Study Notes
Divergent Boundaries Overview
- A divergent boundary is the location where two crustal plates separate.
- This process primarily happens along oceanic crusts, forming mid-oceanic ridges.
Formation and Features
- Divergent boundaries lead to the creation of volcanic islands when plates move apart, allowing molten lava to rise and fill the gaps.
- Active divergent boundaries are characterized by cracks in the ocean floor, which occurs due to weaknesses in the crust.
Mechanics of Divergence
- As massive tectonic plates shift and spread apart, they create a gap that allows magma to ascend and fill the void.
- This upwelling magma cools and solidifies, forming new crust.
Types of Divergent Boundaries
- There are two main types of divergent boundaries: oceanic and continental.
- Oceanic divergent boundaries are thinner compared to continental divergent boundaries.
- The plates typically move in lateral directions (left and right) away from each other.
Geographical Context
- Most divergent boundaries are situated on the ocean floor, where they are predominantly found between oceanic plates.
