Divergent boundary features part 1: features at divergent boundaries below is a cross section of a divergent plate boundary. the ocean surface is indicated by a dashed line. 1. draw a vertical line across the divergent plate boundary on the diagram. 2. on each plate, draw one arrow showing the direction it is moving. 3. draw one arrow in the mantle below the lithosphere (colored gray) showing the direction the mantle is moving. 4. circle the two features that can be found of divergent plate boundaries. deep ocean trench ocean ridge mountain range subducting plate lava 5. label the cross section above with your circled features. 6. three students are discussing one of the features you find at a divergent plate boundary. student 1: there is a ridge because the two plates are being pushed up by the hot mantle where it rises to fill in the gap as the plotes spread apart. student 2: there is a ridge because the two plates are pushing together, and they run into each other causing them to get pushed up like two slabs of rubber. student 3: there is a trench because the two plates are pulling apart, leaving behind a large, very deep crack between them called a trench. with which student do you agree? why? © w. h. freeman and company lecture tutorials for introductory geoscience 37.
