How is a magma chamber formed in a volcano?
Magma rises through fractures from beneath the crust because it is less dense than the surrounding rock. When the magma cannot find a path upwards it pools into a magma chamber. As more magma rises up below it, the pressure in the chamber grows.
What is an opening that leads from the crater of a volcano down to pools of magma?
Vent
What life is in rock pools?
Rocks contain silicon dioxide and are a compound Above is true. But if the type of rock is igneous, sedimentary, or metamorphic then it can contain minerals, other rock fragments, and magma.
How is a volcano born?
A volcano is formed when 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. This can happen as deep as 100 miles below the earth. Magma settles in pools or chambers near the surface. This is where eruptions take place. 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.
Where do most metamorphic changes to rock occur?
Metamorphic rocks form deep in the earth where high temperature, great pressure, and chemical reactions cause one type of rock to change into another type of rock. Metamorphic rocks begin to form at 12-16 kilometers beneath the earth's surface. They can also form because of small pools of magma rising through the crust.
What connects pools of magma to crater?
A vent tube connects the magma chamber to the vent or crater of the volcano, hence allowing the magma to be released from the volcano and become lava.

Why do volcanos erupt?
When rock inside the Earth becomes hot enough, it melts. This molten rock, or magma, is less dense than the surrounding solid rock. Just as an object that is less dense than water will float on the water, the relatively low density of the magma causes it to rise to the surface of the Earth. In the most common form of volcanism, the type caused by plate subduction, the magma rises and pools into areas beneath the surface called magma chambers. If the pressure continues to increase on the magma within the chamber, it may eventually breach the surface in an eruption. The eruption ceases when the magma chamber is fully or partially emptied, and the process of filling the chamber will begin again (so the process of eruption may occur again). Fissure eruptions occur as a result of a process of convection in the asthenosphere. Heated rock rises in the mantle, melts from decompression, and fills in the gaps created in the crustal rock at divergent plate boundaries. The mid-ocean ridge, the world's longest mountain range, is created from fissure eruptions.'Hot spot' volcanoes (as in the Hawaiian Island Chain) erupt from a constant stream of molten material from a specific point in the Earth's mantle which remains constant as the plates move slowly across it. Eruptions here will be slow and fairly steady as the source and pressure of the magma is constant.The magma that flows from a chamber may harden to form a "plug" or a dome. This kind of structure may enlarge or be pushed upward when the magma cannot freely flow out. The pressure on these rocks is one factor that is monitored by vulcanologists when forecasting the possibility of another eruption from an existing volcano.Volcanoes erupt because the magma underneath them builds upward, and eventually has enough force to shoot or flow out of the volcano.
What kind of energy powers Old Faithful the geyser?
Geothermal I would say, though I am not an expert on geysers
Where are natural geysers found?
Iceland, they are hot pool OS water,heated by magma under the earths crust, 80percent of homes are heated by geothermal energy from geysers and hot pools in iceland
