Seafloor Spreading and Subduction Science Games
In this series of games, your students will learn about the topography of the ocean floor and the tectonic processes that cause it to constantly change. The Seafloor Spreading and Subduction learning objective — based on NGSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research.
Scroll down for a preview of this learning objective’s games and the concepts they drive home.
The seafloor is made up of volcanic rock called basalt that sits under layers of sand and other sediments. The basalt is made of magma that flows up where two tectonic plates move apart — or diverge — near the center of the oceans, forming mid-ocean ridges. These ridges are home to the youngest ocean crust.
The farther you travel from mid-ocean ridges, the older the ocean crust becomes. The oldest ocean crust is located in deep sea trenches closer to continents. Here, two tectonic plates move toward each other — or converge — with one diving under the other and being destroyed in a process called subduction.
The cycle of new seafloor forming and old seafloor subducting is extremely slow, with the plates shifting just a few centimeters per year. Because it takes a long time for the crust to move, the crust at the trenches is about 200 million years old!
In total, there are nine games in this learning objective, including:
- Search For The Seafloor
- Seafloor Secrets
- Dizzy Lava
- Castle of Sand: Seafloor Spreading and Subduction
- Seafloor Adventure
- Escape!: Seafloor Spreading and Subduction
- Seafloor Explorer 9
- Something Fishy
