Extrusive Igneous Its intrusive igneous A+
The type of rock that forms at the edges of cooling magma chambers within the Earth is called igneous rock. Specifically, when magma cools and solidifies slowly beneath the Earth's surface, it forms intrusive igneous rocks, such as granite. If the magma erupts to the surface and cools quickly, it forms extrusive igneous rocks, like basalt. The cooling process and composition of the magma determine the specific characteristics of the resulting igneous rock.
Magma
The Earth started cooling about 4 billion years ago.
Empty magma chambers are geological formations that once contained molten rock (magma) beneath the Earth's surface but have since lost their magma due to volcanic activity or other geological processes. These chambers can collapse, leading to the formation of features like calderas or subsided land. The removal of magma can occur through eruptions, where magma is expelled to the surface, or through crystallization and solidification within the chamber. Empty magma chambers can provide insights into past volcanic activity and the dynamics of magma movement within the Earth.

The cooling rate of a coarse-grained igneous rock is relatively slow, which allows for the formation of large mineral grains. This slow cooling rate typically occurs deep within the Earth's crust or in magma chambers, allowing the minerals to grow and develop over time.

Magma
due to slow cooling of magma within the earth causes the minerals to crystallize.
The Earth started cooling about 4 billion years ago.
The texture of an igneous rock formed from cooling magma deep beneath the earth is typically coarse-grained. This is because the slower cooling process allows larger mineral crystals to form within the rock.
Both basalt and granite are igneous rocks that form from the cooling and solidification of molten rock. However, they differ in their mineral composition and formation conditions, with basalt forming from rapidly cooling lava at the Earth's surface, while granite forms from slowly cooling magma deep within the Earth's crust.
Diorite typically forms in the Earth's crust during the cooling and solidification of magma deep underground. It is commonly found in association with mountain-building processes, such as subduction zones and continental collisions. Diorite can also form through the crystallization of magma chambers within the crust.
Intrusive rocks are formed below the ground, within the Earth's crust, through the cooling and solidification of magma.
