Lesson Details
Key learning points
- Conservative plate margins involve two plates sliding alongside each other.
- Distinctive processes occur at conservative plate margins.
- Earthquakes occur at conservative plate margins but volcanoes do not.
Common misconception
Volcanoes occur at all plate margins.
While volcanoes are a feature of both destructive and constructive plate margins, there are no volcanic eruptions at conservative margins because no magma is produced.
Keywords
Magnitude - a measure of the energy released by an earthquake; a higher magnitude means a stronger earthquake
Magma - molten rock found beneath Earth's surface. It is formed when rocks in Earth's mantle or crust melt due to high temperatures and pressure
