What else can I help you with?
What must be present for magma to form into igneous rock?
Igneous rocks develops when magma comes through the crust and cools.
Which of the Earth's layers does the magma come?
Magma is fluid molten rock that exists under the Earth's crust.
Why does magma rise through the crust above it?
Magma rises through the crust due to differences in density between the magma and surrounding rock. Magma is less dense than the solid surrounding rock, so it moves upwards through cracks and fractures in the crust. As it rises, magma can also be driven by pressure differences and heat from the Earth's mantle.
Why does magma in the mantle rise through the crust above it?
magma comes from the outer core and when an earthquake or something happends, a crack froms and the pressure of lava shoots up like a geyser.
Is a caldera the same as a volcano?
No. A volcano is a vent or fissure in the ground through which molten rock, ash, and gas can erupt from within the Earth. A caldera is a large depression in the ground that forms during the most violent volcanic eruptions when a volcano collapses in on itself.

Where do you get your magma from?
Magma comes from the melting of material in the crust or upper mantle.

The movement of magma through the Earth's crust is known as?
The movement of magma through the Earth's crust is known as intrusion.

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 does a caldera happen?
the roof of the magma chamber collapses forming caldera
When lava breaks through the earth's crust?
that is a volcano starting 100 years would pass and then it becomes more of a volcano.
What is an area where magma melts through the crust in the middle of a plate?
A hot spot is an area where magma from deep within the mantle rises through the crust in the middle of a tectonic plate, creating volcanic activity and forming a chain of volcanic islands or seamounts. The Hawaiian Islands are a well-known example of hot spot activity.
What is formed when the top of a volcano collapses into a partially emptied magma chamber?
what happens is that it forms a caldera
