Topic: world ocean
Course Type: intro


Series of questions based on sediment thickness data in GeoMapApp. Questions for the students to explore in groups either in class or as homework:
1) Where is sediment cover the thickest?
2) Where is sediment cover the thinnest?
3) Any relationship between sediment cover and seafloor age?
4) Any relationship between sediment cover and proximity to continents?
5) Propose a hypothesis to explain the explored variability.


Exploration of online digital data. Studying relationships between different variables including erosion and seafloor spreading. Critical thinking. Team work.


Have students report on their findings. Compare hypotheses and discuss.
