What else can I help you with?
What do you call a gap in the earths crust through which molten rock escapes onto the earths surface?
Volcano or shield volcano.
An opening in the earth's crust from which volcanic materials pass through to the earth's surface is called an?
a volcano probobly
When does magma become lava?
It should be magma is the hottest because it is usually molten rock that has not reached the surface during an eruption.Lava is 2nd hottest. It is the molten rock we see when a crack in the crust of the earth or a volcano eruption allows molten rock from beneath the crust to come up.
Part of the earth's crust above water?
The part shown above the water is known commonly as land.
Is it hotter below or above ground?
below because the mantle and crust
What are the geological conditions for a volcano?
For a volcano to erupt the pressure from magma beneath the surface of the earth's crust must exceed the weight of the crust above it
Does lava comes from a volcano?
A volcano is the opening in the crust through which lava comes forth.
How is a Volcano built?
After many many years the rock grows taller and taller because the volcano keeps erupting and cooling, making the volcano bigger and bigger. Magma (lava) seeps through cracks in the earths crust, it cools and hardens to form a cone shape on the surface. This happens repeatedly over hundreds of years thus eventually forming the cone shape of a volcano.
Which parts of the volcano are solid?
The main solid parts of a volcano include the crust of the Earth, the volcanic rock that forms the cone and vent of the volcano, and the hardened lava flows. Beneath the surface, there are also solid magma chambers where molten rock accumulates before erupting.
What happens as a result of molten rocks building up pressure under earths crust?
An erupting volcano occurs when the pressure of the molten lava beneath becomes too great.
What is a hole or crack in the earth's crust through which magma rises to the surface called?
It is called a volcano.
What kind of volcano is formed when magma breaks through the crust?
That definition could apply to any volcano.
What is an opening in Earth's crust through which lava flows?
An opening in Earth's crust through which lava flows is called a volcano. When pressure from molten rock beneath the surface builds up, it can erupt through the volcano, releasing lava, ash, and gases into the surrounding area.
What is an opening in earths crust through which gases and melted rock pass?
volcano
What do you call a gap in the earths crust through which molten rock escapes onto the earths surface?
Volcano or shield volcano.
What An opening in the earth crust through which lava hot gases and rock fragments erupt?
Volcano , (volcanic vent).
What is the mechanism that creates a volcano?
The molten core of the planet releasing energy through the crust.
