Earth is ruptured when pieces of earth’s crust called tectonic plates hit each other. One of the plates goes under the other. This is where the earth heats and melts the rock into magma and gases. Volcanoes can also be formed when the plates go away from each other. The magma pushes up and lava forms. These types of volcanoes are found on the ocean floor.

Fantastic things related to Volcano activity.


A geyser is a type of hot spring that erupts periodically, ejecting a column of hot water and steam through small vents into the air.

“Geyser” in the Haukadalur valley, Iceland, is the oldest known natural geyser in the world.


A cone shaped mountain is built up by lava which is poured out from the vent and then covered by ash.

Volcanic Cone, Monument Valley, Utah


Saucer shaped craters at the tops of volcanic cones, created by the collapse of the cone during huge explosion.

Aniakchak Caldera formed during an enormous explosive eruption that expelled more than 50 km3 of magma about 3,450 years ago.

Giant’s Causeway

Hexagonal basaltic columns that are formed of cooled lava from ancient volcanic activity.

The Giant's Causeway on the Antrim coast of Northern Ireland.

Like wounds in human body, the aftereffects of the volcano activity on the earth surface stands testimony to the ruptures that nature causes to the earth.
