Hazards
Tropical Cyclones
Warm air currents rise from the ocean.
As the warm air rises, more air rushes in to replace it: then it too rises, drawn by the draught above.

-
-
As the tropical cyclone tracks away from its source, it is fed new heat and moisture from, oceans enlarging as it goes.
Air pressure rises as temperature falls, winds drop, rainfall decreases, and it decays to become a normal storm.
-
Tsunamis
-
The ground is pushed up by the earthquake, shifting lots of water and causing a wave to form.
-
-
The back of the wave is still travelling faster than the front, so rises into a massive wave
The massive wave hits the shore and travels inland, destroying objects and buildings in its path.
plate boundaries
Divergent Plate Boundary
-
Volcanoes are formed as magma wells up to fill the gap, and eventually new crust is formed.
-
Collision Plate Boundary
Collision zones form when two continental plates collide. Neither plate is forced under the other, and so both are forced up and form fold mountains.
