What is the process at a divergent boundary?Show answer
At a divergent boundary, two plates move apart from each other, pulled by convection currents in the mantle:
What is the type of volcanic activity?Show answer
The volcanic activity at divergent boundaries is generally gentle and frequent rather than explosive. The magma is basaltic: runny (low viscosity) and low in gas, so it erupts as fluid lava that flows out and spreads rather than building up pressure. These are effusive eruptions producing gently sloping features, very different from the violent eruptions at convergent boundaries.
What are the landforms?Show answer
Divergent boundaries produce distinctive landforms:
What is q1?Show answer
State what happens to the plates at a divergent boundary. [1 mark]
What is q2?Show answer
Explain why a divergent boundary is called constructive. [2 marks]
What is q3?Show answer
Name one landform found at a divergent boundary and explain how it forms. [2 marks]
