Why do volcanoes erupt?

Magma is a liquid. It is stored within the crust and because it is a liquid, it is less dense than the surrounding rock. Therefore, it is going to rise buoyantly through the crust toward the surface. When it gets to the surface, the pressure inside that intrusion of magma gets so high that it finally exceeds the ability of the rock to hold it in. So essentially, volcanoes erupt when the magma, gets so close to the surface that it punches out.

What are Plate Tectonics?

A theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.

Why tsunami occurs after earthquake?

When a great earthquake ruptures, the faulting can cause vertical slip that is large enough to disturb the overlying ocean, thus generating a tsunami that will travel outwards in all directions.
