Transform (conservative)
New land is created
Explosive volcanoes with sticky lava
Land is destroyed
Earthquakes, no volcanoes
The denser oceanic plate is subducted and melts
Magma wells up to fill the gap – pillow lava under the ocean
Runny lava means that volcanoes are effusive rather than explosive
Rift valleys on land
Two plates move apart
Fault lines – such as the San Andreas Fault
The Pacific Ring of Fire, for example
Powerful earthquakes as the crust sticks and pressure builds
Two plates collide
Plates move in opposite directions, or at different speeds
