Question

what is a divergent boundary?
divergent boundary | diagram/sketch | feature formed
continent to continent
ocean to ocean

Explanation:

First, a divergent boundary is a tectonic plate boundary where two plates move away from each other. For continent-to-continent divergent boundaries, the continental crust stretches and thins, creating a rift valley. For ocean-to-ocean divergent boundaries, magma rises from the mantle to fill the gap, forming an underwater mountain range called a mid-ocean ridge.

1. Continent to Continent:

• Diagram/Sketch: Draw two thick continental plates moving apart, with a sunken, linear rift valley between them, and small upward arrows indicating the plates moving away from each other.
• Feature Formed: Rift Valley (e.g., East African Rift Valley)

1. Ocean to Ocean:

• Diagram/Sketch: Draw two thin oceanic plates moving apart, with a raised, linear ridge between them, red arrows showing magma rising from below to create new crust, and outward arrows for the moving plates.
• Feature Formed: Mid-Ocean Ridge (e.g., Mid-Atlantic Ridge)

Answer:

What is a divergent boundary?

A tectonic plate boundary where two plates move away from one another, with magma rising to fill the resulting gap.
