What is the Process that causes earthquakes and volcanoes?

Answer 1

Earthquakes are caused by transform faults and when stress overcomes friction.

volcanoes are caused by convergent boundaries, the process of convergent boundaries is when two plates come in contact with each other. ex. for volcano is a oceanic plate sub ducts under a continental plate.

Answer 2

An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.

A more technical description is given below:

Earthquakes are tremors or vibrations in the Earth's crust that are caused by the build up or accumulation of pressure (more correctly termed stress).

This accumulation of stress causes the rocks that make up the crust to deform elastically. This is very similar to what happens when you squash or stretch a spring and causes a form of energy to be stored in the rocks of the crust - technically described as elastic potential energy.

When this stress gets to large, it exceeds the strength of the rocks in the crust and causes a brittle failure. Brittle failures are failures where fractures form through the material.

This sudden brittle failure causes all of the elastic potential energy to be released at one time in the form of seismic waves, just as if a spring or elastic band that was being stretched suddenly snapped.

These seismic waves cause the tremors that people feel on the surface and which can cause damage to buildings and other structures.

Answer 3

I don't know the procedure, but I understand it involves three pounds of salt and an ornery cockatiel.

Answer 4

Earthquake is caused by disturbance in the earth's crust.

Answer 5

a fault causes earthqakes
