What is occurring at locations where two plates are moving away from each other?
Lesson Objectives...
Support or refute a claim orally and in writing, based on evidence from multiple locations over a large distance along the ridge to explain what is happening where two plates are moving apart.
Compare data and evidence from the case cards and the Mid-Atlantic Ridge to determine that volcanoes are correlated with some cases of mountain change, but not the cause of all mountains changing.

Gather evidence from Seismic Explorer - Plate Movement to help answer our lesson question. What is happening at locations where two plates are moving away from each other? Do not forget to gather information by selecting Data Type.
Mid-Atlantic Ridge Plate Boundary...
Mid-Atlantic Ridge Plate Boundary...
Examine the area in the middle of the Atlantic Ocean, known as the Mid-Atlantic Ridge. What evidence can you gather to support what you are figuring out?
Investigate Using the Mid-Atlantic Ridge StoryMap...
Investigate Using the Mid-Atlantic Ridge StoryMap...
Gather evidence from the artifacts in the Mid-Atlantic Ridge StoryMap to support or refute your claim about the Mid-Atlantic Ridge.
If you do not have access to the Mid-Atlantic Ridge StoryMap, use this Document to gather the same evidence.
What we figured out this lesson...
What we figured out this lesson...
- Plates are moving apart along the Mid-Atlantic Ridge. (Lesson 8)
- Scientist call the place where two plates are moving apart a ridge. (Lesson 8)
- Magma from the mantle is pushing up from under the plate, which can be seen in places like volcanoes and fissures in Iceland and along ridges. (Lesson 8)
- New oceanic plate material is being formed at ridges. (Lesson 8)
- The pushing of magma on the plates causes the plates to move, which causes changes to mountains elevations and location over time. (Lesson 8)
