How does volcanoes from and erupt?
Volcanoes erupt when pressure from inside the earth pushes magma through a weakness in the earth's surface. As more and more magma erupts, the volcano is formed and grows.
How are volcanoes and magma related?
Magma is the molten material beneath the surface (crust) of the earth. Magma is called lava when it emerges from the earth in its molten state. The volcano is the geologic structure at the end of a volcanic chimney, which is the duct that connects the magma pocket in the earth through the crust to the surface. The volcano is actually at the "output end" of that volcanic tube.
How volcanoes occur?
Volcanoes occur when the earth cools off, and releases internal heat and pressure. Magma is a lower density than the surrounding rocks, and this causes it to rise to the surface. As it rises, gas bubbles form in the magma, exerting pressure, causing the magma to erupt out of the surface of the earth.
How are volcanoes related to earth?
Volcanoes are found at Convergent and Divergent plate boundaries, where Plate Tectonics is most active. Magma is produced along plate boundaries, like the Ring of Fire around the Pacific Plate, forming volcanoes.
The opening in Earth's crust through which magma rises to the surface is known as the?
The opening in the earth crust which magma rise to the surface are Volcanoes
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.
What all volcanoes share?
All volcanoes are holes in the Earth that hold magma from underground.

What is the hypothesis of volcanoes?
Magma from the mantle of the earth is forced up through fissures in the crust of the earth.

What do volcanoes have?
Volcanoes have magma.
How many volcanoes on your earth?
There are more than 1500 active volcanoes on earth. We currently know that 80 or more are under ocean's, these volcanoes can't produce magma just huge explosions.
Is magma found on earthquakes or volcanoes?
Magma is generally associated with volcanoes
What are Melted minerals?
Molten rock, or in other words, magma or lava. Magma exists beneath the Earth's surface, lava is flowing magma produced by the eruption of volcanoes.
