I think there would be a crack in the earths crust so the magma can come out.

Yes. If it doesn't erupt and never has erupted then it is not a volcano.

Yes. Shield volcanoes erupt basaltic lava, which is runny.

The tectonic plates shifting is what causes an underwater volcano to erupt. Plate shifting is also the cause of tsunamis and earthquakes.

What usually causes a volcano to erupt like Eyjafjallajokull is a slight disturbance in the ground.

Shield Volcanoes erupt less violently and flows further then composite volcanoes. A composite volcano erupts more violently.

You've got to be kidding me. A volcano that erupts often is called a cinder cone volcano, a volcano that does not erupt at all is called a shield volcano, and a volcano that can erupt but doesn't is a composite volcano. Here is the chart. Cinder cone: eruption Shield: dead Composite: sleep Hope you use my answer wisely. NOOBS!

magma and heat pressure

It cause by the volcano erupt

Shield volcanoes erupt all the time - in fact, a volcano may be erupting as I type this answer! Considering this, I am not able to give you an accurate answer.

Godzilla swims around and causes it to erupt.

Not usually. Although ash producing eruptions can happen occasionally, the main products of a shield volcano are lava flows and sometimes lava fountains.

Generally shield volcanoes do not explode. They erupt in a non-explosive fashion, fountaining or oozing lava.

Yes, because a shield volcano is much closer to the ground then the other two types of volcanoes.

This is because of the time of volcano it is and the type of lava it excretes. A steep volcano will erupt with basaltic lava which is runny and can clog at the top. A shield volcano, however is different as the thick lava emitted just glops onward.

The volcano wil erupt soon. The volcano is about to erupt!

People can predict if a volcano will erupt but not when it will erupt.

An active volcano can erupt at anytime.

A volcano can maybe erupt again.

A volcano that has not erupted in a long time is dormant. A volcano that will not erupt is extinct.

It depends, a volcano can erupt once and never erupt again. Or, a volcano can erupt multiple times a day.

Maybe, as seismic movement may cause magma to push up into the volcano core and build up so much it causes the volcano to erupt.
