth readings to simulate sonar Source COSEE Central Gulf of Mexico Subjects Earth Science Math Technology Grades 3 5 Legs the two sides of a right triangle opposite the non right angles Pangea a supercontinent that formed about 300 million years ago and broke apart about 175 million years ago pressure a force exerted on an object by something in contact with it salinity amount of salt in a body of water sonar a way to measure depth under water using
MAPPING THE OCEAN FLOOR OVERVIEW During this lesson students participate in a simulation of the pre sonar method of mapping underwater terrain OBJECTIVES Following completion of this lesson the students will be able to Develop the understanding that the bottom structure of underwater habitats can be mapped The seafloor has distinct features and characteristics that help us better understand Earth s current and past conditions potential resources and natural hazards However less than 10 of the seafloor has been mapped globally The USGS conducts high resolution mapping to describe the physical features of the ocean floor as well as the geologic layers and structure beneath it
