Shield volcanoes produce flows of mafic lava, also called basaltic lava, which has a lower viscosity and low silica content. Oceanic crust has the same composition and so it is fairly easy for shield volcanoes to form here. Continental crust has a higher silica content. As a result, many continent based volcanoes produce much more viscous lavas which produce stratovolcanoes rather than shield volcanoes.

Can volcano happen on flat land?
Yes, volcanoes can happen on flat land or rugged land, in the ocean or lakes. Volcanoes are caused by magma, molten rock, rising to or near the surface. The magma has different composition and can be very thick or thin like the Hawaiian volcanoes.
Why do cinder volcanoes have narrower bases and steeper sides than shield volcanoes?
shield volcanoes have cinders that come out then land on it. that's what makes them bigger than cinder cone volcanoes.

Do volcanoes occur in oceans and earthquakes occur on land?
Earthquakes and volcanoes both occur in land and ocean. =)
What is the difference between Compare volcanoes that form on land with volcanoes that form in the ocean.?
Land Volcanoes eat lamas and underwater volcanoes eat camals
Are most volcanoes form on land?
nope, ocean trenches
Why do cinder cones volcano have narrower bases and steeper sides than shield volcano do?
shield volcanoes have cinders that come out then land on it. that's what makes them bigger than cinder cone volcanoes.
Which ocean has a ring of volcanoes on the land surrounding it?
The Pacific Ocean has a ring of volcanoes known as the Ring of Fire. This area is located in the Pacific Ocean basin and is characterized by frequent earthquakes and volcanic activity due to plate tectonics.
Where are the main functioning volcanoes?
Most of the functioning Volcanoes today are in Indonesia ( Land ) Underwater most are in the Pacific Ring of Fire ( Ocean )
What would happen if no more volcanoes erupted?
Not much; this would mean no more landforms would be built on the ocean. Ex: Islands. There would be less damage if there were some to erupt on land.
What will happen when ocean to ocean plates converge?
it creates more land
Why do cinder volcanos have narrow bases and steeper sides than shields volcanos do?
shield volcanoes have cinders that come out then land on it. that's what makes them bigger than cinder cone volcanoes.
