Use the model to show them the creation of new sea floor at spreading centers and the disappearance of old sea-floor at subduction zones. You may wish to cut the paper model …

Nov 29, 2023 · Seafloor spreading occurs along mid-ocean ridges—large mountain ranges rising from the ocean floor. The Mid-Atlantic Ridge, for instance, separates the North American plate …

The process of sea-floor spreading created the lithosphere under the Atlantic Ocean. As North America and South America moved away from Europe and Africa, the resulting crack was …

To construct a paper model that will illustrate how the seafloor spreads (is created) at mid-ocean ridges and is consumed (removed) where it descends into trenches.

Oct 31, 2025 · This model explained why rocks older than 200 million years had never been encountered in the oceans, whereas the continents preserve rocks almost 4 billion years old. …

Create a seafloor spreading model & calculate spreading rates. Learn about plate tectonics, subduction zones, and magnetic polarity. High School Earth Science.

A Model of Seafloor Spreading Purpose: The purpose of this activity is to make a simple model that shows the evolution of oceanic crust through sea-floor spreading.

Purpose: Students will make a paper model illustrating the concept of sea-floor spreading and the development of symmetrical magnetic "stripes" on either side of a mid- ocean spreading center.

Circulate the ribbons of paper to simulate the movement that occurs during seafloor spreading. Use your Seafloor Spreading Model to answer the questions on the next sheet.

Use the model you constructed for the Mid-Atlantic Ridge and apply it to explain diferences and similarities between the rift valleys in Iceland and East Africa.
