Rift valleys on land
Two plates move apart
New land is created

Earthquakes, no volcanoes
Explosive volcanoes with sticky lava
Magma wells up to fill the gap – pillow lava under the ocean
Most earthquakes are fairly gentle
Fault lines – such as the San Andreas Fault
Land is destroyed
Two plates collide
Runny lava means that volcanoes are effusive rather than explosive
The Pacific Ring of Fire, for example
The denser oceanic plate is subducted and melts
Plates move in opposite directions, or at different speeds
