I think you are asking about the difference between
Explosive volcanoes that shoot off their tops, like Mt St Helens, and spread volcanic ash high into the air while dropping lava bombs nearby amongst the lava flowing out from cracks.
and
Shield volcanoes which keep adding laval in a less explosive manner so it just builds up forming a shallow cone with a hole in the center, resembling the shield of a greek warrior.
Here's how they are different:
Shield volcanoes, as in the Hawai'i have basaltic magma which is runnier than the granitc magma that rises to erupt from continental volcanoes.
Magma with lots of iron and manganese cools as it rises. Every so often, the magma gets too cold for a rock type to continues to be melted and that part makes a crystal which is solid. The crystals are left behind when the magma rises, and as it keeps moving up, more and more solids drop out of the melt.
Finally, most of the iron and magnesium dropped out as crystals and now you have the magma dregs: silica, gold, etc. beryl.
Silicate lavas are very sticky and viscous. It takes more pressure to get that sticky silicate goo upward and away from the volcano compared to eruptions of basaltic lava.
Try it yourself using sugar 2D links
1. Put a bunch of rocks on a tray
2. make fudge
3. quickly pour it over the rocks
4. compare your fudge lava to aa features in Hawaii
Silica is tougher, it has 3D links
1. set up a piece of wax paper hanging from the ceiling over a tray of water
2. melt sugar until it is a liquid
3. carefully place spoon in sugar with both hands, take up a small part of melted sugar and throw it at the wax paper
4. compare the shpae of the cooled sugar to pics of lava bombs
thats the difference - silica bonds in 3 dimensions

Are there any kind of volcanos?
There are three different types of volcanoes. The types of volcanoes are shield volcanoes, dome volcanoes, and also composite volcanoes.
What are the three different volcanoes?
The three different types of volcanoes include the following; shield volcanoes, composite volcanoes, and the cinder cone volcanoes. These all have their names because of the size and shape of the out rocks of the actual volcano itself.
What are the names of the different types of volcano formations?
shield volcanoes, composite volcanoes and cinder cone volcanoes
Why were volcanoes made?
Volcanoes are evidence of the ceaseless tectonic activity that our planet has. The molten core of the earth drives all of the processes we see, including volcanoes, earthquakes, even as high up as the northern lights. The heat that is inside of our planet is the driving force behind volcanoes, however volcanoes form in many different areas, and under many different conditions. Different types of volcanoes are evidence of different processes being present underground. However, to put it simply without the heat from the core of the earth there wouldn't be any volcanoes.
How many different shapes of volcanoes are there?
5

Why are your answers roung?
you say there is three different kinds of volcanoes when there are six different kinds of volcanoes

The three different types of volcanoes include the following; shield volcanoes, composite volcanoes, and the cinder cone volcanoes. These all have their names because of the size and shape of the out rocks of the actual volcano itself.
Why are there different shaped volcanoes?
Different shaped volcanoes occur because of the way the magma flows. Three types of volcanoes are shield, composite, and caldera.
How are underwater volcanoes different from volcanoes that are above sea level?

What are the names of the different types of volcano formations?
shield volcanoes, composite volcanoes and cinder cone volcanoes
Name the different types of volcanoes according to their shape?
There are three types of volcanoes which have different shapes and types of eruptions. * Shield Volcanoes - are low and flat and have small, flowing eruptions. * Composite Volcanoes - are a mixture between shield volcanoes and cone volcanoes, their eruptions are explosive. * Cone Volcanoes - are the tallest and largest volcanoes, and they have VERY explosive eruptions.
How many types of volocanoes are there?
There are actually quite a few different kinds of volcanoes in the world such as active volcanoes. These volcanoes include also underwater volcanoes and inactive volcanoes.
How are cinder volcanoes different from composite volcanoes?
Cinder cone volcanoes are much shorter and a little bit wider.
What variables with in volcanoes cause different types of eruptions?
The amount of gas and the pressure in the volcanoes.

Where are their the most volcanoes?
lots of different places
