Intrusive igneous rocks. These have large crystals because it is warmer underground, therefore it has more time to cool, therefore the crystals have more time to form and grow, thus large crystals.

How does magma affect the rocks into which in intrudes?
Magma is molten rock that bubbles up along ocean ridges to form new crust. Another way that magma forms new crust is when it is expelled out of a volcano and becomes lava, which cools and hardens into crust.
Magma forms when rocks begin to melt?
Yes. Magma is underground molten rock.
Magma that is rejected during a volcanic eruption forms igneous rocks?
Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.
Low silica magma forms rocks like?
it forms Basalt.
What is the purpose of dikes?
It depends, as there are different kinds of dike. One kind of dike, which may also be called a levee is a slope or wall along the banks of a stream or other body of water that holds it back, preventing or limitng flooding. These may be man-made or can form by the natural deposition of sediments. Another kind of dike releates to igneous geology. This kind of dike forms when magma, or molten rock intrudes through rock, cutting across the rock layers, often vertically, as opposed to a sill, which forms between and parallell to the layers.

What forms when rocks or minerals partially or completely melt?
Lava and magma are two forms of melted rocks

Yes. Magma is underground molten rock.

What type of rock forms from magma?
igneous rocks
When Magma is cooled what rock forms?
igneous rocks
How do gabbro and basalt rocks form?
The magma cools and forms both rocks

What color rocks does basaltic magma form?
Basaltic magma usually forms a black rock.
What rocks form when magma cools and hardens?
Igneous rock is what forms when magma cools and hardens.
What rock group forms by the solidification of magma?
Igneous rocks.
