1.1C tectonics

How big are eruptions at Divergent margins?

small and effusive

Why are eruptions small?

basaltic lava has a low gas content and high viscosity

Features of Earthquakes at Divergent margins

Shallow, less than 60km deep and under 5.0 magnitude

What plate combinations can we have at Divergent margins?

Oceanic-oceanic and Continent-continent

What are collision zones?

occurs when tectonic plates meet at a convergent boundary both bearing continental lithosphere

Features of collision zone earthquakes

Shallow, high magnitude

What plate combinations can we have at Collision margins?

Oceanic-oceanic, Continent-continent, Oceanic-Continent

Features of Conservative boundary earthquakes

shallow, high magnitude, destructive

What plate combinations can we have at Conservative margins?

Oceanic-continent
