The right option is C. Magma is injected into surrounding rock forming an igneous intrusive.
An igneous intrusion is a formation in which magma rises up below the surface of the Earth and intrude into other rocks located above it forming an igneous intrusive and leaving them in a dome shape. The magma cools and solidifies before it gets to the surface and it is later exposed as the broken sedimentary rock on top of it gradually wears away. The two types of igneous intrusion are; intrusive and extrusive rocks.
The correct answer is option D, that is, magma is injected into surrounding rock producing an igneous intrusion.
Magma refers to a semifluid or fluid substance within or underneath the crust of the Earth from which the formation of lava and other igneous rocks takes place by cooling. Igneous intrusion produces when the magma from beneath the Earth's surface is gradually pushed up to occupy the cracks or spaces between the rocks and solidifies and cools down prior of reaching to the Earth's surface.
Igneous rock is molten rock.
Igneous rocks form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface.
C. Magma is injected into surrounding rock forming an igneous intrusion.
Igneous intrusion is a natural phenomena in which a molten magma rises up from the mantle and intrude inside the rocks lying above it. The hot magma gets cool inside the another rock, therefore, the structure of the rock being intruded by magma remains stable and unbroken.
