What are 3 things that causes a volcano a tornado a typhoon a hurricane and an earthquake?

Answer 1

Aside from hurricanes and typhoons, which are essentially the same thing, all of these have different causes. Here is each phenomenon simplified down to three causal factors.

Hurricanes/typhoons:

1. Warm ocean water to power the storm
2. Earth's rotation to set the storm spinning
3. A disturbance to act as a "seed"

Tornadoes:

1. Thunderstorms fueled by unstable air
2. Wind shear to set storms spinning
3. A downdraft to torn the rotation into a tornado

Volcanic eruptions:

1. A source of magma (plate boundary or hot spot)
2. A pathway to the surface
3. Pressure from overlying rocks and trapped gasses

Earthquakes:

1. Movement in the Earth's crust to create stress
2. A fault for that stress to act upon
3. Slipping of rock on either side of the fault
