Hmm... I wouldn't quite put it that way that volcanoes started life on earth, but they are definatly a contributing factor. Volcanoes push nutrients up from deep underground, and the rock that comes up around them is very nutrient rich. Around volcanoes, geysers and hot springs also often formed. A theory of where the water in them may have come from is comets. Scientists have proven that strands of RNA (ribonucleic acid), a basic building block of life, will form on its own, and such nutrient rich superhot waterpools are literally hotspots for them to form, along with amino acids, subunits of proteins, another important part of living organisms. Viruses, the predeccessors to life, would most likely have flourished in such pools, eventually evolving into a primitive form of bacteria known as Archea that to this day inhabit superhot pools of water. These Archea would eventually evolved into modern bacteria.
What else can I help you with?
Does the moon and earth both have active volcanoes?
The earth obviously does. The moon does not.
The major branch of earth science that studies volcanoes is called?
The major branch of volcanoes is Geology.
Why do volcanoes support the theory of plate tectonics?
Volcanoes are caused by the magma from the Earth's mantle; this magma is released through faults in the Earth's tectonic plates.
Do volcanoes occur randomly over Earth's surface?
Volcanoes do not occur randomly over Earth's surface. They occur along the located mark of plate boundaries.

How will you differentiate a volcano based on its structure?
Volcanoes are a good way for the earth to blow off a little steam. More correctly, volcanoes are vents in the earth's crust through which lava, rock fragments, hot vapor and gases are ejected. And while they are all natural events in the life of earth, there are different types of volcanoes. The types of volcanoes are differentiated based on their size, composition and explosive style.
Is mars the only planet with volcano?
No. Earth (obviously) and Venus have volcanoes as well.
Was there life on earth from the start?
No, the Earth was uninhabitable for millions of years.
