volcanoes appear when two plate boundaries either move away from each other or move closer to each other. New land is made by lava solidifing in gaps in the earth. Under the sea, plates always move and lava keeps solidifing so every year, the volcano grows a couple of centimetres until it reaches the top of the sea where it starts to form new land until the lava in the magma chamber underneath the sea starts to build up pressure which sends up the lava which will set the volcano off.
some volcanoes that are on land errupt when too much pressure has been built up over hundreds of years, the top of the volcano blows off and then large clups of molten rock and ash fall from the volcano. The lava over flows and runs down the side of the volcano.
There are different types of volcanoes:
* a lava volcano is runny and spreads faster over a larger area
* an ash volcano is formed from ash and is usually steep sided. They have a large crater.
* A larger lava volcano has thick slow flowing lava that hardens quickly and forms steep sided volcanoes.
A volcano may also appear in `hotspots` this is where there is particuly hot lava under the surface toward the middle of the plate and the lava pushes up through the plate causing a volcano
Hope this helps
What else can I help you with?
Where do most volcanoes appear on the earth surfaces?
Where ever there are hotspots
Do volcanoes erupt in warm countries only?
No. Where volcanoes appear is not affected by climate. There are volcanoes in places such as Iceland, Alaska, and Antarctica.
Where do volcanoes that are far from the margins of the tectonic plates appear?
These volcanoes are believed to be above local 'hot spots' on the surface. Hawaii would be the prime example. Most volcanoes occur above the subduction zones at a merging plate boundary. But volcanoes also appear directly at the expanding junction of a pair of plates. Iceland, and some of the South Atlantic islands are examples of this.
Were do volcanoes appear the most?
Volcanoes appear most frequently along the boundaries of tectonic plates, such as the Pacific Ring of Fire, where many active volcanoes are found. These regions experience high levels of seismic and volcanic activity due to the movement and interactions of Earth's tectonic plates.
Do Earthquakes and volcanoes appear all over the Earth's surface or only in certain places?
Volcanoes are just mostly in certain places and are not dotted around anywhere.
How does Mars have volcanoes and ice on it?
In the same way that the Earth has volcanoes and ice. However, Martian volcanoes do not appear to be active.

Are there volcanoes on Antarctica?
yes one of the most popular volcano on Antarctic is mount Erebus
Where do volcanos happen?
Most volcanoes appear at the tectonic plate boundaries where friction between the plates and the mantle makes magma which then push through near the plate boundaries forming volcanoes.

Can volcanoes appear anywhere on earth?
Not just anywhere. Most volcanoes are located at plate boundaries. The rest are located at locations called hot spots.

Is there a volcano which is near a plate boundary?
yes volcanoes could appear or erupt anywhere

Which two geological processes appear to have been the most important in shaping the surface of venus?
volcanoes and tectonics
Where do volcanoes appear on the earths crust?
Volcanoes usually appear near tectonic plate boundaries, where the Earth's crust is thin and magma can more easily reach the surface. They can also occur in areas known as hot spots, where molten rock from deep within the Earth rises to the surface through the crust.
