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.
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.
Yes. Magma is underground molten rock.
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 basalt and gabbro. These rocks are dense, fine-grained, and dark in color. They are commonly found in oceanic crust and volcanic islands.
Intrusive igneous rocks form when magma cools below the Earth's surface. Thus, intrusive rocks are associated with magma. Lava, on the other hand, is molten rock that flows onto the Earth's surface, forming extrusive igneous rocks.
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.
Lava and magma are two forms of melted rocks
Yes. Magma is underground molten rock.
Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.

The magma cools and forms both rocks

Igneous rocks.
Basalt
Igneous rock is what forms when magma cools and hardens.
Basaltic magma usually forms a black rock.
Igneous rocks are formed underground from a very hot substance called magma. As magma cools and hardens under extreme pressure, it forms igneous rocks.
