Chalk, primarily composed of calcium carbonate, cannot directly become magma. However, under extreme heat and pressure in the Earth's crust, chalk can undergo metamorphism, breaking down into different minerals like limestone, which can eventually contribute to the formation of magma through processes like melting. This transformation occurs over geological timescales and requires specific conditions, including significant heat.
What else can I help you with?
A mineral never found in igneous rocks is?
chalk. Chalk is a type of limestone composed mainly of the mineral calcite, which is a sedimentary rock forming in marine environments. Igneous rocks are formed from the cooling and solidification of magma or lava, so chalk is not typically found in igneous rocks.
When rocks are pushed down into the mantle and melt it become?
When rocks are pushed down into the mantle and melt, they become magma. Magma is molten rock located beneath the Earth's surface.
Does lava flow to the surface and become a magma?
No. Magma flows to the surface and becomes lava.
Which point does magma become lava?
In definition, lava is magma that is expelled by a volcano at or near the surface.
Is gypsum used in chalk?
Yes, gypsum is used in chalk production as a main ingredient. When heated, gypsum undergoes a chemical process to become calcium sulfate hemihydrate, which is then used as the binding agent in chalk.
Do sedimentary rocks melt and become magma?
No. It's the Metamorphic rocks that melt and become magma.

Does lava flow to the surface and become a magma?
No. Magma flows to the surface and becomes lava.
What does magma become when it cools and hardens?
rock
How does a metamorphic become magma?
Extreme heat.

What does magma become once it rises to the earth's surface?
Magma that reaches the Earth's surface is known as lava.
How does a metamorphic rock become magma?
Extreme heat.
Can rising magma become less fluid as it decompresses?
Yes, rising magma can become less fluid as it decompresses. When magma rises towards the surface, the pressure decreases, which can cause dissolved gases to come out of the magma and create gas bubbles. These gas bubbles can increase the viscosity of the magma, making it less fluid.
What does high level of silica cause magma to become?
High levels of silica cause magma to be more viscous
