Extruded magma (lava) can cool on the surface, or under water. Magma also cools underground, forming intrusive igneous rocks such as granite.

Is cool magma sinking and warm magma convection?

Yes, cool magma tends to sink due to its higher density compared to warmer magma, which rises due to its lower density. This movement leads to convection currents in the magma chambers beneath the Earth's surface.


What temperature does magma solidify?

The composition of the magma effects the temperature it will cool and solidify at. In general most magma solidify at about 1,200 degrees Fahrenheit.


Are magma and lava sedimentary rocks?

No. Magma and lava are molten rock. When the cool they form igneous rock.


What does magma need to do for a rock to form?

Magma needs to cool and solidify to form a rock. This process can happen underground, resulting in intrusive rocks, or at the surface, leading to extrusive rocks. The rate of cooling and the mineral composition of the magma will determine the type of rock that forms.


Why can different types of igneous rock form?

Because there are different types of magma and different pathways for that magma to cool.


When does magma stop flowing?

When it becomes too cool, and then it will solidify.


Why does magma cool?

Magma cools because it losses heat to its surrounding environment, either due to convection or contact process.


What rocks cool from magma or lava?

magma cools into intrusive igneous rock while lava into extrusive igneous rock


What kind of rock can magma turn into?

Magma can solidify and cool to form igneous rocks such as granite, basalt, or andesite, depending on the composition and cooling rate of the magma.


Do large crystals form when magma and lava cool slowly?

Yes.
