Why are regions where convection currents diverge more suitable for building geothermal power stations?
Divergent boundaries create mountains on which to install the stations.
Energy from magma at divergent boundaries is cleaner.
Divergent boundaries are unaffected by magma convection currents.
Divergent boundaries allow heat to rise faster.
- 22. Multiple Choice
Cause: Earth is covered by a crust that runs miles deep. What's the effect?
Effect: The mantle is insulated from the atmosphere and retains tremendous heat.
Effect: Magma at the core-mantle boundary rises and convection currents are formed.
Effect: Pressure builds up, eventually leading to an earthquake.
- 23. Multiple Choice
Cause: Radiogenic heat rises to heat molten magma. What's the effect?
Effect: The mantle is insulated from the atmosphere and retains tremendous heat.
Effect: Magma at the core-mantle boundary rises and convection currents are formed.
Effect: Pressure builds up, eventually leading to an earthquake.
- 24. Multiple Choice
Cause: Tectonic plates at transform boundaries experience friction. What's the effect?
Effect: The mantle is insulated from the atmosphere and retains tremendous heat.
Effect: Magma at the core-mantle boundary rises and convection currents are formed.

Oceanic-continental convergence causes new rock to form from freshly erupted magma. Which step is first?
Rocks from the existing crust enter the mantle and undergo partial melting
The dense oceanic plate sinks beneath the buoyant continental plate, and water from the oceanic crust enters the mantle.
Continental and oceanic plates collide due to the movement of plates.
Once exposed to air, the magma cools rapidly into a solid form called rock.
The interaction of fluids and melted rocks produces molten magma. The magma breaks through Earth’s crust under enormous pressure.
