A pluton is a body of rock formed from the cooling of magma under the surface.
Crystals tend to be large if they form slowly either from the melt or from solution. Intrusive igneous rocks are formed when magma forces its way between existing rocks and then gradually cools and sets. The surrounding rocks provide good insulation, so the magma cools very slowly, and big crystals, such as those in granite, are formed. Chemical sedimentation processes vary, but are usually more rapid than intrusive igneous cooling.
The flowchart typically shows that after magma leaves the pipes, it can either erupt onto the Earth's surface as lava through a volcano or it can solidify underground to form intrusive igneous rocks like plutons or dikes.
Crystals formed from slow cooling typically have larger crystal sizes due to more time for the atoms to arrange in an ordered structure. This results in minerals with well-defined crystal faces and clearer textures, as seen in intrusive igneous rocks like granite and gabbro.
No, magma is already in a molten state. It is a mixture of molten rock, gases, and solids that exists beneath the Earth's surface. Magma can solidify to form igneous rocks when it cools and crystallizes.
Bubbles in rock form when gas-rich magma cools and solidifies without the gas being able to escape. The trapped gas forms bubbles within the cooling rock, creating a porous texture. Over time, the solidified rock with bubbles can become a type of volcanic rock called vesicular basalt.
granite is all that i know of.
igneous rocks
Intrusive igneous rocks.
Igneous rocks form because, magma cools under the ground, or magma erupts, then cools on the ground forming these rocks.
formed when molten rocks called magma becomes trapped in small pockets . As these pockets of magma cools slowly underground, the magma becomes igneous rocks
The molten material that forms igneous rocks is called magma when it is beneath the Earth's surface and lava once it erupts onto the surface. As magma cools and solidifies, it crystallizes to form igneous rocks. These rocks can be classified into two main types: intrusive (or plutonic), which form from magma that cools slowly underground, and extrusive (or volcanic), which form from lava that cools quickly on the surface.
Igneous rock is what forms when magma cools and hardens.
Intrusive igneous rocks
They form when magma or lava cools and solidifies.
Igneous rocks are formed when molten magma cools and solidifies either beneath the Earth's surface (intrusive) or on the surface (extrusive). Intrusive igneous rocks are formed from magma that cools slowly underground, while extrusive igneous rocks are formed from lava that cools quickly on the surface.
The magma cools and forms both rocks
It will form granite if it cools underground and rhyolite if it cools at the surface.
