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.

Some Volcanoes erupt while some don't because there are alot of different volcanoes but they all do the same thing.


No, not all volcanoes would erupt the same way. Some volcanoes erupt by explosion while others barely trickle lava down the volcano.


It depends on the volcano. Some volcanoes can erupt very often, while others will only erupt once every hundred years.


volcanoes that don't erupt in a while is called dormant.volcanoes that don't erupt anymore are called extinct.volcanoes that erupt regularly are called active.


Dormant volcanoes don't erupt at all. When volcanoes are dormant, are "asleep" and do not erupt for a while. actually yes dormant is asleep but they can erupt at any time your thinking extinct valcanos dont erupt


Volcanoes erupt infrequently more destructive and active than volcanoes that erupt continuously because the volcano that didn't erupt in a while had more pressure than the volcano that erupts constantly. When more pressure builds up, gas wants to get out as soon as possible. When it does, the magma comes out, it pushes and pushes out since all thee pressure builded up.


Yes they are. A volcano that is not erupting is called a dormant (meaning sleeping) volcano, while one that is erupting is called an active volcano.


There are alive volcanoes and dead volcanoes. So they can be either. They can also be dormant, where they've been inactive for a while but they might erupt again.


Different volcanoes have different eruption patterns. Some are very active, while some erupt once every thousand years


dormant, either in cative or only a few more times


Some volcanoes are active, while others are dormant.


It's the molten rock that comes out of volcanoes when they erupt and that streams downhill while it's still so hot that it is liquid.


A dormant volcano is a volcano that has not erupted for a while but has the possibility of doing so in the future. An extinct volcano is a volcano that will not erupt again.


On average there are about 50 volcanic eruptions recorded each year, but they are from different volcanoes. It is doubtful that any volcano would erupt 5 times every year. Volcanoes can enter into different phases of activity and no two volcanoes are alike. One volcano may erupt every few years while another may go thousands of years without erupting. A volcano may erupt many times in a relatively short time as part of a phase of activity or, in the case of kilauea, sustained a single continuous eruption for a long time.


Some volcanoes are active, while others are dormant.


When lava in volcanoes erupt, it cools in a short while so you would be able to touch it without burning your hands off.


Active volcanoes are found on mainly plate margins, with the few examples of hot spots all over the place (e.g. Moana Loa on Hawaii). Volcanoes found at constructive plate margins are more effusive and erupt basaltic lava (e.g. Iceland) and volcanoes found NEAR destructive plate margins are explosive and erupt either andesitic or rhyolitic lava (e.g. Mount Saint Helens-however this volcano might not erupt for quite a while whereas the other two example erupt very frequently).


While many volcanoes are harmful to humans, some volcanoes such as those that erupt under water in the middle of the ocean would not be harmful at all. Some volcanoes help by providing much needed hot water supplies, and volcanic material can break down into fertile soil.


They are different because earthquakes require transform boundaries to occur and volcanoes require convergent and divergent boundaries to occur. Also, earthquakes shake the ground and knock over buildings while volcanoes erupt slowly and melt some things.


Active Volcanoes - Those volanoes which has erupted in the recent history and will continue to erupt further is known as an active volcano. Dormant Volcanoes - Those volcanoes which hasn't erupted in the recent past but has the capability of erupting in the future. These volcanoes generally erupt after long intervals of time. Extinct Volcanoes - These volcanoes used to erupt but hasn't erupted in the recent past and will probably not erupt further. There are actually only 3 types of volcanos, while one can be called two things. The first kind is called shield, it is almost shaped like an upside down bowl. The second is called a cinder cone, it's sides are a little more steep and instead of squirting out just lava, its squirts out pyroclastic material also and it has moderately explosive eruptions. The last is known as a composite or a stratovolcano, with quite steep sides.


Some are. Most volcanoes on land are produced by convergent boundaries while others form over hot spots.


No. While volcanoes can erupt very hot material, a volcano that is not actively erupting may not be any warmer than an ordinary mountain. Even on an active volcano, temperatures away from the vent may be normal.


They are both tectonic faults.The volcanoes erupt in a cone with flow of magma while the plate boundaries may shift to push or overlap in folds to buckle and cause earthquakes or the lava to flow on surface.


The lava/magma comes from the earth's core, not usually stored within a volcano. "Dormant" volcanoes are "sleeping" Don't usually erupt, haven't for a while, and aren't expected to erupt any time soon. If a volcano is considered completely dead, the techtonic plate that the volcano was first formed on has moved, therefore cuts it off at the base. With this in mind, it still might have liquid magma within it, but would cool and turn back to rock eventually, and not able to erupt again.


Ol Doinyo Lengai is a unique volcano in that it erupts carbonatite lava, which cools to form carbonatite. It is unusual in that all other currently active volcanoes erupt silicate based material while this is carbonate based.
